Greptile uses GPT-6 Astra to test apps beyond code review
Original title: Greptile takes bug detection beyond code review with GPT-6 Astra
The startup also wires its knowledge base to Codex over MCP and cites Daybreak for customer defenses.
OpenAI published a customer story on startup Greptile, whose agents review code and use GPT-6 Astra computer use to run apps and test pull requests like a user. CEO Daksh Gupta also describes Daybreak for customer defenses and a knowledge base exposed to Codex through an MCP server. He says fewer AI-code reverts follow that context, and he looks to Ultrafast to speed development. The post reports no new model launch or security incident.
Unconfirmed: Usage and revert claims are Gupta’s statements in OpenAI’s customer story.
- Greptile is a North American technology startup using the API and Codex.
- Gupta says thousands of customers connected Codex to the knowledge base.
- The team tracks how often AI-generated code is reverted.
- Ultrafast is framed as a speed lever, not a released product in this post.
