c8data

c8data is an installable Python package for instruction-driven synthetic data generation inspired by Meta's AutoData / Agentic Self-Instruct loop.

It creates candidate examples, verifies their quality, tests them against weak and strong solvers, judges the solver outputs with a rubric, and only accepts examples that create a meaningful weak-vs-strong performance gap.

Documentation

• Setup guide — install, API keys, model configuration
• Usage guide — API reference, sources, output format, examples

Quick start

uv add c8data
export C8DATA_API_KEY="your-api-key"

from c8data import AutoDataGenerator

gen = AutoDataGenerator(output_dir="./data/out")
results = gen.run(source="paper.md")

print(results[0].accepted)
print(results[0].output_path)

See the setup guide for full configuration options and the usage guide for custom instructions, batch runs, and output format.
