A new tool called Delta has entered public beta, offering a multiplayer workspace where teams write code alongside AI agents and review the results without relying on traditional pull requests. The company behind it says it has already disabled pull requests on its own repository, running all internal collaboration through Delta instead. The tool is available on macOS, Linux, Windows, and via browser, including mobile access to ongoing conversation threads.

A new benchmark comparing OpenAI's GPT-5.6 Luna and GPT-6 Astra on code review found Luna verified 69 bugs across 50 pull requests versus Astra's 92, while costing roughly 28 times less per review. Luna also produced more false positives, with 24 of 93 flagged issues failing verification compared to Astra's 4 of 96, and it caught fewer security-related bugs.

A software developer shares an anecdotal pattern from years of code reviews: peers rarely object to map or filter functions, but frequently flag reduce as hard to read. The developer notes reduce appears far less often in codebases than similar array methods, despite personally preferring it.

Early benchmark testing shows OpenAI's GPT-6 Astra model identifies about 4% more actionable bugs than GPT-5.6 Sol and 22% more than Opus 5 in code review evaluations. The advantage widens significantly on harder cross-file reviews, where Astra beats Sol by 20% and Opus 5 by 33%, suggesting stronger ability to trace how a change in one file affects code elsewhere.
