Embedding CPUs in LLM Weights: Determinism vs Flexibility?

Developers embedded a RISC-V CPU into Qwen3.5 weights, using GDN layers as RAM. This 'Qwenputer' runs C code and arithmetic internally without external tools, with >97% accuracy. Compared to standard tool use, this doubles model size and slows speed but ensures internal control.
