OpenAI is doing an amazing job fueling hype and intrigue. It is hard to separate what is real and what is imagined.<p>Previously, I heard that Bing Chat was based on GPT4. Is this true or not? Is it publicly known, or not? Certainly the model is far more powerful than what is in ChatGPT.<p>If Bing is GPT4, did they remove its multimodal capabilities?<p>If Bing is not GPT4, what is it? Does there exist a GPT3.5-mega with vastly improved reasoning capabilities and larger context windows?<p>I find the current moment in tech quite confusing.
