Perplexity is taking a major step forward in AI service by integrating GPT 5.1 for its Pro and Max users. The company’s CEO, Aravind Srinivas, confirmed the upgrade on Friday. His announcement comes shortly after OpenAI revealed the new model.
The upgrade introduces two distinct versions of GPT 5.1. The first version, named 'Instant', emphasises speed and accessibility. It is designed for fast responses in everyday use. The second version, 'Thinking', focuses on deeper reasoning, more thorough explanation and clearer outputs.
Srinivas described the change as more than just an update. He said users of both Pro and Max tiers will gain richer, more natural dialogue experiences. The upgrade promises warmer conversational tone, better context awareness and fewer vague or generic answers.
Pro users now access GPT 5.1 Instant. Max users gain the option of Instant or Thinking. This move positions Perplexity as a serious contender in the AI-search and chat space. The company claims the upgrade gives its premium customers sharper reasoning, tailored personalisation and dynamic responses.
Besides the tech update, this move has strategic importance. With GPT 5.1 live on the platform, Perplexity gains a competitive edge over other players that have not yet adopted the latest model. The firm has a large number of users already and it considers this improvement as a way to make the users more involved through the whole process.
The integration also signals a shift in how AI assistants serve users. Instant mode suits users who need quick facts, brainstorming or rapid content. Thinking mode suits users engaged in complex research, detailed tasks or professional work. That dual-mode approach may set a new standard for AI services.
Srinivas also dropped a hint about what lies ahead. He mentioned an upcoming model codenamed “Kimi K2”. Though details remain limited, it shows Perplexity’s ambition to keep pushing its AI offering.
Perplexity GPT 5.1 upgrade arrives at a time when the need for intelligent AI conversations is increasing. The firm asserts its position in the AI space by introducing two custom-made versions and focusing on the quality of dialogue and reasoning power. The upgrade allows Pro and Max users to instantly utilize the advanced AI, while it also opens the door for more new ideas in the future.
