- You can use it to have your research done in a few clicks, all the while using your favorite AI model.
- No, you can not set a default AI model for your search, even in the pro subscription, you can not.
- In this article, we have talked about the feature where Perplexity automatically switches to the best AI model according to your query.
Perplexity has earned its place in the AI roadmap; it is perceived as one of the best research tools out there. You can use it to have your research done in a few clicks, all the while using your favorite AI model. Perplexity gained more popularity recently due to thier collab with Airtel. They issued a one-year free subscription to all Airtel users, which worked well to bring in new subscribers on Perplexity. The biggest advantage of Perplexity is that you can switch between different AI models. However, there is no option to set a default AI model as your preferred choice. Is this by choice or just a simple error?

Optimized for Smooth Operation?
This particular feature is not much talked about, and not a lot of people actually care. However, some people actually care and they want to use a specific AI model for thier queries. I personally prefer to use ChatGPT for all my queries, but some might prefer Sonnet or Claude. In overall operation, Perplexity automatically switches the AI model based on the query you have asked. So we do save a lot of time using this particular feature, but do you need it?
Why this Feature can be Intentional
There are a couple of reasons why I believe that this feature is a production choice.
1. Since there are a lot of LLM choices, the default settings for them will make the UI more complex. In the current settings of Perplexity, it is faster and unified.

2. As Perplexity periodically updates the models powering its system, tying individual threads to a fixed default could introduce versioning conflicts or confusion.
3. Since the user needs to select thier preferred AI model every time, they became more aware of their queries and the models that can help them properly.
