Microsoft has provided some particulars about Prometheus, the proprietary AI mannequin it created to combine ChatGPT-like performance into Bing search.
Microsoft has already mentioned the brand new Bing is “rather more highly effective” than OpenAI’s GPT-3.5 AI mannequin behind ChatGPT. Public experimentation, nonetheless, rapidly confirmed the chatbot function was liable to sudden outbursts, which prompted Microsoft to restrict the variety of “chat turns” to 5 per session to cease it turning into confused.

Now, Microsoft’s CVP of search and AI, Jordi Ribas, has shared some particulars about Prometheus — Microsoft’s proprietary mannequin that meshes Bing with OpenAI’s GPT mannequin to generate extra related leads to Bing — and the way it went about constructing the brand new Bing.
Ribas’ clarification comes as customers found that Microsoft had been testing Sydney (the inner codename for Bing Chat) with customers in India in late 2021. Customers there reported in November 2022 that Sydney was “impolite” in virtually precisely the identical method customers discovered it to be after Microsoft launched the brand new Bing.
Based on Ribas, OpenAI shared its “recreation altering” post-GPT-3.5 mannequin with Microsoft in summer time 2022. Microsoft president Brad Smith mentioned it was proven the OpenAI expertise “early final summer time” in his blogpost about Microsoft’s “accountable AI”.
OpenAI opened up ChatGPT to the world in November whereas Microsoft was reportedly in talks to speculate $10 billion in OpenAI in December, which it confirmed in late January. It then launched the brand new Bing on February 7, a day after Google rushed out its ChatGPT rival, Bard.
“Seeing this new mannequin impressed us to discover methods to combine the GPT capabilities into the Bing search product, in order that we may present extra correct and full search outcomes for any question together with lengthy, complicated, pure queries,” explains Ribas.
As Ribas factors out, giant language fashions like GPT-3.5 are skilled on knowledge as much as a given cut-off date. In ChatGPT’s case, its coaching knowledge stopped sooner or later in 2021. To make the consumer expertise “richer, extra related and correct,” Microsoft determined to mix it with Bing’s back-end through Prometheus.
Prometheus combines Bing index, rating, and reply outcomes with the model of GPT that Bing makes use of to ship the Chat reply, based on Ribas.
“Prometheus leverages the ability of Bing and GPT to generate a set of inner queries iteratively by a part referred to as Bing Orchestrator, and goals to supply an correct and wealthy reply for the consumer question inside the given dialog context. All inside a matter of milliseconds. We discuss with this Prometheus-generated reply because the Chat reply,” explains Ribas.
Ribas provides that Bing search outcomes, based mostly on consumer search queries and chats, feed contemporary info to Prometheus to assist it reply latest questions and scale back inaccuracies. The method is known as “grounding” — a way Google used when it developed a big language mannequin for clever robots. In Bing’s case, the GPT language mannequin is grounded in Bing knowledge, which is how Bing provides citations to Bing Chat responses.
“Although grounding is a exceptional innovation, it’s a new expertise and we want to consider how we apply it responsibly, together with additional decreasing inaccuracies and stopping offensive and dangerous content material. That is why a key objective of the brand new Bing preview is to gather consumer suggestions to assist us enhance Prometheus additional,” explains Ribas.
To enhance chat reply accuracy, Microsoft is planning to extend the grounding knowledge it sends to the mannequin by fourfold.
Ribas additionally says the Bing group had been divided over the way it ought to combine chat into the acquainted search question and response consumer interface. One facet wished the Chat reply to look like search outcomes, with solutions positioned on relevancy to the question. Others wished a brand new “interactive, chat-based method of looking.”

Ultimately, Microsoft mixed Search and Chat in a single interface that enables customers to change between Search and Chat mode by clicking on a component of the web page or by scrolling up and down.
