Haven't seen a jump this large since I don't even know, years? Too bad they are not releasing it anytime soon (there is no need as they are still currently the leader).

not much of a jump 94.5% / 91.3%

  Error with 91.3% = 8.7%
  Error with 94.5% = 5.5%

  Error reduction = 8.7% - 5.5% = 3.2%

I've long maintained that the real indicator that AGI is imminent is that public availability stops being a thing. If you truly believed you had a superhuman, godlike mind in your thrall, renting it out for $20/month would be the last thing you would choose to do with it.

It's not a matter of knowledge, it's a matter of resources. It takes billions of dollars of hardware to train a SOTA LLM and it's increasing all the time. You cannot possibly hope to compete as an independent or small startup.

Eventually these super expensive SXM data center GPUs will cost pennies on the dollar, and we’ll be able to snatch up H200s for our homelabs. Give it a decade. Also eventually these WEIGHTS will leak. You can’t have the world’s most valuable data that can just be copied to a hard drive stay in the bottle forever, even if it’s worth a billion dollars. Somehow, some way, that genie’s going to get out, be it by some spi…

Open models still haven't caught up to ChatGPT's initial release in 2022. Now that the training data is so contaminated (internet is now mostly LLM slop), they may never. Also, OpenAI's only real moat used to be the quality of their training data from scraping the pre-GPT-3.5 Internet, but it looks like even they've scratched that too.

Er, what? We've had open models that can outperform ChatGPT 3.5 for several years now, and they can run entirely on your phone these days. There is no metric by which 3.5 has not been exceeded.
