That makes no sense because the largest Qwen models are not even open weight so I’m not sure how that’s any different.

Right, which isn't what we're discussing, since I mentioned "across multiple providers" in every comment about this topic.

Those closed weight models aren't available like we're discussing. They're only available from the vendor that created them.

The largest qwen model is similar so I’m not sure what point you’re trying to make. The only ones available are the open weight ones which are the smaller variants and nowhere near within 20% of the closed frontier models.

The largest open models are within 20%; they're likely within 10%. Go actually try them and stop making outdated assumptions. You don't need to invest a lot of money either, just pick your favorite vendor, and send out a few prompts.
