Greptile Says GPT-6 Astra Now Tests The App, Not Just The Code
OpenAI published a customer story about Greptile, a code review startup that pays for its API, and what its co-founder says GPT-6 Astra does once reading the code is not enough.
Transcript
Greptile says its code reviewer now operates the application. OpenAI says GPT six Astra automates the testing.
Greptile builds AI agents that review code with full context of the codebase. OpenAI says Astra's computer use now tests running applications.
Greptile's co-founder describes a button that vanishes on an iPhone. Astra starts a development server, resizes the window, and inspects it.
Greptile also says Daybreak strengthens customer security. It says thousands of customers connect OpenAI's Codex to its Knowledge Base through a Model Context Protocol server.
This is OpenAI's own customer story about a paying API customer. No result is measured and nothing is independently tested.

Every claim in this video comes from the top ranking coverage of this topic. The claims and where each one came from:
- Every narrated claim traces to this single first-party page, which is OpenAI's own marketing customer story about Greptile, a startup that pays for OpenAI's API, and which contains no benchmark, no percentage, no measured figure, and no independent testing. HOOK: 'Greptile says its code reviewer now operates the application' is supported by the article's opening sentence 'Greptile builds AI agents that review and test code changes with full context of the codebase' combined with 'For Daksh, that mission requires testing an application's behavior as well as reading its code'; the second hook sentence, 'OpenAI says GPT six Astra automates the testing', is supported by 'GPT-6 Astra's computer use gives Greptile a way to automate testing at scale', a claim made by OpenAI in its own customer story and not verified by us. SCENE 1: 'Greptile builds AI agents that review code with full codebase context' is a restatement of the article's opening sentence; 'OpenAI says Astra's computer use now tests running applications' is supported by the same computer use sentence plus 'For some of that testing, you need to actually run the application because reading the code alone might not reveal the problem.' This is OpenAI's and Greptile's description of their own product, not a tested result. SCENE 2: the vanishing button, the development server, the resized window, and the screen inspection all come from 'Daksh gives the example of a button that disappears when a website is viewed on an iPhone. With GPT-6 Astra, Greptile can start a development server for a pull request, resize the browser to an iPhone-sized viewport, and simulate a user moving through the application. The model's visual understanding lets it inspect the screen and spot the hidden button.' This is an illustrative example offered by Greptile's co-founder, not a documented test case. SCENE 3: 'Greptile also says Daybreak strengthens customer security' is supported by Daksh's quote 'With Daybreak, we're able to do this in a way that is very safe, and we can ensure that our customers have more sophisticated defense mechanisms than the adversaries have offense mechanisms.' 'It says thousands of customers connect Codex to its Knowledge Base through a Model Context Protocol server' is supported by 'Greptile's Knowledge Base indexes a company's codebase and documents how it works in a form people and agents can read', 'The company makes that documentation available to Codex through a Model Context Protocol (MCP) server', and 'thousands of customers have connected Codex to Greptile's knowledge base, according to Daksh', which is why the narration attributes the number to Greptile rather than stating it as fact. SCENE 4: the accountability claims are supported by the page itself, which is labelled a Startup customer story on OpenAI's own site listing API and Codex as the products used, attributes every quoted claim to Daksh Gupta, and reports no revert rate, no error rate, and no third party evaluation. The article also describes Daybreak and Ultrafast in forward-looking terms only, and the narration does not present either as a shipped, measured result.(OpenAI's own Startup customer story, published October 26, 2026, titled 'Greptile takes bug detection beyond code review with GPT-6 Astra', in which every claim is attributed to Greptile co-founder and CEO Daksh Gupta.)
