Upscale images and video 2x to 4K/8K on the user's GPU through Guaardvark (Real-ESRGAN, HAT-L, SwinIR, two-pass). Use when the user asks to enlarge, sharpen, restore, or upscale a picture, a batch of pictures, or a video.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Upscaling with Guaardvark
Read `setup` first; needs the `upscaling` plugin (`POST /api/plugins/upscaling/start`).
`B=${GUAARDVARK_URL:-http://localhost:5000}`. Models: `GET $B/api/upscaling/models` (default `HAT-L_SRx4`);
install one with `POST $B/api/upscaling/models/download {"model": "<id>"}` only after the user says so.
## One image (synchronous, seconds)
```bash
curl -s -X POST $B/api/upscaling/upscale/image \
-F file=@/abs/path/in.png -F model=HAT-L_SRx4 -F scale=4 -F sharpen=0.2 -F denoise_strength=0.1
```
Returns the finished file (`output_path`, served under `GET $B/api/upscaling/output/image/<filename>`).
Form options: `model`, `scale`, `sharpen`, `denoise_strength`.
## Many images (queued)
```bash
curl -s -X POST $B/api/upscaling/upscale/images -F files=@a.png -F files=@b.png -F model=HAT-L_SRx4 -F scale=2
```
Returns a job id; poll `GET $B/api/upscaling/jobs/<job_id>`; `GET $B/api/upscaling/jobs` lists all.
## Video (queued, frame by frame)
```bash
curl -s -X POST $B/api/upscaling/upscale/video -H 'Content-Type: application/json' -d '{
"input_path": "/abs/path/clip.mp4", "model": "realesrgan-x2", "scale": 2, "two_pass": false, "suffix": "_4k"
}'
```

How to install
mdr add guaardvark/guaardvark/upscale@sha256:bc8fdb71190b8221The line at the top of this page pins the label git:20260911.973d1bc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
