Compare model intelligence and coding benchmarks
Compare models using published benchmark scores. Higher scores are better. Each chart uses one benchmark and source version; these are current comparisons, not scores recorded at launch. Ranking pairs each model’s standard and thinking evaluations on one row, Value plots score against the output token rate, and Generations tracks each family release by release. Thinking evaluations are labeled with their published settings, and evaluation effort can affect scores.
Artificial Analysis Intelligence Index
Source version not published · 24 models scored
Using cached Artificial Analysis scores. Recent models and evaluations may be missing.
Which model scores highest, and what does thinking add?
Source: Artificial Analysis. Missing scores mean no verified matching result is available here for this version; they do not mean the model was never evaluated. Token rates are NanoGPT standard catalogue rates.

Base text-token rates. Long-context pricing, tool charges, service tiers, and provider selection can change the total. Cache creation is charged when writing tokens to the cache; cache read applies when reusing them. The default cache duration applies unless labeled otherwise. Unsupported cache rates are marked unavailable.
Estimated query cost combines your input-token count with the model’s average output, rounded to whole tokens, at current standard rates. It assumes uncached input and excludes tool charges. This is an estimate for that workload, not a measured average total bill.

Claude Haiku 4.5
claude-haiku-4-5-20251001Claude Haiku 4.5 matches Sonnet 4's coding quality while running about twice as fast at roughly one-third the price, making it ideal for low-latency chat assistants, support bots, and pair programming. Pair it with Sonnet 4.5 to plan complex work and fan out execution across parallel Haiku workers.
