About
aimodelscomparison.com is an independent catalog and comparison engine for 1,213 of the most-used open-weights models on Hugging Face and 210 API-only models (GPT, Claude, Gemini, Grok and others you can only call through a hosted API). We answer the questions model cards and price lists don't: which models are actually gaining ground (from our own daily download snapshots), can your hardware run one (estimated VRAM per quantization), is it cheaper to self-host or to call an API (prices per 1M tokens next to the hardware you'd need), and how two models really differ (spec diffs, licence classes, benchmarks, the same prompts run on both).
Data comes from the public Hugging Face Hub API and the public OpenRouter API, refreshed nightly; benchmark indices are Artificial Analysis and Design Arena figures as published by OpenRouter. Every day we record a download snapshot for each open-weights model and a price snapshot for each model served via API — history neither source exposes. Everything derived is documented on the methodology page and available raw through the JSON API and llms.txt.
AI agents can query the catalog directly through our free MCP server, so coding assistants like Claude, Cursor or ChatGPT can look up current model IDs, deprecations, VRAM needs and prices instead of relying on their training data.
