Understanding What’s the Best AI Model Using Perplexity?
Determining what’s the best AI model using Perplexity starts with grasping its unique multi-model setup. Unlike single-model tools, Perplexity dynamically routes queries to specialised LLMs based on task needs like search, coding, or multimodal analysis[1][2]. This adaptive layer ensures you get the optimal response every time, blending speed with cited accuracy.
In late 2025, Perplexity’s free tier rotates models like Mistral Large 2 for quick answers and Gemini 2.5 Flash for visuals, while Pro unlocks heavyweights like GPT-5 and Claude 4.5[1].
