Integrating Open-WebUI with Amazon Bedrock

In this tutorial, we'll explore one of the most common and popular approaches to integrate Open-WebUI with Amazon Bedrock.

Prerequisites​

In order to follow this tutorial, you must have the following:

  • An active AWS account
  • An active AWS Access Key and Secret Key
  • IAM permissions in AWS to enable Bedrock models or already enabled models
  • Docker installed on your system

What is Amazon Bedrock​

Direct from AWS' website:

"Amazon Bedrock is a fully managed service that offers a choice of high-performing foundation models (FMs) from leading AI companies like AI21 Labs, Anthropic, Cohere, Luma, Meta, Mistral AI, poolside (coming soon), Stability AI, and Amazon through a single API, along with a broad set of capabilities you need to build generative AI applications with security, privacy, and responsible AI. Using Amazon Bedrock, you can easily experiment with and evaluate top FMs for your use case, privately customize them with your data using techniques such as fine-tuning and Retrieval Augmented Generation (RAG), and build agents that execute tasks using your enterprise systems and data sources. Since Amazon Bedrock is serverless, you don't have to manage any infrastructure, and you can securely integrate and deploy generative AI capabilities into your applications using the AWS services you are already familiar with."

Integration Steps

Step 1: Verify access to Amazon Bedrock Base Models​

Before we can integrate with Bedrock, you first have to verify that you have access to at least one, but preferably many, of the available Base Models. At the time of this writing (Feb 2025), there were 47 base models available. You can see in the screenshot below that I have access to multiple models. You'll know if you have access to a model if it says "✅ Access Granted" next to the model. If you don't have access to any models, you will get an error on the next step.

AWS provides good documentation for request accessing / enabling these models here: Amazon Bedrock's Model Access Docs

Step 2: Configure the Bedrock Access Gateway​

Now that we have access to at least one Bedrock base model, we need to configure the Bedrock Access Gateway, or BAG. You can think of the BAG as kind of proxy or middleware developed by AWS that wraps around AWS native endpoints/SDK for Bedrock and, in turn, exposes endpoints that are compatible with OpenAI's schema, which is what Open-WebUI requires.

For reference, here is a simple mapping between the endpoints:

OpenAI EndpointBedrock Method
/modelslist_inference_profiles
/models/{model_id}list_inference_profiles
/chat/completionsconverse or converse_stream
/embeddingsinvoke_model

The BAG repo can be found here: Bedrock Access Gateway Repo

To set-up the BAG, follow the below steps:

  • Clone the BAG repo
  • Remove the default dockerfile
  • Change the name of the Dockerfile_ecs to Dockerfile

We're now ready to build and launch the docker container using:

docker build . -f Dockerfile -t bedrock-gateway

docker run -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY="$AWS_SECRET_ACCESS_KEY" -e AWS_REGION=us-east-1 -d -p 8000:80 bedrock-gateway

You should now be able to access the BAG's swagger page at: http://localhost:8000/docs

Step 3: Add Connection in Open-WebUI​

Now that you the BAG up-and-running, it's time to add it as a new connection in Open-WebUI.

  • Under the Admin Panel, go to Settings -> Connections.
  • Use the "+" (plus) button to add a new connection under the OpenAI
  • For the URL, use "http://host.docker.internal:8000/api/v1"
  • For the password, the default password defined in BAG is "bedrock". You can always change this password in the BAG settings (see DEFAULT_API_KEYS)
  • Click the "Verify Connection" button and you should see "Server connection verified" alert in the top-right

Step 4: Start using Bedrock Base Models​

You should now see all your Bedrock models available!
