Quick Start​

Model Format to LiteLLM​

To call a bedrock agent through LiteLLM, you need to use the following model format to call the agent.

Here the model=bedrock/agent/ tells LiteLLM to call the bedrock InvokeAgent API.

Model Format to LiteLLM
bedrock/agent/{AGENT_ID}/{ALIAS_ID}

Example:

  • bedrock/agent/L1RT58GYRW/MFPSBCXYTW
  • bedrock/agent/ABCD1234/LIVE

You can find these IDs in your AWS Bedrock console under Agents.

LiteLLM Python SDK​

Basic Agent Completion
import litellm

# Make a completion request to your Bedrock Agent
response = litellm.completion(
    model="bedrock/agent/L1RT58GYRW/MFPSBCXYTW",  # agent/{AGENT_ID}/{ALIAS_ID}
    messages=[
        {
            "role": "user", 
            "content": "Hi, I need help with analyzing our Q3 sales data and generating a summary report"
        }
    ],
)

print(response.choices[0].message.content)
print(f"Response cost: ${response._hidden_params['response_cost']}")
Streaming Agent Responses
import litellm

# Stream responses from your Bedrock Agent
response = litellm.completion(
    model="bedrock/agent/L1RT58GYRW/MFPSBCXYTW",
    messages=[
        {
            "role": "user",
            "content": "Can you help me plan a marketing campaign and provide step-by-step execution details?"
        }
    ],

)

for chunk in response:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
