claude-fable-5 Agent Traces
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).

A cleaned, anonymised, schema-normalised derivative of
Kelexine/Fable-5-traces
— agentic traces from Fable-5 (claude-fable-5), the model now publicly
known as Claude Mythos — Anthropic's top-of-family frontier model at time

Fable 5 Claude Code Traces
A full, scrubbed release of Fable 5 Claude Code session traces for researchers studying real coding-agent behavior: multi-turn prompts, assistant responses, tool calls, command output, retries, and session-level workflow metadata.
This release keeps the full package intact: 18 sessions, 9,497 JSONL events, 0 excluded rows, and 0 quarantine files. The traces are preserved in the native agent-event format so they can be inspected in Hugging Face Agent… See the full description on the dataset page: https://huggingface.co/datasets/AlinCiocan/fable-5-claude-code-traces.fable-5-coding-and-debugging-traces

🍄 Super Fable Bros. — Claude Fable 5.1 Agent Trajectory
The complete, unedited coding-agent session in which Claude Fable 5.1 (claude-fable-5-1 — mind the minor version, the point-one is the whole point) one-shotted a
playable Super Mario Bros. World 1-1 remake in a single HTML file — zero dependencies,
zero external assets, WebAudio chiptune synth, hand-encoded pixel sprites.

The raw trace files live in sessions/*.jsonl. Cache files, paste-cache files, shell history, and merged COT training exports are intentionally omitted so Hugging Face Datasets can load the repo through the agent-traces path.

For training on this dataset I recommend using the teich package to convert to openai style chats. It parses and filters out things like hitting limits and model switches, etc. As well as knows the exact tool-schemas and descriptions for the tools used.
I encourage everyone to please upload their fable-5 traces from whatever harness they may have used. This is all valuable data and we need to pool it together to make something meaningful :)
