Copilot is not OpenAI

[District5524]

The pipeline Microsoft is using for Copilot products hides actually what models they are using, and you have no influence over it. Sometimes they use smaller models, but I have no clear source from Microsoft saying this ...

It is OpenAI weights under the hood, unless something changed recently?

At least Bing Chat was GPT-4-base with Microsoft's own fine-tuning.

And there's been a number of iterations of 4o. So it could be a really old, pruned one if upgraded from gpt-4.

Copilot is OpenAI in branding since day 1.
