Local Qwen coder model ties Claude Opus 4.6 at 92.7 in DIY coding benchmark

A Redditor benchmarked two local models against Claude Opus 4.6 on three Python tasks (log analyzer, parallel job runner, toy interpreter), one attempt each, graded by 162 hidden tests plus a fixed code-review checklist, hard task weighted 3×.
Scores (out of 100):
- Claude Opus 4.6: 92.7 (162/162 hidden tests)
- Qwen3.8-Flash-Next "Coder" (local, Strata-pruned IQ1M GGUF): 92.7 (161/162)
- Qwen 3.8 27B Unsloth Q6: 87.0 (160/162)
Local models won the easy task (97/92 vs 88), Opus took the medium one, and Opus and the Coder tied at 92 on the hard interpreter. Qualitatively, Opus writes cleaner code while the local Coder crashed less on weird inputs.
Hardware: i5-14400, 48GB RAM, dual RTX 5060 Ti (32GB VRAM); the 27B Q6 runs at 50 tok/s, the Coder 60–65 tok/s. The author caveats single-run noise, AI-assisted grading (public rubrics), and small task size — but concludes the results were indistinguishable at this scale, which matters for skipping frontier subscriptions.
