How to read this comparison

01Prices are standard paid-tier list prices in USD per 1 million tokens. Taxes, batch discounts, caching, tool calls, and provider-specific charges are not included.
02Gemini output pricing includes thinking tokens, so reasoning can affect the final output-token charge.
03OpenAI charges higher long-context rates above 272K input tokens. Gemini 3.1 Pro uses higher rates for prompts above 200K tokens.
04Intelligence and speed are editorial relative guides derived from each provider’s product positioning. Real latency changes with prompt length, reasoning, region, and service load.
