Model Compatibility
Domain: Models & Providers
Motivation
Model compatibility is which capabilities a model supports — tools, reasoning, streaming, images, and system-prompt update mode. The exact-model metadata exposes reasoningEfforts, input modalities, and systemPromptUpdate; the LLM service resolves these via ctx.llm.resolveModelInfo() and validates a request’s call config against the exact model before any provider I/O.
Concrete Example
deepseek-flash is text- and image-capable with in-history system updates, while deepseek-v4-pro is text-only; a request is checked against the exact model before dispatch.
Analogy
The spec sheet listing which features a given car model actually has.
