AWS Bedrock Provider Integration

Added support for AWS Bedrock as a new LLM provider:

• Anthropic Claude models
• Amazon Titan models (text & embeddings)
• AI21 Jurassic models

Key Changes

Added Bedrock provider implementation with model-specific handlers:

• Anthropic: Reused existing Anthropic provider code with Bedrock-specific modifications ( no actual changes)
• Titan: Added chat completion and embedding support
• AI21: Added completion and chat completion support
• Request/response mapping between Hub formats and Bedrock formats

Testing Notes

All tests pass using AWS credentials in us-east-1/2 regions Verified error handling for invalid credentials/models Tested non-streaming responses ( models in Bedrock don’t seem to have streaming types )

Review notes

The model ID from AWS link does not work consistently. Instead, use the Inference profile ARN or Inference profile ID from the cross-region reference tab as your model_id.
