Pricing and performance
Per provider and reported configuration. Prices are USD per 1M tokens.
No provider pricing or performance reports have been added for this model yet.
Blended token cost
USD per 1M tokens · 50% input + 50% output · lower is better
No sourced current price for Claude Mythos 5.1.10 of 45 priced models selected
Pricing details and sources
Blended cost = (input price + output price) ÷ 2: 500,000 input and 500,000 output tokens. Each model uses its lowest sourced current provider rate, excluding batch and Flex tiers. Cache discounts, tool fees and workload-specific token usage are excluded. 52 models without complete sourced current prices are unavailable in this comparison. The default selection is this model and the nine closest in blended cost; if this model has no price, we show the ten cheapest. The scale stays fixed across pages of your selection.

Output speed
Output tokens per second · higher is better
No sourced output speed for Claude Mythos 5.1.10 of 33 models with reports selected
Measurement details and sources
Output speed measures generated tokens per second. Each model uses its fastest sourced current provider report. Batch and Flex tiers are excluded. Provider, configuration, prompt and reporting methods can differ, so these are reported observations rather than controlled head-to-head tests. 64 models have no qualifying sourced speed report. Defaults include this model and the nine closest reported values, or the ten leading models if this model has no report. The scale stays fixed across selected pages.

Latency
Time to first token in seconds · lower is better
No sourced time-to-first-token latency for Claude Mythos 5.1.10 of 32 models with reports selected
Measurement details and sources
Latency measures time to first token (TTFT), converted to seconds. Each model uses its lowest sourced current TTFT report; total response time is excluded. Batch and Flex tiers are excluded. Provider, configuration, prompt and reporting methods can differ, so these are reported observations rather than controlled head-to-head tests. 65 models have no qualifying sourced latency report. Defaults include this model and the nine closest reported values, or the ten leading models if this model has no report. The scale stays fixed across selected pages.
