Within hours of OpenAI announcing GPT 5.1 for the masses, rival AI firm Perplexity jumped on the hype train in extending the benefits of the newest GPT model to its paid subscribers. Perplexity’s CEO, Aravind Srinivas, took to X (formerly Twitter) to confirm the arrival of the latest GPT model on its AI search engine. Perplexity AI has integrated OpenAI’s newly launched GPT-5.1 models, making them available exclusively to its Pro and Max subscribers.
Announced by Perplexity CEO Aravind Srinivas, this upgrade promises more natural, personalised conversations and sharper reasoning capabilities, thus positioning Perplexity as a frontrunner in conversational AI tools. As users demand smarter, faster interactions, the Perplexity GPT-5.1 integration arrives amid OpenAI’s broader push for enhanced model variants, all in the hope of outpacing rivals like Google Gemini and Anthropic’s Claude.
Perplexity integrates GPT 5.1 into its search engine
Srinivas shared the news via X, highlighting immediate access for premium users. This follows OpenAI’s global rollout of GPT-5.1, which includes refinements in intelligence, adaptability, and communication styles. For Perplexity’s 10 million+ monthly users, this update makes search answers more dynamic and context-aware, which makes it ideal for professionals, researchers, and casual users alike.
Key features of GPT-5.1 on Perplexity:
GPT-5.1 debuts in two tailored variants:
GPT-5.1 Instant: This model is optimised for everyday use. It’s warmer, more conversational, and excels at following user instructions. As ChatGPT’s go-to model, it delivers quicker responses without losing clarity. This makes it perfect for rapid queries like quick facts or brainstorming.
GPT-5.1 Thinking: This model is built for complex tasks. It offers advanced reasoning with clearer explanations, fewer vague terms, and adaptive “thinking time” for tough problems.
OpenAI highlights that these models reduce jargon and enhance personalisation through eight tone presets – from friendly to quirky. One can also fine-tune sliders for conciseness and warmth.
Perplexity plan details after GPT-5.1 update
With the GPT-5.1 integration now live, Perplexity Pro costs $20/month, whereas Perplexity Max ends up costing $40/month for subscribers. Free tier users may see limited access later. Srinivas also confirmed, “Kimi K2 is coming very soon.” Kimi K2 is the latest AI model from Moonshot AI.
