Microsoft's head of search, Mikhail Parakhin, wrote on Twitter that Bing Chat uses 100% GPT-4 in Creative and Precision modes. Balanced mode uses a combination of language models, including GPT-4. In addition to the OpenAI models, Microsoft uses the Prometheus model, a "collection of skills and techniques," and its own Turing language models in Bing. The Turing models also controls Bing's search results.
