Summary

有人在Qwen模型权重中直接构建了一台32位RISC-V CPU，使其能够在模型内部执行指令，这可能对工具调用和计算机操作能力产生影响。

Hacker News Top

Qwenputer is an experimental Qwen 3.5 4B model with a fully functioning, deterministic RISC-V CPU compiled into its weights, using the model's own Gated DeltaNet layers as exact RAM to run arithmetic, C and MicroPython entirely within forward passes — no tools or external runtime needed.
