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 Gemini 3.1 Pro (94) and Claude Opus 4.7 (94). There is meaningful separation between the top models, suggesting genuine performance differences.
The best open-weight option is GLM-5.1 (ranked #10 with a score of 84). While proprietary models lead, open-weight options are within striking distance for teams willing to trade a few points of performance for full model control.

The top model is Claude Mythos Preview by Anthropic with a provisional score of 99.
The best open-weight model is GLM-5.1 at position #10.
109 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.
