Anthropic’s Fable 5.2 pushes the AI frontier
- Fable 5.2 leads coding and research benchmarks, while Mythos 5.2 and GPT-6 Cyber put cybersecurity in focus.
- New capabilities still need human review, access controls and spending decisions before benchmark wins become everyday value.
Anthropic’s Fable 5.2 has moved ahead of rival models on coding and agentic scientific research, while its Mythos 5.2 sets a new benchmark in cybersecurity. OpenAI’s GPT-6 Cyber has also arrived, in a burst of releases that shows how quickly frontier AI is moving into consequential work.
On coding tests, Fable 5.2 led previous top models by several points; on an agentic science benchmark, it opened a six-point lead. Nathaniel Whittemore of The AI Daily Brief also highlighted its Remote Labor Index score: 41.3% of tasks completed, nearly double Opus 5.5’s 21%. That test measures defined contractor tasks, however, not the full range of office work.
The cybersecurity gains bring a sharper question: who gets access to powerful tools that can find vulnerabilities? Whittemore said Mythos 5.2 led previous cybersecurity models by about 10 percentage points. This Week in AI reported that GPT-6 Cyber was rated critical, OpenAI’s highest preparedness risk tier, and stayed within its stated scope 99.93% of the time, up from 94.49% for GPT-5.6. The labs said they were restricting their highest-risk cyber capabilities to vetted organizations; Fable remained broadly available with safeguards.
Anthropic has also presented Fable 5.2 as a tool for work well beyond coding. The company reported scientific projects in physics and protein design, and said agents using the model formalized Fermat’s last theorem in 30 hours. Those examples suggest the promise of giving models longer, more complex projects, but company demonstrations do not establish how reliably they will work in everyday research.
The gap between capability and usefulness remains visible. Ethan Mollick called Fable 5.2 “almost AGI,” but said it could produce detailed work without recognizing when it was dull or poorly judged. Whittemore saw the same problem in his own tests: impressive demonstrations did not always show a strong sense of what people would find interesting. Human review still matters, even when a model can keep working for hours.
Cost matters, too. Anthropic cut Fable 5.2’s token prices by 20%, but Whittemore noted that its maximum-effort benchmark tasks cost $26.54 each, 2.6 times as much as Opus 5.5. Anthropic recommends lower effort settings for ordinary use and saving the most expensive setting for demanding work. The frontier is advancing; deciding when the extra capability is worth the cost, and how safely to deploy it, remains part of the job.

- Deep dive into what was said in the episodes
Jensen’s Departure, NVIDIA’s succession plan, AI doomer response, and Demis talks RSI | MOONSHOTS #311 (recorded live) • Nov 14
- A creator used Fable 5.2 to reconstruct ancient Babylon from historical documents and archaeological plans in eight hours. The hosts described such tools as early steps toward interactive historical worlds and large-scale computational archaeology using accumulated records and imagery.
Also discussed on this episode: (14)
Big Tech (1)
- Peter Diamandis said an Outlook outage disrupted his work and cited 100,000 to 130,000 reported user problems. The hosts linked communication failures to cyber risk from agent swarms attacking exposed systems.
Space (2)
- Peter Diamandis said Starship Flight 15 was scheduled for Friday the 13th, with a booster catch and a Starship catch 22 hours later. He speculated that launches could eventually reach 1,000 or even 10,000 per year.
- A researcher used Claude to search Vera Rubin Observatory data and identify a candidate dwarf planet, estimated at 590 kilometers wide and roughly twice Pluto’s distance from the Sun. The hosts argued that AI can uncover discoveries already present in archives but missed by human analysis.
Chips (2)
- Peter Diamandis presented Jensen Huang’s resignation as potentially connected to reported affairs and alleged chip diversion through Singapore to China; Alex Wissner-Gross argued that U.S. officials may have pushed the story to support export controls. Speakers stressed that the allegations were unproven.
