Qwenputer: a fully functioning, deterministic RISC-V CPU inside Qwen3.5
Summary
Qwenputer describes embedding a fully functional, deterministic RV32IM RISC-V CPU inside the Qwen3.5 model weights, using Gated DeltaNet layers as RAM. The CPU runs entirely within the model's forward passes, supports C and MicroPython, and includes an in-model filesystem; benchmarks show high arithmetic accuracy with no external runtimes. The work is experimental, resource-intensive, and demonstrates novel in-model computation and governance considerations for AI systems.
