Create an OpenAI inference endpoint Added in 8.12.0

PUT /_inference/{task_type}/{openai_inference_id}
Api key auth Basic auth Bearer auth

Create an inference endpoint to perform an inference task with the openai service or openai compatible APIs.

Path parameters

  • task_type string Required

    The type of the inference task that the model will perform. NOTE: The chat_completion task type only supports streaming and only through the _stream API.

    Values are chat_completion, completion, or text_embedding.

  • openai_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 openai.

  • service_settings object Required
    Hide service_settings attributes Show service_settings attributes object
    • api_key string Required

      A valid API key of your OpenAI account. You can find your OpenAI API keys in your OpenAI account under the API keys section.

      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.

    • dimensions number

      The number of dimensions the resulting output embeddings should have. It is supported only in text-embedding-3 and later models. If it is not set, the OpenAI defined default for the model is used.

    • model_id string Required

      The name of the model to use for the inference task. Refer to the OpenAI documentation for the list of available text embedding models.

    • organization_id string

      The unique identifier for your organization. You can find the Organization ID in your OpenAI account under Settings > Organizations.

    • rate_limit object
      Hide rate_limit attribute Show rate_limit attribute object
    • url string

      The URL endpoint to use for the requests. It can be changed for testing purposes.

  • task_settings object
    Hide task_settings attribute Show task_settings attribute object
    • user string

      For a completion or text_embedding task, specify the user issuing the request. This information can be used for abuse detection.
