Bedrock

Quick Start

1. Define Guardrails on your LiteLLM config.yaml

Define your guardrails under the guardrails section

model_list:
  - model_name: gpt-3.5-turbo
    litellm_params:
      model: openai/gpt-3.5-turbo
      api_key: os.environ/OPENAI_API_KEY

guardrails:
  - guardrail_name: "bedrock-pre-guard"
    litellm_params:
      guardrail: bedrock  # supported values: "aporia", "bedrock", "lakera"
      mode: "during_call"
      guardrailIdentifier: ff6ujrregl1q # your guardrail ID on bedrock
      guardrailVersion: "DRAFT"         # your guardrail version on bedrock
  

Supported values for mode

• pre_call Run before LLM call, on input
• post_call Run after LLM call, on input & output
• during_call Run during LLM call, on input Same as pre_call but runs in parallel as LLM call. Response not returned until guardrail check completes

2. Start LiteLLM Gateway

litellm --config config.yaml --detailed_debug

3. Test request

Langchain, OpenAI SDK Usage Examples

Expect this to fail since since ishaan@berri.ai in the request is PII

curl -i http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-npnwjPQciVRok5yNZgKmFQ" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [
      {"role": "user", "content": "hi my email is ishaan@berri.ai"}
    ],
    "guardrails": ["bedrock-guard"]
