Qwenputer: a 32-bit RISC-V CPU compiled into Qwen3.5's weights

Someone built "Qwenputer": a 32-bit RISC-V CPU compiled directly into Qwen3.5's model weights, executing instructions inside the network, with the Gated DeltaNet state serving as the CPU's RAM (registers and memory mapped across layers). The author suggests this could have implications for tool calling and computer use — if the model can natively run programs in its weights, the tool-use paradigm could shift. An absurd but technically serious demo.
