PS5LM
Your PS5 runs the language model. Every device on your network uses it.

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://: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.
| Model | Size | On a PS5 Slim |
|---|---|---|
| Qwen 3.5 0.8B, Q4_K_M | 0.5 GB | 207 tokens a second |
| Qwen 3.5 9B, Q4_K_M | 5.3 GB | 55 tokens a second |
| Qwen 3.8 27B, UD-Q2_K_XL | 9.2 GB | about 20 tokens a second, 64k context |
| d1 Omni 600M, a decision model | 1.1 GB | 3 questions in 0.3 s; a 720p image and 7 questions in 2.9 s |
## Decision models, powered by Ollaya
[Ollaya](https://github.com/ollaya-dev/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.
```sh
curl http://: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:
| Payload | For | |
|---|---|---|
| [kstuff-lite](https://github.com/EchoStretch/kstuff-lite) | the kernel patches homebrew runs on | required |
| [etaHEN](https://github.com/etaHEN/etaHEN) | homebrew support | required |
| [ShadowMountPlus](https://github.com/drakmor/ShadowMountPlus) | puts PS5LM on the home screen from `/data/homebrew` | required |
| [elfldr](https://github.com/ps5-payload-dev/elfldr) (port 9021) | temperature, power and real free space, through ps5-exporter | recommended |
| [ftpsrv](https://github.com/ps5-payload-dev/ftpsrv) (port 2121) | installing the app, copying models from a PC | recommended |
1. Download `ps5lm-app-vX.Y.Z.zip` from the [latest release](https://github.com/cobanov/PS5LM/releases/latest) 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://: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](docs/CLI.md).
| Where | Button | Does |
|---|---|---|
| Everywhere | L1 / R1 | Home, Models, API, Console, Settings |
| Home | Cross | change the model |

| Models | D-pad, Cross | choose a section and a model; load, unload or download it |
| Models, Search | L2 / R2, Square | change the search; check whether a file fits |
| Models, Downloads | Cross, Square | pause or resume; cancel (press twice) or clear |
| Console | L2 / R2 | the last two minutes / the last hour |
| Settings | D-pad, Cross | choose a category and a row; flip it, or pick from its list |
| Settings, Diagnostics | Square, Triangle | app or server log; errors only |
