Choosing the Model

Available Models

After thorough benchmarking, Unique has taken the decision to only vet the main GPT-5 model, as the output quality of mini and nano models did not prove to be up to our required standards.

Hence you can set the language model to the GPT-5 (2025-08-07) Azure model using the following model identifier : AZURE_GPT_5_2025_0807.

For the complete list of approved Azure models, please refere to Unique’s official list of supported models.

Model Restrictions

The GPT-5 model only accepts a temperature value of 1 when reasoning effort is enabled (i.e., set to any value other than none).

Important: The Unique toolkit no longer automatically overwrites the temperature setting. When reasoning effort is set to a value other than none (e.g., minimal, low, medium, or high), the space admin must manually set the temperature to 1 in the space configuration. Failing to do so may result in API errors.

Reasoning

GPT-5 models offer 4 levels of reasoning effort: minimal, low, medium, and high. Reasoning can also be disabled by setting the value to none.
For speed and performance purposes, Unique has set the model reasoning effort to minimal.
Please contact our Customer Success team to modify the reasoning effort settings.

Note on Code Execution Tool: When the code execution tool is enabled on a space, the GPT language model is switched to the Response API. In this mode, the reasoning effort parameter name changes from reasoning_effort to reasoning.effort. Space admins should ensure the correct parameter name is used in space configurations when the code execution tool is active.

Model Configuration in Spaces

For Spaces 2.0

Changing the Model to GPT-5 on Existing Spaces

Go to Space Management > Space > Configuration > Language Model.

Replace the existing model with AZURE_GPT_5_2025_0807.

Click Update to save the changes.

Creating New Spaces with GPT-5

For space creation with Spaces 2.0, you can refer to the space creation documentation.

Go to Space Management > Create Space > Unique AI Chat > Configuration > Language Model.

Set Language Model to AZURE_GPT_5_2025_0807.

Click Create to complete the space creation.

Editing Custom Spaces

Go to Space Management > Custom Space > AI Assistant > Edit.

Find the main language model configured in the json object, and replace the language model with AZURE_GPT_5_2025_0807.

Important:

• If the reasoning effort is set to any value other than none (e.g., minimal, low, medium, high), you must set the temperature to 1 on the Space 2.0 Configuration UI, or remove temperature in the JSON configuration on a Custom Space UI. The toolkit no longer overwrites this automatically.

• When the code execution tool is enabled, the model uses the Response API. In this case, the reasoning effort parameter in the additional LLM options must use the name reasoning.effort (with a dot) instead of reasoning_effort (with an underscore).
