TTFT: Time to First Token (latency before model starts generating)

TTFAT: Time to First Answer Token (latency before model starts answering, after reasoning)

Intelligence Index: Relative capability score based on benchmark performance (higher is better)

Thinking/Reasoning: Models that show their reasoning process before answering (values in parentheses show performance when reasoning is enabled)

All pricing is per million tokens. Performance metrics are approximate and may vary based on query complexity and API load.
