Taiat (TypeScript AI Agent Toolkit) is a lightweight, extensible framework for building autonomous AI agents in Node.js and browser environments. It enables developers to define agent behaviors, integrate with large language model APIs such as OpenAI and Hugging Face, and orchestrate multi-step tool execution workflows. The framework supports customizable memory backends for stateful conversations, tool registration for web searches, file operations, and external API calls, as well as pluggable decision strategies. With taiat, you can rapidly prototype agents that plan, reason, and execute tasks autonomously, from data retrieval and summarization to automated code generation and conversational assistants.
