DeepSearcher

Judgement

What it is

Template or starter

What it does

A Python reference project that combines LLMs with a vector database such as Milvus to search, reason over and write reports on private documents.

Adopt it when

You want a starting point for a deep-research style agent over your own documents.

Watch out

No releases, a demo-style codebase from a vendor promoting Milvus, and quiet since September 2026.

   LangChain4j langchain4j

   LangChain4j is an idiomatic, open-source Java library for building LLM-powered applications on the JVM. It offers a unified API over popular LLM providers and vector stores, and makes implementing tool calling (including MCP support), agents and RAG easy. It integrates seamlessly with enterprise Java frameworks like Quarkus and Spring Boot.

   Framework or platform Production-ready You are adding LLM features to a Java or Kotlin application and want to stay on the JVM.
