PS5LM Plus Runs Llama.cpp Models On A Jailbroken PS5 GPU
Running as a home screen app instead of a jailbreak payload lifts the usable memory ceiling from about 6GiB to 12GiB and opens the GPU through Vulkan, the difference between a demo and a model that can be left running.

A GitHub project called PS5LM Plus runs GGUF language models on a jailbroken PlayStation 5 and serves chat from a PC or phone on the same network. Developer abhi245y built it on PS5LM, Mert Cobanov's llama.cpp port. In the developer's measurements, Qwen3.8-27B at UD-IQ2_XXS generated 20.7 tokens per second, and Llama 3.2 3B Instruct Q4_K_M loaded from USB reached 124 tokens per second.
Launching from the home screen rather than as a payload is the whole point of the build. The developer says a payload is capped at roughly 6GiB with no GPU access, while the app form uses 12GiB and the GPU through llama.cpp's Vulkan support and a ported driver.
Model files load from internal storage, an added M.2 SSD, or a USB drive, and a search function pulls them from Hugging Face. The selection screen shows each model's size and whether it fits in available memory, and context and cache limits adjust themselves. A dashboard on a connected TV reports token speed, GPU and CPU load, temperature, and memory use.
