What the data shows

  • Top by average across all benchmarks: gpt oss safeguard 20b MLX MXFP4 (73.6 %), Qwen3.5 9B MLX 4bit (71.7 %), gemma 4 12b coder fable5 composer2.5 8bit (71.5 %).
  • Best per category: Knowledge: gpt oss safeguard 20b MLX MXFP4 (68.9 %) · Reasoning: gemma 4 12b coder fable5 composer2.5 8bit (84.0 %) · Math: gpt oss safeguard 20b MLX MXFP4 (90.0 %) · Coding: MLX Qwopus3.5 27B v3 4bit (71.1 %) · Safety: Qwen3.5 9B MLX 4bit (92.0 %)
  • The base Qwen3.5 9B (4-bit) scores 71.7%. 6 community distills of the same 9B base ("Claude", "Gemini" or "GLM" distills, Qwopus) land at only 34.0–40.7%. Part of the gap may come from the test format: short answer limits penalize models that "think" at length before answering.
  • Bigger is not automatically better: 4-bit Qwen3.5 9B clearly beats Gemma 3 27B and Qwen3.6 35B A3B at 2-bit quantization, and Qwopus3.5 27B at 4-bit, in this test.

All results

Accuracy in percent. Avg = mean of benchmark scores; categories = mean of their benchmarks. "Questions" = all questions the model answered, "min." = smallest sample in any one benchmark. All individual scores as CSV

How we measured

  • Hardware: one Mac mini M4 with 32GB of unified memory. All runs local, no cloud.
  • Runtime: oMLX, a local OpenAI-compatible server for MLX models, queried through chat completions.
  • Settings: temperature 0 (deterministic), short answer limits for multiple-choice questions (10 tokens) and longer ones for math and code (up to 512 tokens).
  • Scoring: accuracy = correct answers divided by questions asked, per benchmark.
  • Benchmarks (16): MMLU, JMMLU, KMMLU, MMLU-Pro, CMMLU, HellaSwag, WinoGrande, ARC-C, TruthfulQA, GSM8K, MathQA, MBPP, HumanEval, LiveCode, BBQ, Safety.
  • Models: MLX quantizations publicly available on Hugging Face; quantization is listed under each model name. Private fine-tunes are excluded.

Limits of the data

  • Sample sizes differ: 244 of 437 measurement cells rest on fewer than 100 questions. At 30 questions the statistical uncertainty is roughly ±15 to 18 percentage points. Small gaps between models are therefore no proof of a real difference.
  • The scores are not comparable with vendor-reported results: different prompts, subsets, quantization and answer limits.
  • We measured answer quality, not speed. Tokens per second and memory needs are covered by the RAM calculator and the model articles.
  • Models with incomplete coverage are listed without a rank at the end of the table.
