## Differences with Fable 5 (based on what we know)
I want to preface by saying I'm writing this before the official Fable 5 re-release, and this is only the best information I have available - things may be subject to change.
Based on the official Anthropic docs, there are 6 core differences between Fable and all other Claude models:
1. Run Time
Every Claude model before Fable 5 worked in relatively short bursts.
Claude Fable 5 is meant to sustain output over extended periods to complete multi-day, goal-directed tasks.
This is one of the biggest shifts. Fable 5 is meant for fully autonomous work (paired with /goal or /loop).
2. It Gets Things Right First Time
One of the most reported early observations from people using Fable 5 is how rarely they need to iterate. Early testers reported single-pass implementations of systems that previously took days of iteration.
