Each dot is a model. Up = higher score, left = smaller (easier to run locally). The dashed line marks the efficiency frontier — the best score you can get at each size or smaller.
  • Qwen3.6 27B, 28B, score 70.3 — on the efficiency frontier (best score at its size or smaller).
  • DeepSeek V4 Flash, 158B, score 70.6 — on the efficiency frontier (best score at its size or smaller).
  • MiniMax M3, 427B, score 74.5 — on the efficiency frontier (best score at its size or smaller).
  • GLM 5.2, 753B, score 78.6 — on the efficiency frontier (best score at its size or smaller).
  • DeepSeek V4 Pro, 862B, score 82.7 — on the efficiency frontier (best score at its size or smaller).
  • Kimi K2.7 Code, 1.1T, score 82.8 — on the efficiency frontier (best score at its size or smaller).

LiveBench Reasoning: frequently asked questions

What is the best open LLM on LiveBench Reasoning?
Kimi K2.7 Code is the top open model on LiveBench Reasoning, scoring 82.8. Among all models tested — including proprietary ones — it ranks #22. The top model overall is GPT 5.6 Sol Max (OpenAI) at 91.7.
What's the best LiveBench Reasoning model you can run on a 24 GB GPU?
Qwen3.6 27B is the highest-scoring open model that fits in 24 GB at 4-bit quantization (about 15 GB), scoring 70.3 on LiveBench Reasoning.
Can open models match proprietary models on LiveBench Reasoning?
Not quite on LiveBench Reasoning: the strongest proprietary model (GPT 5.6 Sol Max) scores 91.7, ahead of the best open model (Kimi K2.7 Code) at 82.8 — but you can run the open one yourself.
