A developer shared the journey of designing a chip from scratch just a few months ago. The team reverse-engineered Groq's LPU (Language Processing Unit) architecture and successfully used it to run Andrej Karpathy's MicroGPT. The post details the learning process and technical insights gained from reinventing the inference architecture to achieve ultra-fast speeds without prior chip design experience.
