Estimate a workload

$0.00
Excludes taxes, non-token charges, and tiered discounts.

34 providers list the identical $2 input rate, so price alone will not separate them — compare context limits, max output, and capabilities above.

Context limits also differ by provider, from 200K to 524.288K tokens. Compare the provider table above before choosing on price alone.

Benchmarks

Every result stays attached to its source, version, metric and harness. Scores from different versions are never merged, and the profile below plots each benchmark against its own population rather than on a shared scale.

Benchmark registry
Benchmark profile
Terminal-BenchTerminal-Bench 4.0 DeepSWEDeepSWE 1.1 CursorBenchCursorBench 4.0 This model — Terminal-Bench 4.0: 20.3 score (16.7th percentile) This model — DeepSWE 1.1: 65.2 score (31.2th percentile) This model — CursorBench 4.0: 40.4 score (12.5th percentile)

Each axis is this model's percentile among the 3 benchmarks it has published results for, measured against every other model with a score on that same benchmark. Percentiles are used because benchmarks do not share a scale — a 60 on one is not a 60 on another. Hover any point for the raw score.

Each strip shows every published score for that benchmark, with this model marked. The lighter shape behind the ticks is the density of results, and the dashed line is the median.

Cost against capability

Price and performance

Listed input price plotted against Terminal-Bench 4.0, the benchmark with the widest published coverage that this model appears in.

0 37 75 $0.1 $1 $10 Claude Fable 5.1 — $10/M, score 55.8 Claude Haiku 5.5 — $0.1/M, score 39.2 Claude Opus 5.5 — $4/M, score 66.4 Claude Sonnet 5.5 — $2/M, score 70.6 Grok 4.6 — $2/M, score 20.3 Grok 4.7 — $2/M, score 37.6 MiMo-V2.5-Pro — $0.435/M, score 1.5 MiMo-V2.6-Flash — $0.14/M, score 28.8 MiMo-V2.6-Pro — $0.435/M, score 34.9 Grok 4.6 Input price per million tokens (log scale) Score

The stepped line is the efficient frontier: at each price, the best score available for that money or less. A model sitting on it is not being beaten by anything cheaper. Price is log-scaled because listed rates span four orders of magnitude. Only models with both a listed price and a score on this benchmark can appear.
