Create a Mistral inference endpoint | Elasticsearch API documentation

Create a Mistral inference endpoint Added in 8.15.0

PUT /_inference/{task_type}/{mistral_inference_id}

Creates an inference endpoint to perform an inference task with the mistral service.

When you create an inference endpoint, the associated machine learning model is automatically deployed if it is not already running. After creating the endpoint, wait for the model deployment to complete before using it. To verify the deployment status, use the get trained model statistics API. Look for "state": "fully_allocated" in the response and ensure that the "allocation_count" matches the "target_allocation_count". Avoid creating multiple endpoints for the same model unless required, as each endpoint consumes significant resources.

Path parameters

task_type string Required

The task type. The only valid task type for the model to perform is text_embedding.

Value is text_embedding.
mistral_inference_id string Required

The unique identifier of the inference endpoint.

Body

chunking_settings object
Hide chunking_settings attributes Show chunking_settings attributes object
- max_chunk_size number
  
  The maximum size of a chunk in words. This value cannot be higher than 300 or lower than 20 (for sentence strategy) or 10 (for word strategy).
- overlap number
  
  The number of overlapping words for chunks. It is applicable only to a word chunking strategy. This value cannot be higher than half the max_chunk_size value.
- sentence_overlap number
  
  The number of overlapping sentences for chunks. It is applicable only for a sentence chunking strategy. It can be either 1 or 0.
- strategy string
  
  The chunking strategy: sentence or word.
service string Required

Value is mistral.
service_settings object Required
Hide service_settings attributes Show service_settings attributes object
- api_key string Required
  
  A valid API key of your Mistral account. You can find your Mistral API keys or you can create a new one on the API Keys page.
  
  IMPORTANT: You need to provide the API key only once, during the inference model creation. The get inference endpoint API does not retrieve your API key. After creating the inference model, you cannot change the associated API key. If you want to use a different API key, delete the inference model and recreate it with the same name and the updated API key.

- max_input_tokens number
  
  The maximum number of tokens per input before chunking occurs.
- model string Required
  
  The name of the model to use for the inference task. Refer to the Mistral models documentation for the list of available text embedding models.
