Hello hello everyone, this is Alex, typing these words from beautiful Seattle (really, it only rained once while I was here!) where I'm attending Microsoft biggest developer conference BUILD. This week we saw OpenAI get in the news from multiple angles, none of them positive and Microsoft clapped back at Google from last week with tons of new AI product announcements (CoPilot vs Gemini) and a few new PCs with NPU (Neural Processing Chips) that run alongside CPU/GPU combo we're familiar with. Those NPUs allow for local AI to run on these devices, making them AI native devices! While I'm here I also had the pleasure to participate in the original AI tinkerers thanks to my friend Joe Heitzberg who operates and runs the aitinkerer.org (of which we are a local branch in Denver) and it was amazing to see tons of folks who listen to ThursdAI + read the newsletter and talk about Weave and evaluations with all of them! (Btw, one the left is Vik from Moondream, which we covered multiple times). I Ok let's get to the news: TL;DR of all topics covered: * Open Source LLMs * HuggingFace commits 10M in ZeroGPU (X)* Microsoft open sources Phi-3 mini, Phi-3 small (7B) Medium (14B) and vision models w/ 128K context (Blog, Demo)* Mistral 7B 0.3 - Base + Instruct (HF)* LMSys created a "hard prompts" category (X)* Cohere for AI releases Aya 23 - 3 models, 101 languages, (X)* Big CO LLMs + APIs* Microsoft Build recap - New AI native PCs, Recall functionality, Copilot everywhere * Will post a dedicated episode to this on Sunday* OpenAI pauses GPT-4o Sky voice because Scarlet Johansson complained* Microsoft AI PCs - Copilot+ PCs (Blog)* Anthropic - Scaling Monosemanticity paper - about mapping the features of an LLM (X, Paper)* Vision & Video* OpenBNB - MiniCPM-Llama3-V 2.5 (X, HuggingFace)* Voice & Audio* OpenAI pauses Sky voice due to ScarJo hiring legal counsel* Tools & Hardware* Humane is looking to sell (blog)Open Source LLMs Microsoft open sources Phi-3 mini, Phi-3 small (7B) Medium (14B) and vision models w/ 128K context (Blog, Demo)Just in time for Build, Microsoft has open sourced the rest of the Phi family of models, specifically the small (7B) and the Medium (14B) models on top of the mini one we just knew as Phi-3. All the models have a small context version (4K and 8K) and a large that goes up to 128K (tho they recommend using the small if you don't need that whole context) and all can run on device super quick. Those models have MIT license, so use them as you will, and are giving an incredible performance comparatively to their size on benchmarks. Phi-3 mini, received an interesting split in the vibes, it was really good for reasoning tasks, but not very creative in it's writing, so some folks dismissed it, but it's hard to dismiss these new releases, especially when the benchmarks are that great! LMsys just updated their arena to include a hard prompts category (X) which select for complex, specific and knowledge based prompts and scores the models on those. Phi-3 mini actually gets a big boost in ELO ranking when filtered on hard prompts and beats GPT-3.5 ? Can't wait to see how the small and medium versions perform on the arena.Mistral gives us function calling in Mistral 0.3 update (HF)Just in time for the Mistral hackathon in Paris, Mistral has released an update to the 7B model (and likely will update the MoE 8x7B and 8x22B Mixtrals) with function calling and a new vocab. This is awesome all around because function calling is important for agenting capabilities, and it's about time all companies have it, and apparently the way Mistral has it built in matches the Cohere Command R way and is already supported in Ollama, using raw mode. Big CO LLMs + APIsOpen AI is not having a good week - Sky voice has paused, Employees complainOpenAI is in hot waters this week, starting with pausing the Sky voice (arguably the best most natural sounding voice out of the ones that launched) due to complains for Scarlett Johansson about this voi
