Goal planning with Embabel and Ollama

This example shows the planner choosing between two routes to the same goal.

Both lookUpAnswer and generateAnswer produce an Answer, and the first one is declared cheaper. The planner tries the cheap route first, and when the lookup returns nothing it replans and takes the model route. The action costs, not a hand-written branch, decide the order.

Requirements

• Java 21+
• Maven 3.9+
• Ollama installed locally
• A pulled chat model such as llama3.1:8b

Steps for running this example in the shell

1. Start Ollama and pull the chat model:

ollama serve
ollama pull llama3.1:8b

2. Run the application:

mvn spring-boot:run

Output
