About

Eino is an LLM application development framework in Go that draws on LangChain and Google ADK and follows Go conventions. It provides components such as chat models, tools, retrievers and chat templates, with official OpenAI and Ollama implementations. The Agent Development Kit builds tool-using agents with multi-agent coordination and interrupt/resume for human-in-the-loop, and graphs can be exposed as tools for agents.

Use cases: agent-orchestration, backend-development

    Done for you

    Rather not set it up yourself?

    Chalk Labs scopes, builds and runs agents for your team: the task audit, the eval harness, the integrations and the weekly ops report. Fixed scope, priced before we start.