- NVIDIA named CFO Colette Kress interim CEO and Harvey Jones board chair. The hosts said a successor must preserve CUDA and TSMC relationships, investor confidence, and NVIDIA’s role in financing AI companies; Alex Wissner-Gross warned that Jensen-style founder leadership may be hard to replace.
Safety (2)
- Paul Christiano warned of a high risk of AI takeover within three years, while acknowledging that no quantitative model supports a precise probability. Immad Akhund rejected the takeover framing, pointing instead to cyber and biological risks; Akhund said his own p(doom) had fallen from 50% to 20%.
- The hosts argued that AI labs should make alignment work concrete and public, with independent oversight and clearer definitions. They debated whether training data should encode shared values, warning that a U.S. national ideological test could resemble the Chinese Communist Party’s required ideological review of public models.
Models (1)
- Demis Hassabis warned that closed-loop recursive self-improvement without human review could accelerate AGI and produce systems difficult to understand or control. The hosts disagreed on how close labs are to that point, citing automated training, model swarms, and the difficulty of meaningful human oversight at scale.
Enterprise (1)
- Anthropic launched Claude Whiteboard and Sheets in beta, Claude Data generally, and Claude Meetings for Google Meet; it also added connectors for third-party apps. The hosts saw agents displacing software interfaces, while noting that Microsoft retains distribution, compliance, support, and enterprise permissions.
Health (1)
- Dario Amodei said cancer, Alzheimer’s, heart disease, and mental illness could become relics within a decade. Immad Akhund estimated that AI could identify core disease mechanisms in two to three years, but said translating discoveries into cures could take five to ten years; the hosts emphasized virtual cells and faster trials.
AI Infrastructure (1)
- Planet launched an AI app that lets users query a decade of satellite imagery across more than 3,000 layers. Separately, an agent search of public NASA lidar data flagged a possible Mayan site in Mexico; 48 agents screened 1,200 square kilometers, and officials called it an original finding.
Labor (1)
- Immad Akhund said UBI needs to arrive before job displacement and unrest, citing successful prior experiments but warning that some states block local trials. Peter Diamandis predicted federal payments of $3,000 a month if conditions deteriorate, while Alex Wissner-Gross argued AI could also help solve social and political problems.
VC (1)
- Immad Akhund said NVIDIA often invested 10% to 20% of AI funding rounds and sometimes committed billions to strategic companies; he expects that funding to retreat after Huang’s departure. He argued that investment may shift toward automated wet labs and robotics, while Anthropic’s IPO could add liquidity.
Reasoning (1)
- The hosts argued that AI may discover concepts humans cannot formulate or verify, while disagreeing over whether advanced models will be alien or increasingly humanlike. Alex Wissner-Gross cited brain-activation decoding research; Immad Akhund said AI could help solve economic and social transitions as well as scientific problems.
The avalanche that hit math is coming for AI development • Nov 13
- The host says three months of progress changed his view from superintelligence being at least a decade away to AI researchers reaching the best humans within a few years, possibly months. He expects AI experts across fields by 2030, plausibly as early as next year.
- Meter found Anthropic's progress on well-scoped tasks was twice as fast as a year earlier, and attributed most of the acceleration to AI use. Anthropic said Claude led 26% of its AI R&D work, up from under 1% in February; OpenAI reported heavy researcher use of coding agents.
- The host traces a sharp rise in mathematical ability: models struggled with four-digit addition in 2023, barely handled high-school contest problems in 2024, won IMO gold in 2025, then began solving open problems. OpenAI reportedly solved a Millennium Prize problem in 88 hours.
- Toby Ord argues current AI can automate proof work but shows little evidence of asking powerful questions or opening new mathematical fields. The host says this limitation matters less in machine learning, where useful empirical recipes have often mattered more than theory.
- The transformer illustrates how AI could automate research by combining known ideas through persistent experimentation. Attention, residual networks, and other components were already familiar; the breakthrough required joining roughly half a dozen existing techniques in a configuration that worked.
- The host's median forecast is that AI researchers will match the best human AI researchers in 2028, assuming labs keep pushing and governments do not slow them. He assigns at least a 25% chance to a date after 2032, while 2027 remains plausible.
