Overview

Create a custom inference endpoint.

The custom service gives more control over how to interact with externalinference services that aren't explicitly supported through dedicatedintegrations.The custom service gives you the ability to define the headers, url, queryparameters, request body, and secrets.The custom service supports the template replacement functionality, whichenables you to define a template that can be replaced with the valueassociated with that key.Templates are portions of a string that start with `${` and end with `}`.The parameters `secret_parameters` and `task_settings` are checked for keysfor template replacement. Template replacement is supported in the `request`,`headers`, `url`, and `query_parameters`.If the definition (key) is not found for a template, an error message isreturned.In case of an endpoint definition like the following:```PUT _inference/text_embedding/test-text-embedding

{  "service": "custom",  "service_settings": {     "secret_parameters": {          "api_key": "<some api key>"     },     "url": "...endpoints.huggingface.cloud/v1/embeddings",     "headers": {         "Authorization": "Bearer ${api_key}",         "Content-Type": "application/json"     },     "request": "{\"input\": ${input}}",     "response": {         "json_parser": {             "text_embeddings":"$.data[*].embedding[*]"         }     }  }}

```To replace `${api_key}` the `secret_parameters` and `task_settings` arechecked for a key named `api_key`.

> info> Templates should not be surrounded by quotes.

Pre-defined templates:* `${input}` refers to the array of input strings that comes from the `input`field of the subsequent inference requests.* `${input_type}` refers to the input type translation values.* `${query}` refers to the query field used specifically for reranking tasks.* `${top_n}` refers to the `top_n` field available when performing rerankrequests.* `${return_documents}` refers to the `return_documents` field available whenperforming rerank requests.

Types

typeNewPutCustom

type NewPutCustom func(tasktype, custominferenceidstring) *PutCustom

NewPutCustom type alias for index.

funcNewPutCustomFunc

func NewPutCustomFunc(tpelastictransport.Interface)NewPutCustom

NewPutCustomFunc returns a new instance of PutCustom with the provided transport.Used in the index of the library this allows to retrieve every apis in once place.

typePutCustom

type PutCustom struct {// contains filtered or unexported fields}

func (*PutCustom)ChunkingSettings

func (r *PutCustom) ChunkingSettings(chunkingsettings *types.InferenceChunkingSettings) *PutCustom

ChunkingSettings The chunking configuration object.API name: chunking_settings

func (PutCustom)Do

func (rPutCustom) Do(providedCtxcontext.Context) (*Response,error)

Do runs the request through the transport, handle the response and returns a putcustom.Response

func (*PutCustom)ErrorTrace

func (r *PutCustom) ErrorTrace(errortracebool) *PutCustom

ErrorTrace When set to `true` Elasticsearch will include the full stack trace of errorswhen they occur.API name: error_trace

func (*PutCustom)FilterPath

func (r *PutCustom) FilterPath(filterpaths ...string) *PutCustom

FilterPath Comma-separated list of filters in dot notation which reduce the responsereturned by Elasticsearch.API name: filter_path
