Can GPT-4 teach a robot hand to do pen-spinning tricks better than you do?

Eureka bridges the gap between high-level reasoning (coding) and low-level motor control. It is a “hybrid-gradient architecture”: a black box, inference-only LLM instructs a white box, learnable neural network. The outer loop runs GPT-4 to refine the reward function (gradient-free), while the inner loop runs reinforcement learning to train a robot controller (gradient-based).

RL community should be in awe and shocked by the Eureka paper🫨. The idea here is that you feed the source code of the environment to GPT-4 and ask it to write code for the reward function itself! Then you evaluate this reward function in simulation and provide your evaluation results back to GPT-4 so it can make improvements to the reward function!! You do this over and over and RL eventually ends up achieving superhuman results in lots of different challenges, all without human intervention!!!

How to blend images in Dalle3:
Two steps:
1) uniquely identify the images
2) Ask to blend the images

CorticalLabs - grow brain on wires

A difference in company philosophy:
@neuralink: put wires on brain.
@CorticalLabs: grow brain on wires.
Cortical Labs just completely changed my dreams and nightmares.
Here it is in Hon Weng’s hotel room. He is showing this off tomorrow at a brain conference in San… twitter.com/i/web/status/1…
