Updates dev.langchain4j:langchain4j from 1.20.2 to 1.21.0

Release notes

Sourced from dev.langchain4j:langchain4j's releases.

1.21.0 and 1.21.0-beta31

Decision Models (experimental)

This release introduces decision models: a new model type that answers questions about an input with typed answers and probabilities instead of generated text. They are a fast, cheap fit for classification, routing, gating and grading.

  • DecisionModel API (#6469, #6543): ask yes/no, choice and scale questions in a single call and get the probability of each answer back. The first integration is TypeSafe. It also works with servers that speak the same /v1/systemone protocol, such as OpenRouter.
  • Decision Services (#6526): declare the questions as methods of a Java interface, as you would for AI Services. LangChain4j implements the interface and converts the answers to boolean, enums, Choice<E> or records.
  • Ready-made integrations (#6545): RoutingChatModel sends each request to the right chat model. There is also re-ranking for RAG (DecisionScoringModel), query routing, tool selection and input/output guardrails, and they all work with any DecisionModel.
  • Agentic router (#6561): DecisionRouterPlanner uses a decision model to choose which subagents handle a request.

All of these APIs are @Experimental and may change in future releases. Start with the Decision Models and Decision Services tutorials.