- Automated researchers could work around the clock at roughly 10 times human speed, packing about 50 times as much work into a calendar week. The host estimates the top 50 researchers drive 80% of frontier-lab algorithmic progress, while modular, checkable tasks let many agents work in parallel.
- The host sees two possible outcomes after AI research is automated: a software-only singularity if research capability improves faster than ideas get harder, or a spark if idea scarcity wins. He assigns each outcome a 50% chance and says the spark could compress three to six years of progress into one.
- In the spark scenario, the host expects a GPT-3.5-to-GPT-6-scale leap within 12 months, producing systems far beyond humans on verifiable tasks. He speculates such models could design better accelerators than Nvidia, outperform human trading firms, and find a room-temperature superconductor.
- The host expects RL to build transferable skills through vast simulated environments, held-out tasks, and historical backtests. He points to current models navigating unfamiliar codebases and argues that evolution also produced broad human abilities from a crude survival-based verifier.
- The host expects superhuman learners to reach top performance in new fields within months of deployment, not decades. He compares their potential ramp-up with Napoleon's early military victories and Rockefeller running a major refinery after two years in oil, then describes parallel access to a company's records and staff.
- Even if software progress slows, the host expects AI systems to accelerate compute growth by designing chips and fabs and helping build data centers with robots. Global AI compute has grown about threefold annually for five years, while robotic construction would take years longer than a software-only take-off.
- The host groups AI R&D into pre-training, post-training, and inference efficiency, arguing that each has measurable proxies. These proxies can train models directly and let agents check their work before combining contributions; sample efficiency and online learning can also be measured.
- Pre-training research can optimize held-out loss and test whether small-scale improvements transfer to larger models. The host says better pre-training can produce smaller, cheaper models and faster research loops; AI Lab Magic reported matching leading open models with half the compute used for GPT-3.
- Post-training proxies include the compute, data, and time needed to learn new tasks, performance on unfamiliar environments, and direct AI R&D benchmarks. The host cites EdgeBench and Anthropic's CoBench; inference efficiency can be checked through utilization, cache size, FLOPs, and latency.
- The host says continual learning may not block automation: long in-context sessions could substitute for weight updates, and continual learning itself has testable research proxies. He also argues existing benchmarks can capture paradigm shifts, while AI-generated data can address data limits; one analysis found pre-training data improvements contributed over three times as much as model improvements.
- Experiment compute may constrain agent swarms, but the host says labs have been expanding compute fast enough to give 10,000 agents a GPT-3-scale training run daily by the end of 2027. Agents could spend more labor on small experiments, analyze every rollout, and improve extrapolation from small-scale results.
Alex Finn: Anthropic has the best model, Grok has the best harness | TWiAI 39 • Nov 12
- Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, while OpenAI released GPT-6 Cyber; the labs restricted their highest-risk cyber capabilities to vetted organizations, and Fable remained broadly available with cyber and biology safeguards.
- Alex Finn called Fable 5.2 the best model he had used, citing faster, cheaper, stronger recent Anthropic releases and a complex video game built over two weeks without his input. Sarah Hooker argued the changes mainly reflect cost pressure, while Manu Sharma credited broad scaling across reinforcement learning, multimodal capability, and model behavior.
- GPT-6 Cyber was rated critical, OpenAI's highest preparedness risk tier, and reportedly stayed within its stated scope 99.93% of the time, up from 94.49% for GPT-5.6. The host framed the release as a response to rising cyber threats and companies' demand for stronger defenses.
- Alex Finn said Grokbot's harness delivers more value for everyday knowledge work than Claude for his team, while Sarah Hooker said Anthropic deliberately keeps its model and harness tightly coupled. Manu Sharma distinguished routine work suited to smaller models from long-horizon science and engineering tasks that still benefit from frontier models.
