AuthThe Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats.AvailabilityGenerally available since 8.12This functionality is generally available and ready for production usage.Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments.This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.
Create an inference endpoint to perform an inference task with the amazonbedrock service.
Note
You need to provide the access and secret keys only once, during the inference model creation. The get inference API does not retrieve your access or secret keys. After creating the inference model, you cannot change the associated key pairs. If you want to use a different access and secret key pair, delete the inference model and recreate it with the same name and the updated keys.
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).
overlapnumber · default: 100
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_overlapnumber · default: 1
The number of overlapping sentences for chunks.
It is applicable only for a sentence chunking strategy.
It can be either 1 or 0.
strategystring · default: sentence
The chunking strategy: sentence or word.
serviceenumrequired
The type of service supported for the specified task type. In this case, amazonbedrock.
Values:amazonbedrock
service_settingsobjectrequired
Settings used to install the inference model. These settings are specific to the amazonbedrock service.
access_keystringrequired
A valid AWS access key that has permissions to use Amazon Bedrock and access to models for inference requests.
modelstringrequired
The base model ID or an ARN to a custom model based on a foundational model.
The base model IDs can be found in the Amazon Bedrock documentation.
Note that the model ID must be available for the provider chosen and your IAM user must have access to the model.
This setting helps to minimize the number of rate limit errors returned from Amazon Bedrock.
By default, the amazonbedrock service sets the number of requests allowed per minute to 240.
requests_per_minutenumber
The number of requests allowed per minute.
secret_keystringrequired
A valid AWS secret key that is paired with the access_key.
For informationg about creating and managing access and secret keys, refer to the AWS documentation.
Settings to configure the inference task.
These settings are specific to the task type you specified.
max_new_tokensnumber · default: 64
For a completion task, it sets the maximum number for the output tokens to be generated.
temperaturenumber
For a completion task, it is a number between 0.0 and 1.0 that controls the apparent creativity of the results.
At temperature 0.0 the model is most deterministic, at temperature 1.0 most random.
It should not be used if top_p or top_k is specified.
top_knumber
For a completion task, it limits samples to the top-K most likely words, balancing coherence and variability.
It is only available for anthropic, cohere, and mistral providers.
It is an alternative to temperature; it should not be used if temperature is specified.
top_pnumber
For a completion task, it is a number in the range of 0.0 to 1.0, to eliminate low-probability tokens.
Top-p uses nucleus sampling to select top tokens whose sum of likelihoods does not exceed a certain value, ensuring both variety and coherence.
It is an alternative to temperature; it should not be used if temperature is specified.
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).
overlapnumber · default: 100
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_overlapnumber · default: 1
The number of overlapping sentences for chunks.
It is applicable only for a sentence chunking strategy.
It can be either 1 or 0.
strategystring · default: sentence
The chunking strategy: sentence or word.
