Inference

Use this sub-skill when the user wants to generate a video with Helios.

Typical triggers

• "generate a video"
• "run text-to-video"
• "turn this image into a video"
• "animate this clip"
• "use the distilled checkpoint"
• "try the low-VRAM or multi-GPU path"
• "launch the demo"

What this sub-skill covers

• Text-to-video, image-to-video, and video-to-video generation.
• Base, Mid, and Distilled checkpoint selection.
• Prompt-only and prompt-plus-image/video generation.
• Multi-GPU context parallelism.
• Low-VRAM offload and common runtime toggles.
• The demo-style workflow, with the caveat that the local UI module is not a lazy import and can do expensive work at startup.

What it does not own

• Dataset metadata preparation belongs in data-preparation.
• Stage configuration, training launches, and checkpoint merging belong in training.
• Benchmark/evaluation metrics are not a primary route in this generated skill.

• references/workflows.md for end-to-end generation choices and run flow.
• references/cli-reference.md for the bundled inference helper and the key runtime flags it exposes.
• references/troubleshooting.md for GPU/backend, import, and input-shape failures.
• scripts/run_helios_inference.py for the bundled inference helper.

Working rule

Prefer the bundled helper and the compatibility check before relying on a raw source checkout or guessing at the backend.
