Fable-5 SFT Traces
Author / maintainer: kelexine (github.com/kelexine)
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
of collection.
The dataset supports three fine-tuning shapes off a single JSONL with no

Fable 5 FLAMINGO Research Task Traces
This dataset is a small corpus of Claude Fable 5 / Claude Code traces from
real FLAMINGO cosmology-analysis work. It is organized by explicit research task
so the Dataset Viewer makes clear what was being operated on and how the agent
took actions.
Start with the task_index config. It lists each task, the exact original user
prompt when available, the model setup, what Claude did, the raw trace file, and
the corresponding viewer configs.… See the full description on the dataset page: https://huggingface.co/datasets/licongxu/fable5-flamingo-research-trace.Complete-FABLE.5-traces-2M
