Fangcun independent report 2610.35671v1, Oct 4–25 2026 hosted API evaluations; source Table A.1 resolves all seven full model names. Temperature 1, top_p 0.95, maximum reasoning effort unless explicitly overridden; GLM 5.3 rubric judge. API/format failures excluded according to source; not locally deployed weights or uncensored variants. Fixed submitted coding workflows evaluated on 165 held-out Rust problems. Gemini original workflow scored 0 due output-format mismatch; published 51.52 is after post-hoc repair, retained as distinct workflow. Bootstrap difference panel is not another independent benchmark. Metric: Problems passed (%).
