NVIDIA NIM

NVIDIA NIM Models API

OpenAI-compatible model catalog endpoint (/v1/models) returning the list of models served by the NIM endpoint or container. Each entry includes id, owned_by, and created timestamp. Used by clients to discover the model name strings to pass to chat-completions / completions / embeddings.

Operations 2

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /v1/models List the models this NIM endpoint serves · List Available Models #
Ask an LLM
“Which models are available on this NIM endpoint or container?”
“Can I see every model id I'm able to call before sending inference requests?”
Tell an agent
List all models exposed by this NIM endpoint.
Show me the full catalog of model ids I can call here.
GET /v1/models/{model_id} Get details for one model · Retrieve A Model #
Ask an LLM
“What metadata is available for one specific model id on the NIM endpoint?”
“Can I look up a single model to confirm it exists before calling it?”
Tell an agent
Get the metadata for model {model_id}.
Look up model {model_id} and show its details.
