AlibabaCloud AI Search inference integration

Elastic Stack Serverless

Creates an inference endpoint to perform an inference task with the alibabacloud-ai-search service.

PUT /_inference/<task_type>/<inference_id>

<inference_id>

(Required, string) The unique identifier of the inference endpoint.

<task_type>

(Required, string) The type of the inference task that the model will perform.

Available task types:

• completion,
• rerank
• sparse_embedding,
• text_embedding.

chunking_settings

(Optional, object) Chunking configuration object. Refer to Configuring chunking to learn more about chunking.

max_chunk_size

(Optional, integer) Specifies the maximum size of a chunk in words. Defaults to 250. This value cannot be higher than 300 or lower than 20 (for sentence strategy) or 10 (for word strategy).

overlap

(Optional, integer) Only for word chunking strategy. Specifies the number of overlapping words for chunks. Defaults to 100. This value cannot be higher than the half of max_chunk_size.

sentence_overlap

(Optional, integer) Only for sentence chunking strategy. Specifies the numnber of overlapping sentences for chunks. It can be either 1 or 0. Defaults to 1.

strategy

(Optional, string) Specifies the chunking strategy. It could be either sentence or word.

service

(Required, string) The type of service supported for the specified task type. In this case, alibabacloud-ai-search.

service_settings

(Required, object) Settings used to install the inference model.

These settings are specific to the alibabacloud-ai-search service.

api_key

(Required, string) A valid API key for the AlibabaCloud AI Search API.

service_id

(Required, string) The name of the model service to use for the inference task.

Available service_ids for the completion task:

* ops-qwen-turbo
* qwen-turbo
* qwen-plus
* qwen-max ÷ qwen-max-longcontext

For the supported completion service_ids, refer to the documentation.

Available service_id for the rerank task is:

* ops-bge-reranker-larger

For the supported rerank service_id, refer to the documentation.

Available service_id for the sparse_embedding task:

* ops-text-sparse-embedding-001

For the supported sparse_embedding service_id, refer to the documentation.

Available service_ids for the text_embedding task:

* ops-text-embedding-001
* ops-text-embedding-zh-001
* ops-text-embedding-en-001
* ops-text-embedding-002

For the supported text_embedding service_ids, refer to the documentation.

host

(Required, string) The name of the host address used for the inference task. You can find the host address at the API keys section of the documentation.

workspace

(Required, string) The name of the workspace used for the inference task.

rate_limit

(Optional, object) By default, the alibabacloud-ai-search service sets the number of requests allowed per minute to 1000. This helps to minimize the number of rate limit errors returned from AlibabaCloud AI Search. To modify this, set the requests_per_minute setting of this object in your service settings:

text "rate_limit": { "requests_per_minute": <<number_of_requests>> }

task_settings

(Optional, object) Settings to configure the inference task. These settings are specific to the <task_type> you specified.

`task_settings` for the `text_embedding` task type

input_type

(Optional, string) Specifies the type of input passed to the model. Valid values are:

* ingest: for storing document embeddings in a vector database.
* search: for storing embeddings of search queries run against a vector database to find relevant documents.

`task_settings` for the `sparse_embedding` task type

input_type

(Optional, string) Specifies the type of input passed to the model. Valid values are:

* ingest: for storing document embeddings in a vector database.
* search: for storing embeddings of search queries run against a vector database to find relevant documents.

return_token

(Optional, boolean) If true, the token name will be returned in the response. Defaults to false which means only the token ID will be returned in the response.

The following example shows how to create an inference endpoint called alibabacloud_ai_search_completion to perform a completion task type.

 PUT _inference/completion/alibabacloud_ai_search_completion {
    "service": "alibabacloud-ai-search",
    "service_settings": {
        "host" : "default-j01.platform-cn-shanghai.opensearch.aliyuncs.com",
        "api_key": "{{API_KEY}}",
        "service_id": "ops-qwen-turbo",
        "workspace" : "default"
    }
}

The next example shows how to create an inference endpoint called alibabacloud_ai_search_rerank to perform a rerank task type.

 PUT _inference/rerank/alibabacloud_ai_search_rerank {
    "service": "alibabacloud-ai-search",
    "service_settings": {
        "api_key": "<api_key>",
        "service_id": "ops-bge-reranker-larger",
        "host": "default-j01.platform-cn-shanghai.opensearch.aliyuncs.com",
        "workspace": "default"
    }
}

The following example shows how to create an inference endpoint called alibabacloud_ai_search_sparse to perform a sparse_embedding task type.

 PUT _inference/sparse_embedding/alibabacloud_ai_search_sparse {
