GoKawiilDeveloper embeds RISC-V CPU into Qwen 3.5 4B LLM's weights, runs DOOM on it
AI engineer Divyansh Agrawal built 'Qwenputer,' a modified version of Qwen 3.5 4B that has a 32-bit RISC-V CPU compiled directly into 11 additional transformer layers placed ahead of the model's own weights. The CPU uses the model's Gated DeltaNet state as RAM and can execute C and MicroPython code and arithmetic operations without calling any external tools, and has been shown running the game Doom, albeit slowly.
