Llama 3 just came out so they couldn't have used it, and Claude Haiku is the smallest cheapest closed source model out there from what I've seen.

Github is likely using a GPT-4 class model which is two (massive) steps up in capabilities in Anthropic's offerings alone

Yeah I just mentioned Llama to point out that the open weight models have been really catching up.

Microsoft is almost certainly using GPT-4 given their relationship with ClosedAI, but I would definitely not put GPT-4 (nor Turbo) "two massive steps up" from Claude 3 Opus. I have access to both through Kagi, and I have found myself favoring the responses of Claude to the point where I almost never use GPT(TM) anymore.

You're misreading in multiple ways, maybe in a rush to dunk on "Closed AI".

Github Copilot is not the same as Copilot Chat which uses GPT-4, there still some uncertainty on if Copilot completions use GPT-4 as outsiders know it (and iirc they've specifically said it doesn't at some point)

I also said Haiku is two massive steps behind Anthropic's offerings... which are Sonnet and Opus.

Anthropic isn't any more open than OpenAI, and I personally don't attribute any sort of virtue to any major corporation, so I'll take what works best

I... don't think I misread you? Maybe you didn't mean what you wrote, but what you said was:

> Github is likely using a GPT-4 class model which is two (massive) steps up in capabilities in Anthropic's offerings alone

Comparing GPT-4 to Anthropics offerings, which, as you say, includes Sonnet and Opus.

> Anthropic isn't any more open than OpenAI, [...] so I'll take what works best

I understand that, and same here. I don't prefer Claude for any reason other than the quality of its output. I just think OpenAIs name is goofy with how they actually behave, so I prefer the more accurate derivative of their name :)

Regarding what model Copilot Completions is using - point taken, I have no comment on that. My original comment in this thread was only meant to point out that open weight models are getting a lot better. Not saying they're using them.

I used "in Anthropic's capabilities" intentionally: it's two steps up in what they can do from Claude Haiku
