Model IDs contain a slash (`primalabs-ai/DeepSeek-V4.1-Flash-1017`), so the path is the ID as is: `/models/primalabs-ai/DeepSeek-V4.1-Flash-1017`. ## OpenAPI ````yaml /api-reference/inference/openapi.yaml get /models/{owner}/{model} openapi: 3.1.0 info: title: PrimaLabs Inference API version: 1.0.0 description: > Serverless LLM inference on PrimaLabs. The API is OpenAI-compatible: point any OpenAI SDK at the base URL below and pass a PrimaLabs API key as the bearer token. Anthropic (`/messages`) and OpenAI Responses (`/responses`) formats are also accepted as passthroughs. This is a **curated** spec covering the endpoints we serve; it is maintained by hand.
