2 providers list the identical $0.018 input rate, so price alone will not separate them — compare context limits, max output, and capabilities above.
Context limits also differ by provider, from 32.768K to 131.072K tokens. Compare the provider table above before choosing on price alone.

Each axis is this model's percentile among the 5 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.

GPT OSS 20B
Input price per million tokens (log scale)
Index
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.
