To empower people to unlock the joy of discovery, feel the wonder of creation and better harness the world’s knowledge, today we’re improving how the world benefits from the web by reinventing the tools billions of people use every day, the search engine and the browser.

Today, we’re launching an all new, AI-powered Bing search engine and Edge browser, available in preview now at Bing.com, to deliver better search, more complete answers, a new chat experience and the ability to generate content. We think of these tools as an AI copilot for the web.

“AI will fundamentally change every software category, starting with the largest category of all – search,” said Satya Nadella, Chairman and CEO, Microsoft. “Today, we’re launching Bing and Edge powered by AI copilot and chat, to help people get more from search and the web.”

The new Bing experience is a culmination of four technical breakthroughs:

• Next-generation OpenAI model. We’re excited to announce the new Bing is running on a new, next-generation OpenAI large language model that is more powerful than ChatGPT and customized specifically for search. It takes key learnings and advancements from ChatGPT and GPT-3.5 — and it is even faster, more accurate and more capable.

• Microsoft Prometheus model. We have developed a proprietary way of working with the OpenAI model that allows us to best leverage its power. We call this collection of capabilities and techniques the Prometheus model. This combination gives you more relevant, timely and targeted results, with improved safety.

• Applying AI to core search algorithm. We’ve also applied the AI model to our core Bing search ranking engine, which led to the largest jump in relevance in two decades. With this AI model, even basic search queries are more accurate and more relevant.

• New user experience. We’re reimagining how you interact with search, browser and chat by pulling them into a unified experience. This will unlock a completely new way to interact with the web.

The new Bing is available today in a limited preview on desktop, and everyone can visit Bing.com today to try sample queries and sign up for the waitlist. We’re going to scale the preview to millions in the coming weeks. A mobile experience will also be in preview soon.
