🤖 Tesla demonstrates Optimus Gen 2

Tesla has unveiled the Optimus Gen 2 humanoid robot, showcasing improved humanlike dexterity and mobility. The robot features 11 degrees of freedom in its hands with tactile sensors in each finger, a 2-DoF neck, in-house-designed actuators and sensors, and integrated electronics. The enhancements include a 30% increase in walking speed, force/torque sensing, articulated toe sections in its feet, and a 10 kg weight reduction for improved energy efficiency, cost, and safety.

The company plans to initially deploy the robot in its automotive and battery factories. However, amidst the positive news, Tesla is also recalling over 2 million vehicles due to concerns surrounding its Autopilot system. The National Highway Traffic Safety Administration (NHTSA) is investigating safety issues related to Autopilot, and critics argue that Tesla didn't adequately communicate the risks.

Despite the recall, Tesla CEO Elon Musk has released an impressive video of the Gen 2 Optimus robot, emphasizing its capabilities and addressing skepticism. Musk believes the Optimus business could eventually surpass the value of Tesla's car business and full self-driving technology.

📼 Andrej Karpathy’s Baby Llama Runs on Samsung Galaxy Watch 4

Andrej Karpathy, from OpenAI, developed Baby Llama as a weekend project to demonstrate the possibility of running the Llama 2 model on edge devices. The project, inspired by Georgi Gerganov's llama.cpp, involves training the Llama 2 model using PyTorch and then saving the weights in a binary file. Karpathy created a compact C file ('run.c') for loading and running the model with single-precision calculations, ensuring a low-memory footprint and independence from external libraries.

The model runs efficiently even on a single M1 laptop without GPUs, with performance enhancements achieved through various compilation flags for code optimization. A Twitter user successfully demonstrated Baby Llama running on a Samsung Galaxy Watch 4.

Karpathy's repository provides the pre-trained model and code, allowing anyone to experiment with Baby Llama on their devices. It's important to note that this project is experimental and not meant for production use, aiming to showcase the viability of running advanced models on low-powered devices with C, a language typically not associated with machine learning due to its GPU incompatibility.

⛓ 3 trends for 2024: edge intelligence, RISC-V, & chiplets

This article discusses three major technology trends expected to shape 2024:

➡️ Edge Intelligence Enhancement: The article highlights advancements in deploying large language models (LLMs) on devices with limited memory, particularly focusing on a research paper by Apple. This paper introduces techniques for efficient LLMs operation on such devices, indicating a broader trend of increased machine learning and inference capabilities at the edge of networks.

➡️ RISC-V Architecture Adoption: The formation of Quintauris, a company backed by major tech players, is set to accelerate the commercialization of RISC-V hardware globally. This development suggests a growing interest in RISC-V architecture, especially in automotive, mobile, and IoT applications. The industry is moving towards heterogeneous computing architectures, where RISC-V plays a crucial role in various functions.

➡️ Rise of Chiplets: Chiplets are emerging as a solution to the high demands of machine learning-intensive products. The trend is compared to the evolution of the intellectual property business two decades ago. Startups like Zero ASIC are democratizing chip-making with platforms for chiplet-based design and emulation. The increasing use of chiplets will rely on standardization efforts like the UCIe specification.
