What commenters say

• The Instant model is less accurate than the Thinking model, but faster and more suitable for certain use cases.
• The use of the term 'cringe' to describe the tone of GPT-5.2 is a common critique, and its usage is not limited to Gen Z.
• Some users find the Instant model to be 'slop tier' and prefer the Thinking model for its more palatable tone and useful responses.
• Providing a 'Think longer and give me a better answer' button could be a useful feature to allow users to switch between the Instant and Thinking models.
• The complexity of the model options and differentiation can be confusing for users, and a 'sane defaults but configurable' approach may be a better solution.
• The default model for most users should be the Thinking model, as the Instant model can provide misleading or inaccurate responses.
• The model selection and options should be hidden from the user interface, and instead, allow power users to access them through configuration options.
• The product split between different models and options can be a brand harm, and a post-hoc analysis to determine the best default model for users may be necessary.
