Jailbroken PS5 runs Qwen3.8-27B locally at 20 tokens/s, developer reports

PS5LM Plus, a community-made app for jailbroken consoles, can run quantized AI models on a PS5’s GPU. Its developer reports Qwen3.8-27B generating at about 20 tokens per second; [Techjunkie Aman’s X post](https://x.com/Techjunkie_Aman/status/2110307764446892271) highlights the demo, and the [PS5LM Plus repository](https://github.com/abhi245y/PS5LM) publishes the app and its test details. PS5LM Plus is a fork of [Mert Cobanov’s original PS5LM project](https://github.com/cobanov/PS5LM), which ports llama.cpp to jailbroken PS5 hardware. The Plus fork adds a native app that uses the console’s GPU through Vulkan and makes a chat interface and API available to other devices on the same network. That turns a jailbroken PS5 into a small local model host: prompts can stay on the home network instead of being sent to a cloud AI service, while models can be downloaded separately from Hugging Face. The headline speed depends on the model setup. The developer lists Qwen3.8-27B UD-Q2_K_XL at 20.3 tokens/s with a 32K context, and a smaller 6.8 GiB quantized version at 20.7 tokens/s with a 64K context. The same README reports 61 tokens/s for Gemma 4 E4B and 124 for Llama 3.2 3B. These are the developer’s own results, not independent benchmark tests. The figures also describe generated output, not model quality or how quickly a long prompt is processed. [Hardware Upgrade’s report](https://www.hwupgrade.it/news/web/ps5-e-ia-generativa-qwen-27b-gira-sulla-gpu-con-ps5lm-plus_160566.html) likewise notes that the results depend on quantization and test conditions. This is not an AI feature for an ordinary PS5: the app requires a jailbreak and other homebrew components. The project’s published measurements come from one PS5 Slim (CFI-2015) on firmware 13.60, according to its [console notes](https://github.com/abhi245y/PS5LM/blob/main/docs/CONSOLE.md), so they do not establish compatibility across every console model or firmware. If you’re checking your own setup, start with [our PS5 Scene guide to supported firmware and setup](https://www.mushimu.com/post/8726). The next useful evidence will be repeatable tests on additional hardware and clearer compatibility notes. ~ps5scene ~ai
