Models and providers
The registry is data, not logic. Prices are cached and carry the date they were read — 2026-06-24. A model that is not listed is still usable; it reports its cost as unknown rather than as a plausible guess.
Known models
| model | provider | input $/MTok | output $/MTok | context | tools |
|---|---|---|---|---|---|
claude-opus-5 |
anthropic | $5 | $25 | 1,000,000 | yes |
claude-sonnet-5 |
anthropic | $2 | $10 | 1,000,000 | yes |
claude-haiku-4-5 |
anthropic | $1 | $5 | 200,000 | yes |
The default when a key is present is claude-opus-5. Choosing a cheaper one is the operator's call, made in settings — not something this tool does quietly to save money.
Local models
Anything ollama list shows can be used, and costs nothing. These two were measured against this repository's own natural-language-to-filter cases and got every one right:

A local model not in that list is assumed to handle structured output and not to handle multi-turn tool use — the cautious assumption rather than the convenient one.
