LLM Prices — daily-verified LLM API pricing data

Machine-readable LLM API pricing for 156 current models across 28 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.

The LLM Price Index

A fixed, equal-weighted basket of frontier flagship models, blended 3:1 input:output, re-verified daily — a single citeable number for "what does a million tokens of frontier intelligence cost?" Methodology: https://modelpricewatch.com/price-index/methodology/

Caveats (honesty first)

• History points are labelled by source: our own verified/snapshot captures vs litellm-archive (reconstructed from the open-source LiteLLM repo's git history — marked, never mixed silently).
• A deeper 2024→2026 history backfill is in progress; some models currently have short timelines. Known baseline discontinuities are under audit.
