Create a Watsonx inference endpoint Generally available; Added in 8.16.0

PUT /_inference/{task_type}/{watsonx_inference_id}

Create an inference endpoint to perform an inference task with the watsonxai service. You need an IBM Cloud Databases for Elasticsearch deployment to use the watsonxai inference service. You can provision one through the IBM catalog, the Cloud Databases CLI plug-in, the Cloud Databases API, or Terraform.

Required authorization

Cluster privileges: manage_inference

Path parameters

task_type string

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

Value is text_embedding.
watsonx_inference_id string Required

The unique identifier of the inference endpoint.

Query parameters

timeout string

Specifies the amount of time to wait for the inference endpoint to be created.

External documentation

application/json

Body Required

service string Required

The type of service supported for the specified task type. In this case, watsonxai.

Value is watsonxai.
service_settings object Required

Settings used to install the inference model. These settings are specific to the watsonxai service.
Hide service_settings attributes Show service_settings attributes object
- api_key string Required
  
  A valid API key of your Watsonx account. You can find your Watsonx 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.
  
  External documentation
- api_version string Required
  
  A version parameter that takes a version date in the format of YYYY-MM-DD. For the active version data parameters, refer to the Wastonx documentation.
  
  External documentation
- model_id string Required
  
  The name of the model to use for the inference task. Refer to the IBM Embedding Models section in the Watsonx documentation for the list of available text embedding models.
  
  External documentation
- project_id string Required
  
  The identifier of the IBM Cloud project to use for the inference task.
- rate_limit object
  
  This setting helps to minimize the number of rate limit errors returned from Watsonx. By default, the watsonxai service sets the number of requests allowed per minute to 120.
  Hide rate_limit attribute Show rate_limit attribute object
  
  requests_per_minute number
  
  The number of requests allowed per minute.
- url string Required
  
  The URL of the inference endpoint that you created on Watsonx.

  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).
  
  Default value is 250.
  
  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.
  
  Default value is 100.
  
  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.
  
  Default value is 1.
  
  strategy string
  
  The chunking strategy: sentence or word.
  
  Default value is sentence.
- service string Required
  
  The service type
- service_settings object Required

  Task settings specific to the service and task type
- inference_id string Required
  
  The inference Id
- task_type string Required
  
  The task type
  
  Value is text_embedding.
