Fable 5 brings a new level of capability to complex software engineering work.
We've found it performs best for:
- Code review where catching subtle issues matters
- PR authoring and implementation support
- Large-project planning and architecture reasoning
- Long-running, multi-step technical tasks
- High-stakes engineering work where quality matters more than cost

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.
