  • OpenAI CEO Sam Altman said ChatGPT and GPT-3.5 are helping boost Microsoft’s “new Bing” search engine.
  • The rise of OpenAI’s ChatGPT bot has fueled the competition in Big Tech to boost search tools.
  • Google announced its own AI tool called “Bard,” with plans for a public rollout in coming weeks.

What’s under the hood of Microsoft’s flashy “new Bing” search engine?

OpenAI’s CEO Sam Altman said that the artificial-intelligence company’s megahit ChatGPT tool and GPT-3.5 are helping drive the search engine that Microsoft announced Tuesday.

Microsoft is touting “new Bing” as unlike any search engine currently available.

Microsoft executive Yusuf Mehdi said that the advanced search tool “is running on a new, next-generation OpenAI large language model that is more powerful than ChatGPT,” and that it “takes key learnings and advancements from ChatGPT and GPT-3.5,” according to a blog post Tuesday

Whereas GPT-3 — the language model on which ChatGPT is built — has 175 billion parameters, GPT-4 is expected to have 100 trillion parameters. Microsoft said Bing was running on a “new next-generation language model,” but stopped short of calling it GPT-4.

The comments reveal the latest chapter of Microsoft’s partnership with OpenAI, which said last month that the tech giant would make a “multi-billion dollar investment” in OpenAI’s technology.  

The announcement also comes as the battle heats up among Big Tech giants to use generative AI technology to boost their search functions. At Tuesday’s event, Microsoft also revealed its closely anticipated announcement that its own search tool Bing will now use OpenAI’s technology to boost searches. Among other things, it will incorporate a chat function that will allow users to fine tune their searches, according to the company. 

The development marks a turning point for online searches, a feature of the Internet that’s “remained fundamentally the same since the last major inflection,” Mehdi said at Microsoft’s event at Redmond, Washington. 

Insider’s Ashley Stewart previously reported that Microsoft was expected to reveal that Bing would be upgraded with OpenAI’s technology.

OpenAI’s ChatGPT created popular access to a type of technology that’s been long familiar to computer science and data analytics experts. But the fervor around the tool’s adoption by the general public appears to be accelerating efforts to harness the technology for specialized uses.

Google, where ChatGPT’s sudden rise is reportedly regarded as a “code red” over fears about how it may affect its search engine, on Monday revealed its own counterpart called “Bard.” CEO Sundar Pichai wrote in a blog post that the company plans to open it up soon to the public.
