It's worth noting that our team was working with Glint-Research to collect as much fable data as possible.
These are just the anonymized raw traces of both of our teams combined. This means that Glint-Research/Fable-5-traces was created from formatting and splitting up this same dataset. If you use one for your tune, don't use the other (it's the same exact data).

Dataset Description
This dataset contains 5,000 agentic coding and reasoning traces generated by the new Fable 5.1 model using max reasoning effort.
It holds almost 150,000,000 tokens of step-by-step chain-of-thought programming across multiple complex domains.
It has also been deduplicated and filtered to remove low-quality traces, keeping only high-quality traces.
