## Space Management Default Model

When users commit a prompt in a Space where the Assistant contains more than one module, the system will need to choose which module to generate a response. Module selection is done with the function calling approach of OpenAI ( [https://platform.openai.com/docs/guides/function-calling](https://platform.openai.com/docs/guides/function-calling))

In this release the default `languageModel` module used for module selection is changed from `AZURE_GPT_35_TURBO_0125` to `AZURE_GPT_4o_2024_1120`.
