base on Koog is the official Kotlin framework for building predictable, fault-tolerant and enterprise-ready AI agents across all platforms – from backend services to Android and iOS, JVM, and even in-browser environments. Koog is based on our AI products expertise and provides proven solutions for complex LLM and AI problems # Koog [](https://kotlinlang.org/docs/components-stability.html) [](https://search.maven.org/artifact/ai.koog/koog-agents) [](https://github.com/JetBrains#jetbrains-on-github) [](http://kotlinlang.org) [](https://github.com/JetBrains/koog/actions?query=branch%3Amain) [](LICENSE.txt) [](https://docs.koog.ai) [](https://kotlinlang.slack.com/messages/koog-agentic-framework/) ## Overview Koog is a Kotlin-based framework designed to build and run AI agents entirely in idiomatic Kotlin. It lets you create agents that can interact with tools, handle complex workflows, and communicate with users. ### Key features Key features of Koog include: - **Multiplatform development**: Deploy agents across JVM, JS, WasmJS, Android, and iOS targets using Kotlin Multiplatform. - **Reliability and fault-tolerance**: Handle failures with built-in retries and restore the agent state at specific points during execution with the agent persistence feature. - **Intelligent history compression**: Optimize token usage while maintaining context in long-running conversations using advanced built-in history compression techniques. - **Enterprise-ready integrations**: Utilize integration with popular JVM frameworks such as Spring Boot and Ktor to embed Koog into your applications. - **Observability with OpenTelemetry exporters**: Monitor and debug applications with built-in support for popular observability providers (W&B Weave, Langfuse). - **LLM switching and seamless history adaptation**: Switch to a different LLM at any point without losing the existing conversation history, or reroute between multiple LLM providers. - **Integration with JVM and Kotlin applications**: Build AI agents with an idiomatic, type-safe Kotlin DSL designed specifically for JVM and Kotlin developers. - **Model Context Protocol integration**: Use Model Context Protocol (MCP) tools in AI agents. - **Knowledge retrieval and memory**: Retain and retrieve knowledge across conversations using vector embeddings, ranked document storage, and shared agent memory. - **Powerful Streaming API**: Process responses in real-time with streaming support and parallel tool calls. - **Modular feature system**: Customize agent capabilities through a composable architecture. - **Flexible graph workflows**: Design complex agent behaviors using intuitive graph-based workflows. - **Custom tool creation**: Enhance your agents with tools that access external systems and APIs. - **Comprehensive tracing**: Debug and monitor agent execution with detailed, configurable tracing. ### Available LLM providers and platforms The LLM providers and platforms whose LLMs you can use to power your agent capabilities: - Google - OpenAI - Anthropic - DeepSeek - OpenRouter - Ollama - Bedrock ### Quickstart example To help you get started with AI agents, here is a quick example: ```kotlin fun main() = runBlocking { // Before you run the example, assign a corresponding API key as an environment variable. val apiKey = System.getenv("OPENAI_API_KEY") // or Anthropic, Google, OpenRouter, etc. val agent = AIAgent( executor = simpleOpenAIExecutor(apiKey), // or Anthropic, Google, OpenRouter, etc. systemPrompt = "You are a helpful assistant. Answer user questions concisely.", llmModel = OpenAIModels.Chat.GPT4o ) val result = agent.run("Hello! How can you help me?") println(result) } ``` ## Using in your projects ### Supported targets Currently, the framework supports the JVM, JS, WasmJS and iOS targets. On JVM, JDK 17 or higher is required to use the framework. Please check the [libs.versions.toml](gradle/libs.versions.toml) to know more about the Koog dependencies. ### Gradle (Kotlin DSL) 1.
