Developer-relevant changes include mid-conversation system messages and a lower prompt-cache minimum of 1,024 tokens.
The Age of Async Agents — Cognition's Walden Yan & OpenInspect's Cole Murray
Latent Space5d agoCommentaryLatent Space interviews Cognition's Walden Yan and OpenInspect's Cole Murray on the rise of async coding agents. The discussion centers on Devin-related workflows, including 80% Devin commits, spec-to-PR development, full VMs, agent memory, and PMs shipping code. The key theme is not a model release, but a shift toward agents that can work asynchronously inside more complete software delivery loops.

The project has also split AI-generated bug reports into a new SQLite Bug Forum, where D. Richard Hipp is responding with commits.
