Dataset Description

This dataset contains 1,000 agentic coding and max reasoning multi-turn, high-quality traces generated by Fable 5.1 max recently (leaked version of fable 5.5).

It holds around 75,000,000 training-ready, reasoning-heavy tokens of step-by-step chain-of-thought programming across multiple complex domains.

It has also been deduplicated and heavily filtered to remove low-quality traces, keeping only high-quality traces.
