Frontier Traces SFT

A merged SFT dataset of almost 40k examples drawn from 11 frontier-model trace datasets.

Schema

Each row has two columns:

  • messages list of {role, content} dicts (standard chat format).
  • source_model string identifying the originating model.

Sources

Notes

  • The crownelius/Opus-4.6-Reasoning-2100x dataset was converted from columnar format (problem, thinking, solution) to chat messages with <think> tags.
