AgentHub – the only SDK you need to connect to LLMs (github.com)

The newly launched AgentHub SDK offers a streamlined, unified interface for developers to connect with leading Large Language Models (LLMs) like Gemini 3, Claude 4.5, and GPT-5.2. By providing an intuitive integration environment, AgentHub aims to simplify the development of AI agents, making it particularly significant for developers seeking to build more sophisticated applications without the hassle of switching between different SDKs. The SDK’s capabilities include automatic handling of complex multi-step tool calls, which enhances performance consistency, as well as a lightweight tracing feature that bolsters debugging and auditing processes. AgentHub facilitates seamless interaction with LLMs, featuring a main class called AutoLLMClient, which supports stateless and stateful response streaming. This flexibility allows developers to maintain state across interactions, improving application fluidity. The SDK is available for installation via PyPI and npm, encourages configuration through a structured UniConfig object, and provides tracing and monitoring tools for enhanced debugging. With these features, AgentHub not only enhances usability but also empowers a new level of efficiency in LLM integration for both novice and experienced AI developers.
