How We Build and Deliver Reasoning Data

  1. Construct: We select tasks, write expert prompts, and generate step-by-step CoT traces
  2. Verify: Each output is scored, unit-tested, and run through structured self-reflection
  3. Deliver:
You receive scoped data packs tailored to your model’s target domains and evals
End-to-end: task creation → human chain-of-thought → unit test → self-reflective verification.
