Rhumb and models.dev
models.dev is an open (MIT) list of models: capabilities, limits and list prices, free to download with no key. Rhumb reads it every day, with the providers' own lists and other sources (see Attributions), and does the part a list leaves to you: choosing.
| Aspect | models.dev | Rhumb |
|---|---|---|
| What you get | Every model, as data. | One answer, with its reason and the next alternatives. |
| Your providers and terms | You filter and apply your own discounts yourself. | providers and provider_terms: the cheapest offering of the chosen model on your accounts. |
| Capabilities | Flags as each source states them. | Each one graded by its evidence: claimed, parsed, native or probed on our own keys. |
| Quality | Benchmark results are starting to appear, mostly as the labs report them. | Scores from LMArena, Epoch AI and MTEB, normalised per benchmark and banded, each with its source's notice. |
| Retirements | A status field. | Deprecations, retirements and redirects followed daily, so an answer moves before a model stops answering. |
| Local models | Cloud providers. | Ollama, LM Studio, llama.cpp, MLX and WebLLM too, sized to your device. |
| What it costs | Free. | A free plan and free test keys; paid plans by calls a month. |
When models.dev is the better fit
- You want the raw data with no key, to build your own selection.
- You need a model or provider Rhumb doesn't list: models.dev lists more, including makers Rhumb hasn't reviewed.
