## What it is
An open-source, community-contributed database of AI model specifications, pricing, and capabilities, stored as TOML files and served via JSON APIs and a searchable website. It provides provider-agnostic model metadata plus provider-specific serving details like context limits, modalities, and token pricing.

## Use cases
- look up AI model pricing and context limits
- find which models support tool calling or structured output
- get model metadata programmatically via API for my app
- compare LLM capabilities across providers
- fetch provider logos for a model catalog UI
- keep model specs in my AI SDK app up to date

## When to choose
- you need a single up-to-date source of AI model specs and pricing
- you're building tooling that needs model metadata like context windows or token costs
- you want community-maintained, MIT-licensed model data with a simple JSON API

## When to avoid
- you need real-time benchmark results or live availability of models
- you need data guaranteed accurate without community review delays
- you need a database of non-AI models or fine-tuned private models
