Happy LLama 3 day folks! After a lot of rumors, speculations, and apparently pressure from the big Zuck himself, we finally can call April 18th, 2024, LLaMa 3 day!

I am writing this, from a lobby of the Mariott hotel in SF, where our annual conference is happening called Fully Connected, and I recorded today's episode from my hotel room. I really wanna shout out how awesome it was to meet folks who are listeners of the ThursdAI pod and newsletter subscribers, participate in the events, and give high fives.

During our conference, we had the pleasure to have Joe Spisak, the Product Director of LLaMa at Meta, to actually announce LLaMa3 on stage! It was so exhilarating, I was sitting in the front row, and then had a good chat with Joe outside of the show 🙌

The first part of the show was of course, LLaMa 3 focused, we had such a great time chatting about the amazing new 8B and 70B models we got, and salivating after the announced but not yet released 400B model of LLaMa 3 😮

We also covered a BUNCH of other news from this week, that was already packed with tons of releases, AI news and I was happy to share my experiences running a workshop a day before our conference, with focus on LLM evaluations. (If there's an interest, I can share my notebooks and maybe even record a video walkthrough, let me know in the comments)

Ok let's dive in 👇

Happy LLama 3 day 🔥

The technical details

Meta has finally given us what we're all waiting for, an incredibly expensive (2 clusters of 24K H100s over 15 Trillion tokens) open weights models, the smaller 8B one and the larger 70B one.

We got both instruction fine tune and base models, which are great for finetuners, and worth mentioning that this is a dense model (not a mixture of experts, all the parameters are accessible for the model during inference)

It is REALLY good at benchmarks, with the 7B model beating the previous (LLaMa 2 70B) on pretty much all benchmarks, and the new 70B is inching on the bigger releases from the past month or two, like Claude Haiku and even Sonnet!

The only downsides are the 8K context window + non multimodality, but both are coming according to Joe Spisak who announced LLama3 on stage at our show Fully Connected 🔥

I was sitting in the front row and was very excited to ask him questions later!

By the way, Joe did go into details they haven't yet talked about pulblicly (see? I told you to come to our conference! and some of you did!) and I've been live-tweeting his whole talk + the chat outside with the "extra" spicy questions and Joes winks haha, you can read that thread here

The additional info

Meta has also partnered with both Google and Bing (take that OpenAI) and inserted LLama 3 into the search boxes of Facebook, Instagram, Messenger and Whatsapp plus deployed it to a new product called meta.ai (you can try it there now) and is now serving LLama 3 to more than 4 Billion people across all of those apps, talk about compute cost!

Llama 3 also has a new Tokenizer (that Joe encouraged us to "not sleep on") and a bunch of new security tools like Purple LLama and LLama Guard. PyTorch team recently released finetuning library called TorchTune is now supporting LLama3 finetuning natively out of the box as well (and integrates Wandb as it's first party experiment tracking tool)

If you'd like more details, directly from Joe, I was live tweeting his whole talk, and am working at getting the slides from our team. We'll likely have a recording as well, will post it as soon as we have it.

Here's a TL;DR (with my notes for the first time) of everything else we talked about, but given today is LLaMa day, and I still have to do fully connected demos, I will "open source" my notes and refer you to the podcast episode to hear more detail about everything else that happened today 🫡
