How to read this table honestly
- Cached input is not one thing. Anthropic and DeepSeek list a cache-read price; Anthropic also bills cache writes (1.25x input), Google bills cache storage per hour. Two providers with the same "cached" number can produce different bills.
- "Tiered" means the listed price is the floor. OpenAI's GPT-5.5/5.4 and Google's Pro models charge roughly double for long-context requests, which is exactly what agent workflows produce.
- Batch discounts are large. Anthropic, OpenAI, and Mistral all offer 50 percent off for async batch workloads; xAI 20 to 50 percent.
- Excluded providers are excluded for a reason. Meta Llama API, Cohere, and Amazon Nova render their prices client-side, so they could not be verified from source. No number on this page is quoted from a third-party blog.
