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 refer 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).

Note: Since Unique toolkit 1.70.1 (April 2026), the temperature is resolved automatically: when an active reasoning effort is set, the platform forces the temperature to 1 before the request is sent. A manually configured temperature has no effect in that case and does not cause API errors.

Reasoning

GPT-5 models offer 4 levels of reasoning effort: minimal, low, medium, and high. The value none is not supported on GPT-5 (it exists from GPT-5.1 onward) — the lightest setting is minimal. If an unsupported value such as none is configured, the platform logs a warning and falls back to the lightest supported effort.

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 Responses API. No configuration change is needed: the platform automatically translates the reasoning_effort key in the additional LLM options into the Responses reasoning.effort parameter. Also note that the code interpreter cannot run at minimal effort — it is automatically raised to low.

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, the platform automatically forces the temperature to 1 (since toolkit 1.70.1) — you no longer need to set it manually. On a Custom Space you can simply remove the temperature from the JSON configuration.

• When the code execution tool is enabled, the model uses the Responses API. The reasoning_effort key in the additional LLM options keeps working: it is automatically translated to reasoning.effort (with a dot) on the wire.
