Episode Details

Hey everyone, this is Alex and can you believe that we're almost done with Q1 2024? March 2024 was kind of crazy of course, so I'm of course excited to see what April brings (besides Weights & Biases conference in SF called Fully Connected, which I encourage you to attend and say Hi to me and the team!)

This week we have tons of exciting stuff on the leaderboards, say hello to the new best AI in the world Opus (+ some other surprises), in the open source we had new MoEs (one from Mosaic/Databricks folks, which tops the open source game, one from AI21 called Jamba that shows that a transformers alternative/hybrid can actually scale) and tiny MoE from Alibaba, as well as an incredible Emotion TTS from Hume.

I also had the pleasure to finally sit down with friend of the pod Tanishq Abraham and Paul Scotti from MedArc and chatted about MindEye 2, how they teach AI to read minds using diffusion models 🤯🧠👁️
