According to @MRRydon, a groundbreaking development has unlocked full neural network training capabilities, including backpropagation, directly on Apple's Neural Engine (ANE) without relying on CoreML, Metal, or GPUs. This innovation enables ultra-efficient AI model training on M4 chips, achieving 6.6 TFLOPS per watt and significantly reducing costs and environmental impact. The Zero-Human Company is already leveraging this to advance autonomous AI systems, marking a transformative shift in AI training from cloud-based GPUs to local Mac devices.
