Body Required

• chunking_settings object

  The chunking configuration object. Applies only to the text_embedding task type. Not applicable to the rerank, completion or chat_completion task types.

  • max_chunk_size number

    The maximum size of a chunk in words. This value cannot be lower than 20 (for sentence strategy) or 10 (for word strategy). This value should not exceed the window size for the associated model.

    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.

  • separator_group string

    Only applicable to the recursive strategy and required when using it.

    Sets a predefined list of separators in the saved chunking settings based on the selected text type. Values can be markdown or plaintext.

    Using this parameter is an alternative to manually specifying a custom separators list.

  • separators array[string]

    Only applicable to the recursive strategy and required when using it.

    A list of strings used as possible split points when chunking text.

    Each string can be a plain string or a regular expression (regex) pattern. The system tries each separator in order to split the text, starting from the first item in the list.

    After splitting, it attempts to recombine smaller pieces into larger chunks that stay within the max_chunk_size limit, to reduce the total number of chunks generated.

  • strategy string

    The chunking strategy: sentence, word, none or recursive.

    • If strategy is set to recursive, you must also specify:

      • max_chunk_size
      • either separators orseparator_group

    Learn more about different chunking strategies in the linked documentation.

    Default value is sentence.

    External documentation
• 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.

  • 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.

    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. Refer to the IBM library - Foundation models in Watsonx.ai.

    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.

    • requests_per_minute number

      The number of requests allowed per minute. By default, the number of requests allowed per minute is set by each service as follows:

      • alibabacloud-ai-search service: 1000
      • amazonbedrock service: 240
      • anthropic service: 50
