Seamless Integration with Amazon Bedrock API for AI-Powered Text and Image Generation in Ruby 🤖 + 💎. Amazon Bedrock API.
Amazon Bedrock is a fully managed service that makes FMs from leading AI startups and Amazon available via an API, so you can choose from a wide range of FMs to find the model that is best suited for your use case.
Add the following line to your application's Gemfile:
gem "ruby-amazon-bedrock", "~> 0.2.3"And then execute:
$ bundle installOr install with:
$ gem install ruby-amazon-bedrock -v 0.2.3and require with:
require "amazon_bedrock"In order to use Amazon Bedrock, you'll need your secure credentials just as any other AWS service. Get your keys from AWS IAM (Identity and Access Management) https://us-east-1.console.aws.amazon.com/iam
To use Bedrock, you must request access to Bedrock's FMs. To do so, you will need to have the correct IAM Permissions. For certain models, you may first need to submit use case details before you are able to request access.
Be aware that by using ruby-amazon-bedrock gem in conjunction with Amazon Bedrock, you may incur costs associated with the use of Amazon Bedrock services. As the user, you are solely responsible for any and all costs that arise from your use of Amazon Bedrock. You can see more details about pricing here
Instantiate a client by passing your AWS IAM credentials:
client = RubyAmazonBedrock::Client.new(
region: "AWS_REGION",
access_key_id: "AWS_ACCESS_KEY_ID",
access_token: "AWS_SECRET_ACCESS_KEY"
)RubyAmazonBedrock.configure do |config|
config.region = ENV.fetch('AWS_REGION', nil)
config.access_key_id = ENV.fetch('AWS_ACCESS_KEY_ID', nil)
config.secret_access_key = ENV.fetch('AWS_SECRET_ACCESS_KEY', nil)
end
client = RubyAmazonBedrock::Client.newThe options argument enhances the method's flexibility by allowing additional, model-specific configurations. If not explicitly provided, the method defaults to a set of standard Model parameters. You can see more details about a Model's optional parameters.
