Yifan Zhang's RLT technical report carries decoder state across every token, looping 96 blocks per token with unbounded temporal depth. In standard decoder-only LLMs, nothing computed at token t's last layer feeds token t+1's first layer.

A hobbyist connected a simulated fly brain to the PCSX2 emulator with a virtual PS controller and dopamine readout, using Mr. Mosquito as the first visual cue test. The builder says the project has no real-world value and is a way to learn about spiking neural networks, with a quasi-universal trainer in progress.
