Cursor's Composer 2.5, built on a Kimi foundation, scores near Opus 4.7 and GPT-5.5 on benchmarks at a fraction of the cost, but user reports and updated agent-focused benchmarks show mixed real-world performance.
Eric Bahn says most VCs are not using AI tools seriously; they haven't produced real software with tools like Cursor and still rely on pen and paper, creating a backward industry despite preaching AI adoption.
Eric Bahn states his firm, Hustle Fund, uses AI tools to automate deal assessment and data outreach, with his co-founders shipping code daily via Cursor to stay lean as a small AUM fund.
Eric Bahn praises Cursor's sophistication for coding, saying its feedback on inefficient code feels like senior engineer guidance and declares AGI has essentially arrived within the coding domain.
Fable 5 scored 72.9% on Cursor Bench, eight points above the previous best, but is more expensive on that cost-performance test.
Ben describes Grok Build's CLI as a polished, fast harness clearly inspired by Cursor and Claude Code, benefiting from XAI's engineering discipline.
Cursor has processed a trillion tokens, creating a data advantage public coding companies could challenge only by running new AI products at break-even.
Nathaniel Whittemore reports Cursor (now SpaceX AI) began work in April on a general-purpose agent called SAND, designed as a personal assistant for office tasks like email and spreadsheets.
Michael Kim notes early-stage investors in hot companies like Cursor or 11 Labs are encouraged to sell secondaries, but late-stage lead investors face negative signal risk if they sell.
Cursor's Composer 2.5 model ranks third on the Artificial Analysis coding agent index and operates at 10 to 60 times lower cost than high-effort Opus 47 and GPT 55 settings.
Nathaniel Whittemore points out that external benchmarks, such as Cursor Bench and Max Effort, indicate Sonnet 5 can be more expensive than Opus 4.8 or even Fable per task due to generating significantly more output tokens.
XAI proactively partnered with T3 Code, with Milo initiating outreach, to integrate the Grok CLI using the Agent Client Protocol (ACP), enabling Composer 2.5 model access outside Cursor's harness.
Current online learning models, like the Cursor tab model predicting user-accepted edits, require learning the same objective across hundreds of millions of daily requests to be effective.
xAI introduced a goals primitive in Grok for long-horizon coding tasks, deploying sub-agents and orchestrating the process, which marks a new UX primitive and showcases its Cursor partnership.
Theo was an investor in Cursor, which SpaceX AI acquired in a $60 billion all-stock deal. Theo stands to make between $50,000 and $2.5 million from the acquisition.
Ben notes SpaceX AI, combining XAI and SpaceX, aims to overcome its lack of data and researchers by acquiring Cursor, despite having vast GPU warehouses. This positions it as a major AI lab.
Cursor is launching 'Origin,' a new code review platform built by its acquired company, Graphite, designed to efficiently fork large monorepos. Cursor aims to be a comprehensive enterprise software development suite, including local IDE, cloud agents, and code hosting.
Cursor's upcoming model, possibly Composer 3, will be pre-trained from scratch, aiming for general intelligence beyond code, with a claimed size of 1.5 trillion parameters. This marks a significant leap from previous Composer models based on fine-tuned open-weight models.
Ben predicts Cursor's new model will be branded as a Grok variant and exclusively available via XAI APIs, potentially with GPT-4-like pricing. Theo expects the model will likely avoid third-party cloud platforms like Bedrock or GCP.
SpaceX's stock surged from $135 to over $200 per share in pre-market trading after announcing its IPO, adding roughly $1 trillion in market value and enabling a $60 billion stock-based acquisition of the AI startup Cursor.
SpaceX is acquiring AI code tool Cursor at a $60 billion valuation, a move Bill Aamann argues is strategically accretive due to SpaceX's high market value attracting talent and enabling cheap acquisitions.
Brian Xiao outlined operational impacts: US companies will need ID verification for API billing, affecting downstream services like Cursor and Harvey. Frontier labs like OpenAI and Google DeepMind now lack incentives to release mythos-caliber models.
Jason Calacanis says SpaceX plans to acquire Cursor for $60 billion in stock, giving Cursor access to SpaceX’s massive compute resources for model development.
Jason Calacanis notes SpaceX’s market cap hit $2.88 trillion after its IPO, making it the fourth most valuable US company. He calculates the Cursor acquisition at a 20x revenue multiple.
Ryan Daniels explains that Cursor once accounted for 40-50% of Anthropic’s total revenue, but Anthropic’s launch of Claude Code forced Cursor to build its own model, leading to the SpaceX deal.
Jason Calacanis cites Claude Code’s rumored $2.5 billion revenue run rate and Cursor’s $4 billion run rate, predicting the AI coding market will reach $100 billion soon.
Jason Calacanis believes SpaceX's acquisition of Cursor is cheap at a 15x revenue multiple, citing Cursor's $4 billion run rate and solving its compute and model dependency problems.
SpaceX acquired Cursor for $60 billion; Cursor had a $4 billion run rate and was growing 7x year-over-year. Its Composer 2.5 model matches Opus 4.7/GPT 5.5 performance at a tenth of the cost.
Cursor engineer Nick Dobos teased a new from-scratch model, same size as Opus and GPT 5.5, using 10-20x more compute than Composer, aimed for general intelligence.
David Bennett states SpaceX's $60 billion acquisition of AI coding startup Cursor will be paid entirely with freshly valued SpaceX shares, not cash, as the deal closes by end-September.
