Perplexity Pro gives you access to the latest AI models from OpenAI and Anthropic, as well as other companies and includes both proprietary and open sourced models.

Here’s a quick overview of each model currently included—the list evolves as models and search modes update.

Search modes and models

Pro Search

Pro search uses your default or baseline model and performs an in depth internet search, granting you 3x the amount of sources. You can pick an advanced model when performing a Pro Search of your choice. The latest advanced models we support are:

"Best" mode

"Best" is optimized for speed, web browsing and taking the decision-making out of your hands when it comes to selecting a model. It’s fine-tuned to deliver fast, accurate answers and will automatically select the most suitable model for your query.

Pro Search Models

GPT-4.1

This model is designed for complex problem-solving across domains, with a strong focus on coding, instruction following, and handling large context windows.

Claude 4.0 Sonnet

Sonnet 4.0 is one of the most advanced large language model (LLM) available, particularly excelling at handling nuanced language tasks with a strong balance of speed and accuracy.

Sonar Large

Built on the LlaMa 3.1 70B open-source model, Sonar is trained in-house to work seamlessly with Perplexity’s search engine, making it a perfect fit for our cutting-edge search tech.

Grok 3 Beta

Grok 3 Beta, the latest advanced reasoning model from xAI, excels in complex math, science and coding tasks.

Gemini 2.5 Pro

Google’s latest and most advanced generative AI model, introduced in March 2025, represents a significant leap in AI reasoning, coding, and multimodal capabilities

Reasoning Models

R1 1776

A post-trained version of the DeepSeek-R1 model, developed by Perplexity AI. Its primary goal is to provide uncensored, unbiased, and factual information, especially on topics that are often subject to political or cultural censorship

OpenAI's o3

o3 is part of OpenAI’s “o-series” of models, specifically engineered for advanced logical reasoning and complex problem-solving—surpassing standard generative models like GPT-4o

o3-pro (only available to Max subscribers)

OpenAI's Most Powerful Reasoning Model, o3-pro is the top-tier variant in OpenAI’s o-series, offering the highest performance and depth of reasoning

Claude Sonnet 4.0 Thinking

Sonnet 4.0 is one of the most advanced large language model (LLM) available, particularly excelling at handling nuanced language tasks with a strong balance of speed and accuracy.

Claude 4.0 Opus Thinking (only available to Max subscribers)

Opus 4 is Anthropic’s flagship, most advanced model, built for the most demanding reasoning and agentic tasks.

How do I choose the right model?

The best way to figure out which model works for you is to test them out. Try comparing your queries across different models and see which one suits your needs best. It all comes down to what you’re looking to achieve.

What’s a token?

A token is a small chunk of text that AI models break down to process. Think of tokens as building blocks that help AI understand and generate language. You can use a tokenizer to see how many tokens a given piece of text contains.

Are there any guidelines for using third-party models like Claude or GPT?

No, you can use these models just as you would in their original platforms.

How do I know which model to pick for my task?

While all up to date LLMs for the most part achieve similar performance on standard benchmarks, Perplexity's choice of models have distinct operational strengths optimized for web search use case.
