Cognition helps Devin test its own work with GPT‑6 Astra

Cognition, which builds the coding agent Devin, describes using OpenAI's GPT-6 Astra to return evidence of software behavior alongside code changes. In the published customer account, Devin tests an iPhone game in a simulator and provides a recording plus a report separating completed checks from areas left untested.

Those outputs give an engineer something concrete to inspect: what the application did and how much testing covered. The page states the goal as helping engineers review less code and ship more. The account describes the testing workflow and its intended benefit, without measuring a reduction in review time.
