Cognition hits $48B valuation as AI coding race widens; Devin adds GPT-6 Astra for automated code testing

Devin maker Cognition raised $2B at a $48B valuation led by a16z, Accel, and Founders Fund with $900M annualized revenue, while an OpenAI case study details how GPT-6 Astra now automates testing across Devin's cloud agent, CLI, and desktop products.

Cognition, the startup behind autonomous software engineer Devin, raised $2 billion at a $48 billion valuation just four months after a $26 billion round, with backing from Andreessen Horowitz, Accel, Founders Fund, General Catalyst, and Avenir — a signal investors see room for multiple winners in AI coding rather than a winner-take-all market. Annualized run-rate revenue grew from $492 million to $900 million since May, with a projected $4-5 billion by the end of 2026, though compute costs from a leased Nvidia cluster could push total 2026 cash burn to $800 million. The company, founded by Scott Wu, serves customers including Mercedes-Benz, NASA, Goldman Sachs, and Citi, and is training its own model to reduce reliance on OpenAI and Anthropic. Separately, an OpenAI customer case study (2026-09-11) describes how Cognition integrates GPT-6 Astra across Devin's cloud agent, CLI, and desktop products to automate testing and provide evidence for code review: in one example, Devin used Astra to test the iPhone game Otter Run, returning a simulator recording plus a report of passed checks and untested areas. Co-founder Walden Yan said Astra's ability to test and prove work as expected could reduce manual code review, and the team also uses it to fix customer-reported bugs from screenshots and return verification screenshots faster.

• Cognition raised $2B at a $48B valuation led by Andreessen Horowitz, Accel, Founders Fund, General Catalyst, and Avenir — four months after a $26B round (TechCrunch, 2026-09-08).
• Annualized run-rate revenue grew from $492M to $900M since May; $4-5B projected by end of 2026.
• Compute costs from a leased Nvidia cluster could push total 2026 cash burn to $800M.
• Customers include Mercedes-Benz, NASA, Goldman Sachs, and Citi; company founded by Scott Wu.
• Cognition is training its own model to cut reliance on OpenAI and Anthropic, even as an OpenAI case study (2026-09-11) shows it uses GPT-6 Astra across Devin's cloud agent, CLI, and desktop products.
• In a case-study example, Devin used Astra to test the iPhone game Otter Run, producing a simulator recording and a report of passed checks and untested areas.
• Co-founder Walden Yan says Astra's automated testing could reduce manual code review; the team also uses it to fix customer-reported bugs from screenshots and return verification screenshots.
• The funding signals VCs believe the AI coding market is not winner-take-all.
