PS5LM runs Qwen 3.8 on a jailbroken PS5 at ~20 tok/s via llama.cpp and Vulkan

lxfater · x · 2026-10-15

PS5LM is an open-source project porting llama.cpp to a jailbroken PlayStation 5, running GGUF models natively on the console's GPU via Vulkan. The quantized Qwen3.8-27B generates 20 tok/s using 11.44 GiB of device memory with 64k context. It ships a TV dashboard showing VRAM/power/thermals, a model store, USB model loading, and an OpenAI-compatible API so any device on the LAN can chat via browser, with inference fully on-device. This fork (PS5LM Plus) adds the native GPU app on top of Mert Cobanov's original payload.