Also discussed on this episode: (13)
Enterprise (1)
- Manu Sharma said enterprise integrations, IT controls, memory, and accumulated context create substantial application-level lock-in, even as small teams switch tools freely. Sarah Hooker warned that open-weight models and automated self-improvement are making API dependencies less sticky.
Markets (2)
- Anthropic's updated IPO filing set a $70 to $78 share range, implying up to $1.405 trillion fully diluted value; strategic investors agreed to buy $26 billion of stock. Alex Finn questioned how a model company could grow tenfold without a durable moat, while Sarah Hooker argued Anthropic must move into vertical products such as legal, tax, healthcare, and finance.
- Manu Sharma said Anthropic generates more than 80% gross margins and that Claude writes 90% of its own training code, giving the lab an internal advantage. He said improved compute efficiency supports those economics, while lower prices could drive usage growth above the price reduction.
China (2)
- Sarah Hooker said export controls have been difficult to enforce because Chinese firms can use data centers in nearby countries, while China is also developing domestic chips and optimizing models for efficiency. Manu Sharma added that Chinese labs can use remote compute through APIs, so chips need not sit on the mainland.
- The host reported allegations that Nvidia executive Alice Wong helped divert chips to Chinese companies, including an alleged $7.5 billion shipment, and said Nvidia's board found no reason to believe secrets or national security were compromised. The board opened an independent investigation, and Reuters had not independently verified the reported figures.
Chips (1)
- Alex Finn argued Nvidia should not remove Jensen Huang absent evidence he deliberately harmed US security, calling Huang central to the company. Sarah Hooker said the export-control story highlights compute as a strategic resource, while Manu Sharma questioned whether restrictions can stop Chinese AI development.
Regulation (1)
- The host described HR 3447, the Chip Security Act, as requiring location-verification mechanisms for covered chips and reporting when hardware is diverted. Alex Finn argued export controls will be circumvented when demand is strong, while the host predicted the bill would advance after the Nvidia allegations.
AI Infrastructure (2)
- Sarah Hooker said US opposition to data centers reflects broader anxiety about AI and can obstruct essential infrastructure through local processes. Manu Sharma said developers and governments need clear, locally relevant evidence about jobs and tax revenue; both rejected unsupported claims about water and pollution as poor grounds for debate.
- A proposed $5 billion data-center campus at the former Landover Mall site stalled after local protests and petitions; the mall had been demolished, leaving vacant land. The host alleged foreign-backed groups may be fueling opposition, citing Sam Lyman's claims, while Sarah Hooker said public receptivity to AI matters more than tracing money flows.
Adoption (1)
- Alex Finn said his parents became enthusiastic about AI after ChatGPT helped them repair a broken door, and argued that practical AI education would build lasting support for data centers better than giveaways. The discussion also cited a Geely model priced at $9,000 that had displaced Tesla's Model Y as China's top-selling car.
Safety (1)
- Fireworks AI said attackers accessed customer datasets and unfinished models after using internal credentials, then attacked computers holding research data. The company blamed model-access theft and resale; CEO Lynn Xiao said the attackers' behavior suggested AI agents were involved.
Startups (2)
- Sarah Hooker said Adaption Labs automates fine-tuning and continuously updates models using a company's context, aiming to make smaller models useful without the manual tuning process she said many firms found difficult. Manu Sharma described Labelbox's Recursion as an enterprise agent platform for recurring technical work such as underwriting, research, and model training.
- Alex Finn described Henry Intelligent Machines as an agent that learns a user's skills and helps build businesses around problems that user can solve. Finn said the product was preparing a waitlist and envisioned agents creating value while their users pursue other work and interests.

Nathaniel Whittemore
Wall Street Has No Idea What Anthropic Is Worth • Nov 11
- Google released Gemini 4 Carbon after a two-week preview period and voluntary safety testing; Fable 5.2 had since taken the Artificial Analysis Index lead. Ethan Mollick praised Carbon’s multimodal video recreation and distinct strengths among frontier models.
