SUPIR Repo Skill

Use this skill when a task is about SUPIR, SupPixel/SUPIR photo restoration, photo-realistic image enhancement, image upscaling, caption-assisted diffusion restoration, SUPIR checkpoints, SUPIR/sgm/llava imports, or the repo's batch and Gradio-style workflows.

SUPIR is a CUDA-first research preview. Do not treat it as a CPU package. Its public workflows load large SDXL, SUPIR, CLIP, and LLaVA checkpoints and can be expensive. Prefer preflight and dry-run checks before model loading.

First checks

1. Read references/checkpoints-and-environment.md before running anything that loads a model. It lists required checkpoint variables, config files, backend assumptions, and optional UI/face dependencies.
2. Use scripts/check_supir_assets.py to inspect a config and validate candidate checkpoint paths without loading weights.
3. If imports or CUDA fail, read references/troubleshooting.md before changing package versions.
4. For YAML variants and shared parameters, read references/configuration-reference.md.

Operating model

• SUPIR normally uses one CUDA device for restoration and a second CUDA device for LLaVA captioning when two GPUs are visible. With one GPU both model families share the same device. With no CUDA device the repo scripts abort.
• Q and F select different SUPIR restoration checkpoints. Q is the default high-quality/general checkpoint; F favors fidelity under light degradation.
• LLaVA is optional for several workflows. When captioning is unavailable, use manual prompts or --no_llava/local-prompt routes.
• The UI/demo stack is optional unless the user wants browser interaction. The core API/batch environment can be valid without Gradio installed.
• Respect the upstream non-commercial-use declaration when planning usage or deployment.

Self-contained assets in this skill

• scripts/check_supir_assets.py: safe config and checkpoint validator.
• sub-skills/python-api-and-config/scripts/supir_api_probe.py: safe import/signature probe.
• sub-skills/batch-restoration/scripts/supir_batch_restore.py: adapted batch-restoration wrapper with --dry-run support.
• sub-skills/interactive-demos/scripts/supir_demo_preflight.py: safe launcher preflight for standard, tiled, and face demo modes.

Avoid these mistakes

• Do not load checkpoints just to inspect CLI flags or signatures; use the bundled probes first.
• Do not assume a CPU import check verifies SUPIR restoration. CUDA is required for truthful end-to-end validation.
• Do not paste private absolute checkpoint paths into prompts, reports, or generated configs. Use environment variables or user-provided public paths.
• Do not route generic Stable Diffusion image generation or unrelated LLaVA serving tasks here unless SUPIR source APIs, configs, or workflows are named.
