Cuarzo-100K v2

Summary

A dataset of 99,683 bidirectional deterministically verified Python-to-human-language pairs across English, Spanish, French, and Mandarin Chinese, generated by Aether (Cuarzo AI's proprietary engine for generating deterministic paired data between code and human language). Each record contains original Python from StarCoderData, structured natural language representations in all four languages, and roundtrip-validated Python regenerated from each language representation with AST equality and compilation checks. The v2 release adds Mandarin Chinese as a full fourth language surface and expands the verification schema to per-language roundtrip checks across all four surfaces.

Only records passing every check across all four surfaces are included. Contact: hello@cuarzoai.com. The HF page returned 401 on direct fetch; info gathered from search results and HF post.
