Switching Custom GPTs to Reasoning Models (o1/o3) for Better Results
Press play on the video. It'll jump straight to the section that answers the
title above — no need to watch the full video.
A guide to configuring Custom GPTs to use the latest models like o1 or o3 to solve complex coding and logic problems.
When to Use the o1/o3 Series
Use reasoning models (o1/o3) if your Custom GPT focuses on heavy-duty tasks such as solving mathematical problems, complex coding, or logic that requires deep reasoning, as opposed to GPT-4o which is optimized for speed.
User Flexibility
Even if you set a default model in the 'Configure' section, end users still have the option to manually switch models at the top of the chat screen if they require different results.