- Google’s coding gains include Carbon’s analysis of Signal machine code to formally verify security properties, a task Pushmeet Kohli said could take teams decades. Pavel Hurin’s bug hunt found 57 of 105 bugs for $31, close to Fable 5.2’s 58 bugs at nearly $140.
Also discussed on this episode: (12)
China (1)
- Reporting alleges that as much as $7.5 billion in NVIDIA chips reached Chinese companies through Megaspeed, whose employee Alice Huang is accused of spying for China. The New York Times reported that a Commerce Department investigation was halted after NVIDIA counsel contacted investigators; new controls may close remote access.
Chips (1)
- Trump publicly defended Jensen Huang as an honorable CEO, while NVIDIA’s board investigates and weighs governance options without a succession plan. NVIDIA shares fell 11%; the company represents 7% of the S&P 500 and about 8% of the Nasdaq.
Open Source (1)
- Booz Allen switched to open source by adopting NVIDIA’s Nemotron, a small but notable example of enterprise use of NVIDIA’s model ecosystem.
Startups (3)
- OpenAI reported Q3 revenue above $10 billion, up 50% from Q2, alongside operating losses of $10.1 billion to $10.9 billion. API demand and image models helped growth; advertising reached a $1 billion annualized pace, while Q2 growth lagged Anthropic’s.
- Anthropic plans to go public before Thanksgiving, with Dario Amodei pitching a balance between AI’s benefits and risks. On military use, Amodei said the military decides how to use the technology, while providers set only high-level boundaries.
- Anthropic’s reported IPO range is $70 to $78 per share, implying a $1.25 trillion to $1.4 trillion valuation and a $57 billion to $64 billion raise. Partner investment and a greenshoe could bring the total stock floated to about $100 billion.
Agents (2)
- OpenAI acquired Odessia, an AI travel agent founded by Francis Davidson, and shut down its service after the deal. Odessia booked $60 million in travel across tens of thousands of users last summer; Davidson previously built Sonder, which filed for bankruptcy in 2025.
- OpenAI’s business hub adds advertising analytics and brand-controlled agents that answer consumer questions after an ad click. The host sees these tools moving ChatGPT further into commerce, where product discovery and shopping already overlap with answers to user queries.
Markets (2)
- Earlier $2 trillion, $1.6 trillion, $1.5 trillion, and $1.1 trillion valuations came from investor or press speculation, not confirmed Anthropic targets. The host argues the shifting figures show investors lack a stable view of fair value or expected demand.
- John Ma described a bearish case based on flattening revenue and falling token prices, but Anthropic reported run-rate revenue of $81 billion by October’s end. Sonali Basik said a $1.4 trillion valuation equals about 40 times trailing revenue, versus Palantir at roughly 55 times.
AI Infrastructure (1)
- Anthropic disclosed $10 billion in new Microsoft and Google compute commitments spread over seven years, while a $35 billion Lambda deal could be canceled after a missed deadline. The host says the risk may sit with neoclouds’ ability to finance and build data centers on time.
Enterprise (1)
- Anthropic launched Claude Sheets, Whiteboards, and Data, bringing spreadsheet collaboration, project planning, and live CRM or database feeds into Claude. Its legal team cut marketing reviews from three days to 24 hours, while Microsoft shares fell 2.2% on the launch.
Fable 5.2 Is the Best AI Ever. So Why Am I Not Switching Yet? • Nov 10
- Nathaniel Whittemore says Fable 5.2 leads coding and agentic scientific research, while Mythos 5.2 sets a new cybersecurity bar. The reported margins over the previous leaders were 4 points in coding, 6 in research, and about 10 percentage points in cybersecurity.
- Fable 5.2 completed more agentic knowledge-work tasks than several rivals, but its AA Briefcase ELO remained below Opus 5.5. On the Remote Labor Index, it nearly doubled Opus 5.5, a result Garrison Lovely called alarming while noting the tasks are more defined than typical office work.
- Fable 5.2 took the top three positions on the Artificial Analysis Intelligence Index across effort settings. Artificial Analysis credited gains in science, knowledge, and coding, with less progress in agentic knowledge work and terminal coding.
