Key Highlights​

Agent Gateway (A2A)​


This release introduces A2A Agent Gateway for LiteLLM, allowing you to invoke and manage A2A agents with the same controls you have for LLM APIs.

As a LiteLLM Gateway Admin, you can now do the following:

  • Request/Response Logging - Every agent invocation is logged to the Logs page with full request and response tracking.
  • Access Control - Control which Team/Key can access which agents.

As a developer, you can continue using the A2A SDK, all you need to do is point you A2AClient to the LiteLLM proxy URL and your API key.

Works with the A2A SDK:

from a2a.client import A2AClient

client = A2AClient(
    base_url="http://localhost:4000",  # Your LiteLLM proxy
    api_key="sk-1234"                   # LiteLLM API key
)

response = client.send_message(
    agent_id="my-agent",
    message="What's the status of my order?"
)

Customer (End User) Usage UI​

Users can now filter usage statistics by customers, providing the same granular filtering capabilities available for teams and organizations.

Details:

  • Filter usage analytics, spend logs, and activity metrics by customer ID
  • View customer-level breakdowns alongside existing team and user-level filters
  • Consistent filtering experience across all usage and analytics views
