· Updated

Perplexity integrated OpenAI's new GPT-5.5 model as a selectable option for Max subscribers and the default orchestrator for its Computer platform. By using the latest frontier model to manage multi-step tasks, Perplexity is prioritizing the model's improved self-correction and agentic reasoning for its power users.

Perplexity, an AI-powered answer engine, integrated OpenAI's GPT-5.5 model across its high-end tiers. The model is now a selectable reasoning engine for Max subscribers and serves as the default orchestration model—the logic layer that coordinates tools and sub-tasks—for the Perplexity Computer interface.

This update mirrors OpenAI's reported 56% token efficiency gain when running the new model for complex computer-use tasks. By making it the default orchestrator, Perplexity is shifting its backend logic to leverage specific optimizations for agentic loops and multi-step goal handling within its Computer environment.

You can now use GPT-5.5 to drive automated research, coding, and app navigation through the Computer platform. This integration matches GitHub Copilot's GPT-5.5 launch — part of a broader shift toward autonomous reasoning models that resolve real-world challenges previous GPT versions could not handle.

Still wondering? A few quick answers below.

Access to GPT-5.5 on Perplexity depends on your subscription tier. The model is available as a selectable chat engine exclusively for Max subscribers. However, both Pro and Max subscribers can use GPT-5.5 indirectly, as it has been rolled out as the default orchestration model for the Perplexity Computer platform.

As the default orchestration model, GPT-5.5 acts as the central logic engine for Perplexity Computer. It manages complex, multi-step tasks by coordinating between various tools and models to execute workflows like research or coding. This leverages the model's specific optimizations for agentic loops and self-correction.

A Perplexity Max subscription costs $200 per month. This high-end tier provides full access to frontier models like GPT-5.5 for direct chat interactions. It also includes advanced features for Perplexity Computer, such as higher usage limits and priority access to the latest orchestration engines for automated digital tasks.

No, GPT-5.5 is not available to free users on the Perplexity platform. The model is currently restricted to paid tiers, with direct chat access reserved for Max subscribers. Pro subscribers can only access the model's capabilities when it functions as the background orchestrator for tasks within the Perplexity Computer interface.
