Tools & capabilities
Onomeo tools 3
list_modelsLists the models served right now, split into free and pay-as-you-go, with the current free call limit. Needs no API key.ask_modelSends a prompt to one model and returns the answer. `model` defaults to `auto`, which picks a healthy free model and reports which one answered.compare_modelsSends the same prompt to 2-4 models in parallel and returns the answers side by side.
Tokencost Dev tools 4
get_model_detailsLook up pricing, context window, and capabilities for an LLM model. Uses fuzzy matching so you don't need the exact model key.calculate_estimateEstimate the cost for a given number of input and output tokens on a specific model. Supports optional cached_tokens for prompt caching discounts.compare_modelsFilter and compare models by provider, minimum context window, or mode. Returns top 5 most cost-effective matches.refresh_pricesForce a re-fetch of pricing data from the LiteLLM registry. Use this if you suspect the cached data is stale.
