Llama.cpp on a jailbroken PS5: run any GGUF model natively on the console
A jailbroken PlayStation 5 allows users to run any GGUF model natively on the console, powered by llama.cpp. The new PS5LM application enables users to access decision models like d1, Clef, and OpenJev directly on the PS5's GPU. These models provide typed decisions with calibrated probabilities, similar to OpenJev, in a fraction of a second.
PS5LM can serve the models to other devices on the same network, such as laptops and smartphones, without requiring a PC, cloud service, or account. It supports a range of models, including Qwen 3.5 9B, which can answer requests from a laptop connected to a PS5 Slim. With firmware versions 7.00 to 13.60, PS5LM can run on jailbroken PS5 consoles, provided the required payloads are loaded.
PS5LM operates independently of Sony and its SDK files, and the application is licensed under GPL-3.0-or-later, with the llama.cpp component under MIT and Manrope.
