}What it tracks
A comprehensive registry covering every dimension of the AI model ecosystem.
Providers
Anthropic, OpenAI, Google, Meta, Mistral, Cohere, xAI, and more. Every major AI provider indexed.
Model Families
Groups of related models — Claude Sonnet, GPT-4o, Llama 3, Gemini Pro — with full evolution history.
Versions
Individual releases with release dates, deprecation dates, and sunset dates. Full lifecycle metadata.
Aliases
Every known string identifier across SDKs — official, Bedrock, Vertex, LiteLLM, LangChain, Azure, and more.
Lifecycle
Active, latest, deprecated, sunset. Track every status transition with precise dates and upgrade paths.
Parameters & Context
Parameter counts, context windows, input/output token limits. Compare capabilities across models.
How it works
Three stages, fully automated. Fresh data every day, no effort on your part.
We ingest
Automated pipelines poll provider APIs, scrape deprecation feeds, and sync Hugging Face daily.
We normalize
Raw data is cleaned, deduplicated, and mapped to a canonical schema with aliases for every platform.
You query
Simple REST API returns structured JSON — models, aliases, upgrades, lifecycle status, and more.
API preview
Real endpoints, real responses. The resolve endpoint is the heart of Model Graph — give it any model string, get back the canonical model and its upgrade.
