⚙️ Configuration

Configure your OpenAI API key and AI options in application.properties:

spring.application.name=gen-ai-demo
spring.ai.openai.api-key=${OPENAI_API_KEY}
spring.ai.openai.chat.options.model=gpt-4.1
server.port=8899
logging.level.org.springframework.ai.chat.client.advisor=DEBUG

Replace ${OPENAI_API_KEY} with your OpenAI API key.
