BenchLM.ai now distinguishes provisional overall ranking from verified overall ranking. The provisional score is a normalized weighted average across 8 benchmark categories: agentic (22%), coding (20%), reasoning (17%), knowledge (12%), multimodal & grounded (12%), multilingual (7%), instruction following (5%), and math (5%), using non-generated benchmark coverage plus bounded external consensus calibration. The verified leaderboard is stricter and only counts sourced benchmark rows. Each score includes a confidence indicator (1-4 dots) based on how much sourced coverage supports it. Display-only benchmarks — including MMLU, OpenBookQA, HumanEval, FLTEval, BBH, LisanBench, and older AIME/HMMT variants — remain visible for context but do not affect ranking.
Unless noted otherwise, ranking surfaces on this page use BenchLM's provisional leaderboard lane rather than the stricter sourced-only verified leaderboard.
Bottom line: Claude Mythos Preview leads overall, but GPT-5.4 and Claude Opus 4.6 are within striking distance — and significantly cheaper.
According to BenchLM.ai, Claude Mythos Preview leads this ranking with a score of 99, followed by Claude Opus 4.8 (95) and Gemini 3.1 Pro (92). There is meaningful separation between the top models, suggesting genuine performance differences.
The best open-weight option is DeepSeek V4 Pro (Max) (ranked #12 with a score of 87). Proprietary models hold a clear advantage in this category, though open-weight options may suffice for less demanding use cases.

The top model is Claude Mythos Preview by Anthropic with a provisional score of 99.
The best open-weight model is DeepSeek V4 Pro (Max) at position #12.
119 models are included in this ranking.
The overall score is a weighted average across 8 benchmark categories. Agentic (22%), coding (20%), and reasoning (17%) carry the most weight. A 5-point gap in overall score is meaningful — it reflects consistent performance differences across multiple domains.
The overall score compresses 8 categories into one number. Two models with the same overall score can have very different strengths — one might lead coding while the other leads reasoning. Always check category scores for your specific use case.
