Llama.cpp on a jailbroken PS5: run any GGUF model natively on the console

Your PS5 runs the language model. Every device on your network uses it.

New: decision models, powered by Ollaya. PS5LM now runs Jev-like decision models (d1, Clef, OpenJev and more) on the GPU and answers the same /v1/systemone API as Ollaya: typed decisions with calibrated probabilities, in a fraction of a second.

PS5LM is for anyone with a jailbroken PS5 who wants a private model server at home. It loads a GGUF model onto the console's GPU and serves it to your laptop, your phone and your coding tools. It needs no PC while it runs, no cloud and no account.

A model server under your TV

• It runs on the GPU. llama.cpp's Vulkan backend on the console's RDNA 2 GPU, with 11.4 GB of the shared memory for the model and its context. Every architecture and quantization llama.cpp knows comes along.
• It answers your network. OpenAI's /v1/chat/completions, Anthropic's /v1/messages (Claude Code works against it) and a chat page in any browser. Point a client at http://<console>:8081 and use any model name: the loaded one answers.
• It decides, too. Load a decision model and the console answers TypeSafe's /v1/systemone: choice, score and yes-or-no questions about text and images, the API Ollaya serves on a PC.
• It shows its work. Every request streams across the TV as a chat: which device asked, what it asked, and the reply as it is written. Square sends a demo and Triangle opens a keyboard, so the console can be tried from the couch.
• It watches the console. A Console page charts temperature, power, GPU and CPU load over the last two minutes or the last hour, beside a table of every reading.
• It picks what fits. The planner reads each GGUF and gives it the longest context and best cache that fit the memory free. A Suggested list holds models measured on the console, and the app downloads from Hugging Face by itself, to internal storage, the M.2 drive or a USB drive.
• It reads images. Models with an image projector (Gemma 4, MiniCPM-V, d1) take pictures in chat and in decisions.

Decision models, powered by Ollaya

Ollaya runs open decision models on a PC the way Ollama runs language models. PS5LM brings the same idea to the console: a decision model reads a state and answers typed questions in one forward pass, with no text generated.

curl http://<console>:8081/v1/systemone -H 'Content-Type: application/json' -d '{
  "state": "I was charged twice this month. Refund me or I cancel.",
  "questions": {
    "intent": {"type": "choice", "instructions": "What does the customer want?",
               "criteria": {"refund": null, "information": null, "cancel": null}},
    "angry":  {"type": "noul", "instructions": "Is the customer angry?"}
  }
}'

The Suggested list has d1 Omni 600M, d1 3B and Clef Flash. Any GGUF that carries llama.cpp's decision metadata loads the same way, and the app labels it a decision model.

Try it

You need a PS5 on firmware 7.00 to 13.60, jailbroken, with these payloads loaded:

1. Download ps5lm-app-vX.Y.Z.zip from the latest release and unzip it.
2. Copy the PPSA99575 folder to /data/homebrew over FTP. ShadowMountPlus adds PS5LM to the home screen.
3. Open PS5LM, go to Models > Suggested and get a model. Or copy a .gguf to /data/PS5LM/models, or to PS5LM/models on a USB drive.
4. Load it. Once Home says Ready, open http://<console>:8081 in a browser, or point your OpenAI or Anthropic client at it.

To update, copy the new folder over the old one. Settings, models and downloads stay in /data/PS5LM. Using it from coding tools (opencode, Codex, Claude Code) is in docs/CLI.md.
