cerebras

cerebras_chat_completion

Send a conversation to a Cerebras model and return its reply (the full API response: choices, message content, usage). Streaming is off. Output is model-generated text, not human-written. Each call uses tokens from your Cerebras limits. Cerebras API: POST /v1/chat/completions.

cerebras_get_model

Get one model by id: its id, object type, creation time and owner. Cerebras API: GET /v1/models/{model_id}.

cerebras_list_models

List the models available to your Cerebras account (for example gpt-oss-120b, qwen-3.8-27b). Call this first, because model ids change. Cerebras API: GET /v1/models.
