What happened
OpenAI published a customer story on Greptile, an AI code-review agent startup, describing how it uses GPT-6 Astra's computer use to run pull-request apps in a browser — for example, resizing the viewport to iPhone dimensions to catch a button that disappears — alongside the Daybreak security product and Codex, which reads Greptile's indexed codebase documentation through an MCP server. The text is truncated and contains no pricing, availability dates, model benchmarks, or independent measurements; CEO Daksh Gupta's quotes are the only source of claims.
Why it matters
This is a vendor case study, not a product launch or benchmark, so there is nothing here to migrate to or budget for yet. The one concrete idea worth borrowing is the pattern: expose your codebase documentation to a coding agent via an MCP server, and use computer-use agents to exercise the running app (viewport resizing, simulated clicks) rather than only reading the diff — useful if you are deciding how much of QA to automate versus keep manual.
Discussion angle
Would you trust a computer-use agent clicking through your app on every PR? Discuss where simulated-user testing breaks down (auth, payments, flaky states) and whether exposing internal codebase docs via an MCP server is worth the access risk.
