Overview

Model selection / route and cost brief / which model / prompt cost in one call: describe a task and get a recommended model tier, candidate models, and, when you pass a sample prompt, its token count, a projected cost across those candidates, and a compressed version of the prompt. Composite: one call runs model-route-recommend + llm-cost-estimate + token-count + prompt-compress, merged into {route, token_count, cost_estimate, compressed_prompt}. model-route-recommend picks a tier and named models from the task and optional latency/budget/context constraints; token-count and llm-cost-estimate price that exact prompt against the recommended models; prompt-compress shortens the same prompt. Without a sample prompt, only routing runs. Use it as a model selection API, an LLM routing advisor, or a which-model-should-I-call tool.
