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.
