A developer compiled a working RISC-V CPU into the weights of an AI model
A developer compiled a working 32 bit RISC-V CPU into the weights of Qwen 3.5 4B. The model uses its own Gated DeltaNet layers as RAM and runs exact arithmetic, C and MicroPython inside its forward pass, with no external tool. Long integer math jumps from 48.6% to 100%.