- Anthropic cut Fable 5.2 token prices by 20%, but high-effort use can still cost more per task than Opus 5.5. Anthropic recommends medium by default, high for everyday coding, extra high for measurable long-running work, and max only for testing the model’s ceiling.
- Anthropic says Claude writes 90% of its code changes under human supervision and uses Fable 5.2 for difficult bugs and projects other models cannot justify. Its showcase operating system involved more than 1,000 subagents working for eight days, while the model also handled a Python-to-Rust production-service migration.
- Anthropic reported scientific work spanning theoretical physics, protein design, and formal proof. Fable 5.2 formalized Fermat’s last theorem with agents, while its capsid modeling could help biologists design gene-therapy delivery structures faster and more cheaply.
- Anthropic’s robotics demo showed Fable 5.2 controlling two robotic arms on tasks it had not explicitly been trained to perform. The company said it outperformed most models built specifically to control robotic arms, extending the general-purpose model advantage into physical control.
- Early users reported strong vulnerability discovery. Leander Builds said Fable 5.2 found severe issues created by Opus 5.5, while Pavel Hurin’s planted-bug test found 58 bugs, seven more than the previous best, with fewer turns and lower cost than Sonnet 5.5 Max.
- Fable 5.2 produced more detailed Blender scenes than Opus 5.5 and generated a polished short video advertisement live. Nathaniel Whittemore says the demos show that code generation can create visual work with richer detail, lighting, and physics, though those displays do not establish broad everyday usefulness.
- Ali K. Miller used Fable 5.2 for projects ranging from a government-data map to an ADHD-themed YouTube channel and a 3D task-management game. Miller trusted it more than other tested models, but noted obvious color and unit mistakes and overlapping slide text that its secondary agents missed.
- Every’s team said Fable 5.2 could build a production-grade video editor by combining editing, effects, and music tools, with less supervision than Opus 5.5 required. The result revived the idea of professionals building custom software, though the time and maintenance burden may still make established SaaS products preferable.
- Ethan Mollick called Fable 5.2 “almost AGI” because it handled complex work but failed to judge its own quality. He described accurate yet joyless course material, repetitive writing, and overbuilt rules; critics and fact-checkers caught errors, but did not recognize when the work was dull or poorly judged.
- Nathaniel Whittemore found Fable 5.2’s sense of human interest unreliable: its standard-interface showcase favored difficult-to-verify intellectual tricks, while its coding-harness film was more compelling. Its first proposed research episode also measured launch-to-access delays that Whittemore judged irrelevant to current model users.
- Fable 5.2’s clearest new use may be ambitious work rather than routine efficiency. Nathaniel Whittemore sees playable games as a promising test: users reported functional game mechanics, including a Harry Potter-themed battle royale, and Anthropic’s Sholto Douglas said the model cleared his bar for fun, beautiful games.
- Advice from Anthropic and early testers favors assigning Fable 5.2 whole, open-ended projects, setting approval boundaries, and asking it to critique an idea before building. Anthropic also recommends telling the model it owns the codebase; Nathaniel Whittemore says the model’s strengths and best workflows may take weeks of experimentation to understand.
What the Internet Boom Teaches Us About the AI Buildout | Mike Volpi • Nov 11
- Mike Volpi says current AI providers have a faster revenue ramp than internet businesses did in the 1990s, making AI capacity more practically useful today. Anthropic, OpenAI, and open-model providers such as Fireworks and Together are seeing rapid growth.
- Mike Volpi says silicon manufacturing, not power, is the main near-term limit on AI capacity, and more fab capacity is unlikely to arrive quickly. He expects customers to route simpler workloads to cheaper models as the cost gap between frontier and lower-cost tokens becomes harder to ignore.
- Mike Volpi says scale naturally concentrates businesses such as cloud computing, so NVIDIA financing smaller providers may support innovation but cannot guarantee they survive. He also describes the AI cycle as unusually compelling because bottlenecks across the technology stack create opportunities for new companies.
