Introducing Cosmos: the Unified Agents Platform for software teams. Orchestrate a fleet of agents across your entire software development lifecycle, as a single organizational system instead of disconnected workers. It's changed how our own engineering team works, with throughput up 3x.

Claude Fable 5 has been suspended following a US government directive. Details here: x.com/AnthropicAI/st…. We've removed Fable 5 from our model picker for now. Any new and existing agent sessions in Cosmos that were pre-configured to use Fable 5 will now fallback to Opus 4.8 (at Opus 4.8 pricing). No action is needed unless you choose to switch to another model. All other models remain fully accessible.

@augmentcode how many credits do claude fable 5 cost?

Fable 5 is now available to Augment Code users. At ~2x the cost of Opus 4.7, Fable 5 is a premium option for long, multi-step engineering work. Try Fable 5 today in Cosmos, our unified agent platform, to fully experience the power of the most advanced model on the market.

Fable 5 is built for long-horizon work: investigations, multi-step changes, and end-to-end tasks that normally take hours. You’ll see the biggest lift when you point it at your hardest, most ambiguous engineering work. If you try Fable 5, let us know: we’re eager to hear how you use it and where you find the most value with this new model family.

With models like Fable 5, model routing is more important than ever. We’ll be adding Fable 5 to our model router, Prism, soon. Prism routes each turn to the best-fit model and is cache-aware, so teams can keep frontier-level quality while cutting cost. In our internal benchmarks, Prism delivered up to 30% lower cost per task at no difference in quality.

The bigger unlock is Fable 5 running in our unified agent platform, Cosmos. Pull context from your tools and run across the SDLC (triage → spec → implement → review → test → deploy). Instead of “one prompt, one answer,” you get background workflows with triggers + durable memory: and engineers step in only when judgment is needed.

TL;DR: Fable 5 isn’t the right-sized model for every task, but when quality and depth matter (review, architecture, long-running changes), the lift is impressive. Here’s how it stacks up vs Opus 4.8 + GPT‑5.5

We're all experiencing the moving bar of "being AI native". How do we navgiate it? Watch the full episode with @CircleCI's @z00b here: youtu.be/2cGdwowJiSw?si…

TODAY: the first live look at Cosmos, the Unified Agents Platform. Join us at 10am PT to hear from our VP of Engineering on why we built Cosmos, plus a live build and what we’ve learned running cloud agents across our own engineering org. Sign up to join live or catch the recording: watch.getcontrast.io/register/augme…

Live this Friday, June 5 at 10 AM PT: the first look at Cosmos, our new Unified Agents Platform. Your engineers are shipping more code than ever, but your org doesn't feel 10x more productive. Adding more agents won't fix that. You need a system. Join @VinayPerneti (VP of Eng), Rich Hankins (Founding Engineer), and Sharath Rao (Solutions Architect) to see what changes when agents share context and memory across the team. Sign up to join live or get the recording: watch.getcontrast.io/register/augme…

See it live this Friday, June 5 at 10am PT. Full walkthrough of Cosmos, plus how our own team at Augment uses it. Try Cosmos today: cosmos.augmentcode.com Register here: watch.getcontrast.io/register/augme…

Cosmos runs in your environment or ours, supports the models you choose, and provides the observability, auditability, and human oversight required to deploy agents at scale. Learn more: augmentcode.com/blog/cosmos-th…
