How to read this comparison
- 01Every price is the standard paid-tier list price, in USD per 1M tokens. Tax, batch discounts, caching, and tool fees are not included.
- 02Gemini output prices count thinking tokens. Heavier reasoning therefore costs more even when the visible answer is the same length.
- 03Long prompts are billed at a higher rate: OpenAI above 272K input tokens, Gemini 3.1 Pro and Grok 4.6 / 4.5 / 4.3 from 200K. DeepSeek is listed at its cache-miss rate, and cache hits cost less.
- 04Intelligence is a 1–5 band over the median of three platforms: the Artificial Analysis Intelligence Index, LMArena Elo, and the llm-stats Reasoning Index. Speed bands Artificial Analysis and OpenRouter output tokens per second rather than first-token latency, which is why the strongest reasoning models land low.
- 05DeepSeek bills by time of day from 2026-08-16. Peak is 01:00–04:00 and 06:00–10:00 UTC, and off-peak costs half the peak rate.
- 06Gemini 3.6 and 3.7 Flash are on an introductory rate until 2026-12-31. From 2027-01-01 they bill at $1.50 input and $7.50 output.
