The library provides a unified interface (IChatClient) that works across different AI providers (Azure OpenAI, AWS Bedrock, Ollama), making it easy to switch providers without rewriting code. Key features include chat history management, system prompts for model behavior customization, function invocation that allows AI models to call your application methods, and built-in evaluation tools for testing AI responses. The library includes quality evaluators (equivalence, relevance, completeness) and safety evaluators (violence, sexual content, code vulnerabilities) that use Microsoft-trained models to assess AI outputs locally. Implementation requires minimal code: initialize a chat client, optionally configure chat options with tools/functions, and use streaming or standard response methods. ## Full article daily.dev links to this article rather than hosting it.