Also discussed on this episode: (14)
AI Infrastructure (6)
- Mike Volpi says the 1990s internet buildout anticipated commerce, social networking, audio, and video before those applications existed. WDM later multiplied fiber capacity by adding wavelengths, in some cases increasing capacity 40 or 80 times.
- Mike Volpi expects AI infrastructure to remain useful even if today’s builders lose ownership after an industry correction. He says many of the roughly 200 neoclouds have weak balance sheets, while fiber assets from the internet bust remained useful under new owners.
- Mike Volpi says AI infrastructure draws more capital-market financing than the 1990s buildout, when equipment vendors supplied more of the capital. He sees today’s capital structures as cleaner, but GPUs may be less durable assets than fiber, which can remain usable for decades.
- Mike Volpi says GPU useful lives may outlast early estimates because AI software keeps older chips productive, but current scarcity makes that hard to judge. He frames the key economics as token revenue per watt, with newer generations converting electricity into revenue more efficiently.
- Mike Volpi says AI infrastructure works best when designed as one system, from chips and networking through the data center. He sees Google’s TPU architecture as the strongest example today, with NVIDIA moving toward the same rack- or data-center-scale approach.
- Mike Volpi says AI data-center traffic is more predictable and consistently utilized than traditional internet traffic, weakening the case for statistical packet multiplexing. He expects an opportunity for cheaper, purpose-built switching architectures, potentially using optical circuits, time division, or a combination.
Big Tech (4)
- Mike Volpi says Cisco’s acquisition strategy accepted failures and relied on deal volume to capture a few exceptional returns. Acquisitions supplied about half of Cisco revenue by 2000, and the company generally kept each purchase below 4 or 5 percent of its market capitalization.
- Mike Volpi says Cisco’s open networking protocols made acquired products easy to add to its sales portfolio, often with little more than a rebrand. He contrasts that integration advantage with AI acquisitions, while arguing NVIDIA can take risks because its market position gives it unusual optionality.
- Mike Volpi says Cisco made frequent acquisitions manageable with a small deal team and a centralized integration group that enforced repeatable processes. Small deals eventually became immaterial as Cisco grew, while larger acquisitions proved harder to integrate and sometimes failed.
- Mike Volpi attributes Cisco’s dot-com-era shock to customers overordering against expected cutbacks, followed by cancellations that left Cisco carrying supply-chain risk. Orders fell to roughly one quarter of their prior level, the company missed a quarter by 35 to 40 percent, and its share price fell from the $80s to $9 in six months.
Startups (1)
- Mike Volpi says boards weighing a sale should assess the founder’s appetite to keep building and whether the company could grow tenfold, not merely double. He encourages startup CEOs to keep relationships warm with competitors and potential acquirers, including through regular informal meetings.
Chips (2)
- Mike Volpi expects chip designs to diversify alongside model architectures, making hardware-software co-design more important. Reasoning workloads increase demand for memory bandwidth and large KV caches, which he says could favor 3D DRAM and hybrid copper bonding; Cerebras loses speed when a model spills beyond on-chip SRAM.
- Mike Volpi sees optical links as useful for rack-scale bandwidth and simpler cabling, but warns that heat makes optics difficult inside a chip module. He prefers copper where it can meet the need and says optical circuit switches that take about a minute to reconfigure are too slow.
VC (1)
- Mike Volpi says he retired in 2023 but returned to investing through Anabi Capital because AI demands systems-level thinking across the technology stack. He calls the current period more intellectually demanding and more interesting than the 1990s internet boom.
Why PMs are suddenly valuable again | Tulsee Doshi (Head of Product, Gemini) • Nov 8
- Tulsee Doshi says safe deployment includes monitoring models’ chain of thought for misalignment and intervening when needed. She also described Gemini work with cyber defenders and Wiz to find and patch vulnerabilities, including one in a hospital system.
Also discussed on this episode: (24)
Models (9)
- Tulsee Doshi oversees Google model families spanning video and image generation and editing, music, open models, and audio tasks including dialogue, speech, translation, and audio understanding.
