   • Navigate to your Azure OpenAI resource
   • Copy your endpoint URL (it looks like https://your-company.openai.azure.com)

2. Construct the complete API URL

   • Add /openai/v1 to the end of your endpoint URL
   • Your complete URL should look like: https://your-company.openai.azure.com/openai/v1

3. Configure in Opik

   • In Opik, go to Workspace Settings > AI Providers
   • Click “Add Configuration”
   • Select “vLLM / Custom provider” from the dropdown
   • Enter your complete URL in the URL field: https://your-company.openai.azure.com/openai/v1
   • Add your Azure OpenAI API key in the API Key field
   • In the Models section, list the models you have deployed in Azure (e.g., gpt-4o)
   • Click Save to store the configuration

Once saved, you can use your Azure OpenAI models directly from Online Scores and the Playground.

Vertex AI

Option A: Setup via gcloud CLI

1. Create a Custom IAM Role

$
gcloud iam roles create opik \
>
  --project=<my-project> \
>
  --title="Opik" \

Final Step: Connect Opik to Vertex AI

1. In Opik, go to Workspace Settings > AI Providers
2. Click “Add Configuration”
3. Set:

• Provider: Vertex AI
• Location: Your model region (e.g., us-central1)
• Vertex AI API Key: Paste the full contents of the opik-key.json file here

4. Click Add configuration

Amazon Bedrock

Amazon Bedrock provides access to foundation models from leading AI companies like AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon through AWS. Opik connects to Bedrock using the OpenAI Chat Completions API. Only models that support this API format will work with the Opik Playground. Check the supported models documentation to verify compatibility before configuring.

Prerequisites

Before configuring Bedrock in Opik, ensure you have:

1. An active AWS account with Bedrock access
2. Model access enabled for the models you want to use (see AWS documentation)
3. An API key or credentials configured for Bedrock access

Configuring Bedrock in Opik

1. In Opik, go to Workspace Settings > AI Providers
2. Click “Add Configuration”
3. Select “Bedrock” from the provider dropdown
4. Fill in the configuration:
   • Provider name: A unique identifier for this provider instance (e.g., “Bedrock us-east-1”)
   • URL: Your Bedrock endpoint URL (see format below)
   • API Key: Your AWS Bedrock API key (see AWS documentation for setup instructions)
   • Models list: Comma-separated list of models you want to use (e.g., us.anthropic.claude-3-5-sonnet-20241022-v2:0,us.meta.llama3-2-3b-instruct-v1:0)
   • Custom headers (optional): Add any additional HTTP headers required by your configuration
5. Click Add configuration to save

Bedrock URL Format by Region

Bedrock endpoints follow this pattern: https://bedrock-runtime.<region>.amazonaws.com/openai/v1

Examples by Region:

• US East 1: https://bedrock-runtime.us-east-1.amazonaws.com/openai/v1
• US West 2: https://bedrock-runtime.us-west-2.amazonaws.com/openai/v1
• Europe West 1 (Ireland): https://bedrock-runtime.eu-west-1.amazonaws.com/openai/v1
• Europe Central 1 (Frankfurt): https://bedrock-runtime.eu-central-1.amazonaws.com/openai/v1
• Asia Pacific (Tokyo): https://bedrock-runtime.ap-northeast-1.amazonaws.com/openai/v1
• Asia Pacific (Singapore): https://bedrock-runtime.ap-southeast-1.amazonaws.com/openai/v1

Multiple Bedrock Instances

You can configure multiple Bedrock providers for different AWS regions or accounts. Each instance appears separately in the provider dropdown, making it easy to switch between configurations in the Playground and Online Evaluation.

Ollama

Opik connects to Ollama using the OpenAI-compatible API, so you can use Ollama models for all LLM operations.

Configuring Ollama in Opik

1. In Opik, go to Workspace Settings > AI Providers
2. Click “Add configuration”
3. Select “Ollama” from the provider dropdown
4. Fill in:
   • Provider name: A name for this instance (e.g., “Ollama local”)
   • URL: Base URL of your Ollama instance, ending with /v1 (e.g., http://localhost:11434/v1)
   • API Key (optional): Leave blank unless your Ollama instance requires authentication
   • Use “Test connection” to verify Opik can reach the instance, then “Discover models” to load the model list
5. Click Save to store the configuration

You can configure multiple Ollama instances with different provider names and URLs.

vLLM / Custom Provider

Use this option to add any other OpenAI API-compliant provider such as vLLM, etc. You can configure multiple custom providers, each with their own unique name, URL, and models.

Configuration Steps

1. Provider Name: Enter a unique name to identify this custom provider (e.g., “vLLM Production”, “Ollama Local”, “Azure OpenAI Dev”)
2. URL: Enter your server URL, for example: http://host.docker.internal:8000/v1
3. API Key (optional): If your model access requires authentication, enter the API key. Otherwise, leave this field blank.
4. Models: List all models available on your server. You’ll be able to select one of them for use later.
5. Custom Headers (optional): Add any additional HTTP headers required by your custom endpoint as key-value pairs.

Custom Headers

Some custom providers may require additional HTTP headers beyond the API key for authentication or routing purposes. You can configure these headers using the “Custom headers” section:

• Click ”+ Add header” to add a new header
• Enter the header name (e.g., X-Custom-Auth, X-Request-ID)
• Enter the header value
• Add multiple headers as needed
• Use the trash icon to remove headers

Common use cases for custom headers:

• Custom authentication: Additional authentication tokens or headers required by your infrastructure
• Request routing: Headers for routing requests to specific model versions or deployments
• Metadata tracking: Custom headers for tracking or logging purposes
• Enterprise features: Headers required for enterprise proxy configurations

Managing Multiple Custom Providers

Once you’ve configured multiple custom providers, you can:

• Edit any custom provider by selecting it from the provider dropdown in the configuration dialog
• Delete custom providers that are no longer needed
• Switch between different custom providers in the Playground and Automation Rules

Each custom provider appears as a separate option in the provider dropdown, making it easy to work with multiple self-hosted or custom LLM deployments.

API Key Security

API keys are encrypted and stored securely. Only the name and provider type are visible after configuration.

Troubleshooting

• Authentication Errors: Ensure your API key is valid and hasn’t expired
• Access Denied: Check that your API key has the required permissions for the models you’re trying to use
• Rate Limiting: Adjust your request frequency or contact your provider to increase limits
