More agents ≠ engineering transformation. Meet Cosmos, the OS for agentic software development.

Your PR sat for three days. CI was red, comments piled up — and your reviewer didn't have the confidence to hit approve. A fleet of agents performs multiple rounds of review, fixes the CI, the comments, the conflicts, then hands your reviewer a deep review briefing and end-to-end evidence. Humans still approve and merge 👇

Quick start: a software factory in Cosmos is two screens and one prompt. 1. Connect your repo 2. Create an environment 3. Describe the factory you want Advisor picks the experts, writes the configs, applies them, and asks you when it needs a decision.

The best part of an agent that runs in the cloud isn't the speed. It's that you can walk away. Cosmos notifies you the moment it needs you. Everything else, it handles.

Watch a PM and an engineer collaborate on a PRD — with their agents, without leaving Cosmos. A PM drafts it with her agent. An engineer opens the same file, has his own agent review it, leaves a comment. Her agent answers it and updates the doc. One filesystem. Both people. Both agents.

Claude Fable 5.1 is now available in our model picker! We're starting off with the same use cases as Fable 5 - extremely long, multi-step tasks that require deep reasoning - and we're increasingly pushing the model to complete tasks that can run unattended. Try it today in Cosmos: augmentcode.com

Opus 5 is live in Augment Code. In our internal evals it scored higher than Opus 4.8 on correctness, completeness, and code reuse. We trust it enough that we're upgrading one of our Cosmos code review experts that reviews all our code to Opus 5: near-Fable review quality at a lower price. Try it in Cosmos today!

Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.
