PS5LM runs local LLMs on a jailbroken PS5
Confirmed
The takeaway
An open-source project, PS5LM (GitHub user cobanov, GPL-3.0), ports llama.cpp to the GPU of a PlayStation 5 jailbroken on firmware 7.00–13.60 and serves GGUF models on the home network through OpenAI- and Anthropic-compatible APIs.

Key facts
- Requirements: PS5 on firmware 7.00–13.60, jailbroken, with the kstuff-lite, etaHEN and ShadowMountPlus payloads; model and context share about 11.4 GB of console memory
- Listed speeds (PS5 Slim): Qwen 3.5 0.8B Q4_K_M 207 tok/s; Qwen 3.5 9B Q4_K_M 55 tok/s; Qwen 3.8 27B UD-Q2_K_XL about 20 tok/s with 64k context
- Endpoints: OpenAI-compatible and Anthropic-compatible APIs, plus a /v1/systemone endpoint for small decision models

What happened
After the PS5 jailbreak for firmware up to 13.60, a hobbyist ported llama.cpp so the console’s GPU can run quantised open-weight models and act as a local inference server for coding tools that speak the OpenAI or Anthropic API.
Why it matters
It shows how far local inference has spread: a games console with about 16 GB of shared memory can serve a 27B model at usable speed.
