OpenAI inference service
editOpenAI inference service
editCreates an inference endpoint to perform an inference task with the openai
service.
Request
editPUT /_inference/<task_type>/<inference_id>
Path parameters
edit-
<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
, -
text_embedding
.
-
Request body
edit-
chunking_settings
-
(Optional, object) Chunking configuration object. Refer to Configuring chunking to learn more about chunking.
-
max_chunking_size
-
(Optional, integer)
Specifies the maximum size of a chunk in words.
Defaults to
250
. This value cannot be higher than300
or lower than20
(forsentence
strategy) or10
(forword
strategy). -
overlap
-
(Optional, integer)
Only for
word
chunking strategy. Specifies the number of overlapping words for chunks. Defaults to100
. This value cannot be higher than the half ofmax_chunking_size
. -
sentence_overlap
-
(Optional, integer)
Only for
sentence
chunking strategy. Specifies the numnber of overlapping sentences for chunks. It can be either1
or0
. Defaults to1
. -
strategy
-
(Optional, string)
Specifies the chunking strategy.
It could be either
sentence
orword
.
-
-
service
-
(Required, string)
The type of service supported for the specified task type. In this case,
openai
. -
service_settings
-
(Required, object) Settings used to install the inference model.
These settings are specific to the
openai
service.-
api_key
-
(Required, string) A valid API key of your OpenAI account. You can find your OpenAI API keys in your OpenAI account under the API keys section.
You need to provide the API key only once, during the inference model creation. The Get inference 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
-
(Optional, integer)
The number of dimensions the resulting output embeddings should have.
Only supported in
text-embedding-3
and later models. If not set the OpenAI defined default for the model is used. -
model_id
- (Required, string) 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
- (Optional, string) The unique identifier of your organization. You can find the Organization ID in your OpenAI account under Settings > Organizations.
-
url
-
(Optional, string)
The URL endpoint to use for the requests.
Can be changed for testing purposes.
Defaults to
https://api.openai.com/v1/embeddings
. -
rate_limit
-
(Optional, object) The
openai
service sets a default number of requests allowed per minute depending on the task type. Fortext_embedding
it is set to3000
. Forcompletion
it is set to500
. This helps to minimize the number of rate limit errors returned from OpenAI. To modify this, set therequests_per_minute
setting of this object in your service settings:"rate_limit": { "requests_per_minute": <<number_of_requests>> }
More information about the rate limits for OpenAI can be found in your Account limits.

-
task_settings
-
(Optional, object) Settings to configure the inference task. These settings are specific to the
<task_type>
you specified.task_settings
for thecompletion
task type-
user
- (Optional, string) Specifies the user issuing the request, which can be used for abuse detection.
task_settings
for thetext_embedding
task type-
user
- (optional, string) Specifies the user issuing the request, which can be used for abuse detection.

OpenAI service example
editThe following example shows how to create an inference endpoint called openai-embeddings
to perform a text_embedding
task type.
The embeddings created by requests to this endpoint will have 128 dimensions.
const response = await client.inference.put({ task_type: "text_embedding", inference_id: "openai-embeddings", inference_config: { service: "openai", service_settings: { api_key: "<api_key>", model_id: "text-embedding-3-small", dimensions: 128, }, }, }); console.log(response);
PUT _inference/text_embedding/openai-embeddings { "service": "openai", "service_settings": { "api_key": "<api_key>", "model_id": "text-embedding-3-small", "dimensions": 128 } }
The next example shows how to create an inference endpoint called openai-completion
to perform a completion
task type.
resp = client.inference.put( task_type="completion", inference_id="openai-completion", inference_config={ "service": "openai", "service_settings": { "api_key": "<api_key>", "model_id": "gpt-3.5-turbo" } }, ) print(resp)
const response = await client.inference.put({ task_type: "completion", inference_id: "openai-completion", inference_config: { service: "openai", service_settings: { api_key: "<api_key>", model_id: "gpt-3.5-turbo", }, }, }); console.log(response);
PUT _inference/completion/openai-completion { "service": "openai", "service_settings": { "api_key": "<api_key>", "model_id": "gpt-3.5-turbo" } }
