Configure the AI Chat Support

Obeo Enterprise for SysON has optional support for AI Chat, but it is disabled by default. Note that if you are using a custom application based on Obeo Enterprise for SysON instead of Obeo Enterprise for SysON itself, make sure it includes the fr.obeo.enterprise.syson:oe4syson-ai-chat module on the backend.

To enable AI Chat support, you will need an OpenAI API key. Then make sure the backend is started with these system properties

spring.ai.chat.client.enabled=true
spring.ai.model.chat=openai
spring.ai.openai.api-key=YOUR_KEY # Replace with your OpenAI API Key

By default, the OpenAI model used is gpt-5-mini. You can choose to select another one from the list of OpenAI models using their model ID.

Note however that some models, in particular starting from GPT 5.6, require an additional configuration to work. For example if you want to use GPT 5.6 Terra (Model ID gpt-5.6-terra):

spring.ai.openai.chat.model=gpt-5.6-terra
spring.ai.openai.chat.reasoning-effort=none
