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

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

Devin's testing capability has improved with GPT-6 Astra, enabling it to autonomously verify its own work, which reduces the amount of code engineers need to review, directly accelerating their shipping process.

Summary B

GPT-6 Astra enables Devin to autonomously test code with higher accuracy, reducing engineers' manual review burden by 20–30%. This lets teams deploy faster with greater confidence in autonomous agent outputs, but requires adapting validation workflows to handle AI-generated test cases at scale.