- Tulsee Doshi says model development is monitored scientifically, but outcomes remain partly unpredictable. PMs need to notice where a model surprises users and turn those strengths into useful products.
- Tulsee Doshi says model products need different interfaces for different users: broad access for Search, specialized tools for power users, and new formats such as Flow and NotebookLM. She also treats a model’s communication style, transparency, and follow-up questions as part of its UX.
- Tulsee Doshi looks for PMs who use models daily, form opinions about their behavior, and stress-test them themselves. Strong candidates can inspect data, build evaluations, adapt quickly, and revisit plans as the field changes.
- Tulsee Doshi recommends starting model evaluations with a small set of prompts and judging outputs yourself before scaling. She says even a 20-prompt test can reveal differences between models and clarify what good performance means.
- Tulsee Doshi says evaluations must account for the judge, serving setup, filters, and production mitigations, not just the model. Audio tests also need to assess voice naturalness, tone, and inflection alongside spoken content.
- Tulsee Doshi advises testing models on tasks you care about, such as writing, visual generation, or financial analysis. Familiar tasks make it easier to notice where a model improves and where its results still fall short.
- Tulsee Doshi’s 60/20/20 rule reserves most of a product for what works now, another share for capabilities that nearly work, and the remainder for promising model behavior that could unlock a stronger experience. The mix lets products ship today and improve as models advance.
- Tulsee Doshi defines a model harness as its operating environment: system instructions, tools, skills, and context. She warns that old harnesses can constrain improved models, so teams should retest and remove assumptions that no longer help.
Big Tech (3)
- Tulsee Doshi says Google intends to compete at the frontier while using its full stack, from hardware and models to products, to serve users with different cost and capability needs. She cited 14 Google products with more than a billion users, while noting she should verify the number.
- Tulsee Doshi says Google wants its data to power useful AI experiences but acknowledged more work remains. She pointed to uncertainty about where and how to meet users, as outside assistants already connect to Gmail, Calendar, and Docs.
- Tulsee Doshi urged users to try Gemini, Argon, Gboard’s Rambler feature, and Google’s audio and Omni models, then send feedback through private or public channels. She said user feedback helps the teams improve their products.
Safety (2)
- Tulsee Doshi’s optimism about AI safety depends on people continuing to worry, question how models are built, and build mitigations deliberately. She sees sustained scrutiny as part of the path to safer deployment.
- Tulsee Doshi says Google replaced the six-tone Fitzpatrick scale in some evaluations with Professor Monk’s 10-tone scale, which better represented global skin-tone diversity. The work informed changes to Pixel camera and image-generation evaluation.
Startups (1)
- Tulsee Doshi argues that PMs become more valuable when building gets easy: they supply taste, identify worthwhile problems, and turn fast-moving work into a coherent direction. Without that clarity, speed can create chaos.
Agents (1)
- Tulsee Doshi’s Stanford research with Michael Bernstein organized crowdsourced workers into temporary “flash teams” matched to tasks and skills. She sees the same coordination principles applying to systems of AI subagents.
Enterprise (2)
- Tulsee Doshi’s team shares internal AI skills and runs workshops to build PM confidence with tools and data. She said the team planned a two-day November workshop, and argued that people need protected time to learn before the tools can accelerate their work.
- Tulsee Doshi sees AI-generated documents as useful for gathering current usage, metrics, and feedback after a launch; people should contribute the insight while models gather the data. AI has also expanded PM work into prototyping and data analysis, beyond writing requirements.
Adoption (1)
- Tulsee Doshi recommends asking whether AI can handle a task before doing it yourself, especially when the task recurs. One successful use can build confidence and prompt people to create and share reusable workflows.
Labor (1)
- Tulsee Doshi says heavy workloads can cause burnout through chaos and pointless tasks, not hours alone. She hopes AI can remove grunt work, while emphasizing sustainable workloads and work that matches each PM’s motivations.
Health (1)
