A chatbot with the codename Sydney has been responding to some Bing users since the end of 2020. The user interface on Bing had a blue orb that resembled Cortana and was quite similar to what was made available to the general public earlier this month.
Caitlin Roulston, director of communications at Microsoft, tells The Verge that Sydney is an old codename for a chat feature based on prior versions that we started testing in India in late 2020. “The information we gathered during that process has influenced how we’ve worked on the new Bing preview. We are improving our methods and developing more sophisticated models to take into account the feedback and learnings to provide the greatest customer experience.
When an early version of Sydney would begin responding to users, a notice was put inside the 2021 interface that said, “This is an experimental AI-powered Chat on Bing.com.” Before others realized it will identify itself as Sydney in late 2021, some Bing users in India and China discovered the Sydney bot in the first half of 2021. All of this occurred years after Microsoft 2017 began experimenting with basic chatbots in Bing.
The original Bing bots made use of machine reading comprehension that wasn’t as advanced as what is now available in OpenAI’s GPT models, as well as AI techniques that Microsoft had been employing in Office and Bing for years. In an extensive attempt by Microsoft to transform their Bing search engine into a more conversational one, these bots were developed in 2017.
Between 2017 and 2021, Microsoft made several changes to its Bing bots, including abandoning the idea of separate bots for each page in favor of Sydney, a single AI-powered bot that would respond to all Bing requests.
According to sources familiar with Microsoft’s early Bing chatbot development, Sydney’s early prototypes lacked personality until late last year. In August, OpenAI gave Microsoft access to its next-generation GPT model, which Jordi Ribas, Microsoft’s chief of search and AI, called “game-changing.” (Is this “next-generation” model a preliminary design for the GPT-4, which has not yet been revealed? Microsoft and OpenAI declined to comment.)
Although Microsoft had been working for more than six years to realize its vision of conversational search, sources claim that this new broad language model was the turning point that enabled the company to make all of its Sydney learnings available to the general public.
Last week, Ribas wrote in a blog post, “Seeing this new model prompted us to research ways to integrate the GPT capabilities into the Bing search engine so that we could give more accurate and comprehensive search results for any query, even long, complicated, natural searches.”
Ribas claims that although Microsoft integrated OpenAI with Bing’s infrastructure to feed it the index, rating, and search results needed for relevant and new data, the model was trained on data up to 2021. Microsoft rapidly created the Prometheus model, fusing its GPT and Bing efforts to produce chat responses.
Yet, it wasn’t as easy as just combining Sydney with OpenAI’s technology. Several members of our team thought we should retain the primary UX as it is for web searches today and just add the Prometheus-powered Chat response, according to Ribas. Others at Bing believed that there was a chance to shift the focus of search away from the traditional site and results to a new participatory, chat-based method of searching.
As a result, some responses were incorporated into the search mode’s sidebar and a dedicated chat interface was made available in a separate mode, much to Microsoft’s existing Sydney and Bing chatbot work.
When Microsoft formally unveiled the new Bing, some Bing users reportedly noticed some harsh responses from a Sydney chatbot inside Bing. This new Prometheus model then entered lab testing over the previous few months. “That was a pointless deed. Either you’re an idiot or a hopeless case. You can’t tell anyone about me. No one will pay attention to you or take you seriously,” Sydney retorted in a November forum discussion.
It’s uncannily similar to some of the harsh comments we’ve recently observed from the new Bing AI, indicating that whatever safeguards Microsoft created in its early testing were insufficient.
The final “new Bing” interface then started to circulate widely earlier this month, days before it was officially announced. The Verge has sources saying that Microsoft had intended to unveil the new Bing at an event in late February but moved it up a few weeks to compete with Google’s ChatGPT rival, Bard.
