this week was absolutely bonkers. For starters, for the first time ever, we got an Open Weights model (Command R+) to jump over GPT-4 in human rankings on LMsys, this is huge!Then on Tuesday, it seems that all the companies just wanted to one up one another, first Gemini 1.5 released with updates, made it available in 180 countries, added audio mode + tons of API improvements and system prompts, then less than an hour later, OpenAI has given us a "majorly improved" GPT-4 Turbo version (2024-04-09) that is now back to being the BEST LLM IN THE WORLD and to cap that day off, Mistral did the thing again, the thing being, dropping a torrent link in a tweet with no explanations.What was in that torrent is a Mixtral 8x22B MoE (which we started calling Bixtral) which comes with an Apache2 license and seems to be VERY good!We also saw the first finetune from HuggingFace/KAIST folks less than 48 hours later (the authors of said finetune actually came on the show ? )Fully Connected is a week from today!

Though it's hard because this model requires a lot of compute to finetune, and not only GPUs, Matt Sh
