Cheapest model Models tracked Glama MCP server

Machine-readable LLM API pricing for 173 current models across 26 providers (OpenAI, Anthropic, Google, Mistral, xAI, DeepSeek, Meta, Groq, Together, …), maintained by modelpricewatch.com.

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.
