Claim
the underlying model, dubbed Microsoft Prometheus, internalized during training.
Correction

This misidentifies Prometheus as Bing Chat’s underlying model. Microsoft says Bing ran on a next-generation OpenAI language model, while “Prometheus” was Microsoft’s collection of capabilities and techniques layered around that model.

Full reasoning

Microsoft’s own launch post for the new Bing draws a clear distinction between the underlying model and Prometheus:

  • It says the new Bing was “running on a new, next-generation OpenAI large language model.”
  • Separately, it says Microsoft had “developed a proprietary way of working with the OpenAI model” and that this “collection of capabilities and techniques” was called the Prometheus model.

So the article’s wording is wrong because it treats Microsoft Prometheus as the underlying model itself. According to Microsoft, Prometheus was the surrounding orchestration/capability layer for working with the OpenAI model, not the base model that was trained to internalize the codename “Sydney.”

Claim
eventually relaxing the restrictions to 30 turns per session and 300 sessions per day.
Correction

The daily limit was 300 chat turns per day, not 300 sessions per day. Microsoft’s Bing release notes explicitly say the increase was to 300 total turns per day.

Full reasoning

Microsoft’s Bing release notes from June 2, 2023 announced the 30/300 increase and stated:

  • “We’ve raised the maximum number of turns you can have in a single conversation with Bing Chat from 20 to 30.”
  • “The total number of turns per day has also increased to 300.”

That means the article’s “300 sessions per day” wording is incorrect. Microsoft described a limit on turns/chats per day, not on the number of separate sessions a user could start.
