JetBrains has launched Koog for Java, bringing its AI agent framework to the JVM with a fully idiomatic Java API. The framework lets Java teams build AI agents directly in existing backends without Python microservices. Key features include multiple workflow strategies (functional, graph-based, and GOAP planning), Spring Boot integration, support for major LLM providers (OpenAI, Anthropic, Google, DeepSeek, Ollama), fault-tolerant persistence (Postgres, S3, disk) that resumes from the exact failure point, OpenTelemetry observability with Langfuse and W&B Weave support, history compression to manage token costs, and fine-grained Java thread pool control via ExecutorService configuration.
