Machine-readable LLM API pricing for 177 current models across 27 providers (OpenAI, Anthropic, Google, Mistral, xAI, DeepSeek, Meta, Groq, Together, …), maintained by modelpricewatch.com. Every price links to the provider's official pricing page; prices are cross-checked daily against an independent reference and top models are re-read weekly from the provider pages with dated receipts.
