fal-train — Claude Code skill: train LoRA models on fal.ai
A skill that trains LoRA models on fal.ai so image generation matches a brand, a character or a style.
npx skills add nexu-io/open-design --skill fal-train -a claude-codeWhat fal-train does
fal-train is an OpenDesign catalogue skill that points your agent at LoRA training on fal.ai. It fits projects where generated images have to look like your brand, a specific character or a repeating style rather than generic output.
The entry ships a SKILL.md in the nexu-io/open-design repo and links upstream to fal-ai-community/skills. The actual workflow, with its scripts and assets, lives in that upstream bundle, so you install it into your agent's skills directory as well. The agent picks fal-train up during planning and invokes it by name or through triggers such as “fal train”, “train lora” or “brand lora”.
Training on fal.ai needs an account and an API key there; without one the training step goes nowhere. If you only need prompt-to-image generation, there is nothing to train and this skill adds nothing.
What it helps with
- train a LoRA on a brand's visual style
- keep one character consistent across generated images
- reproduce a single style across an image set
- wire model training into an agent inside the IDE
Example prompts for the agent
- Train a LoRA on fal.ai from these reference images for our brand style
- Run fal-train and build a dataset for this character
- Set up custom model training for image generation

Questions about fal-train
How do I install fal-train in Claude Code?
Run npx skills add nexu-io/open-design --skill fal-train -a claude-code. The skill lands at ~/.claude/skills/fal-train/SKILL.md.
What does fal-train do?
It trains LoRA models on fal.ai so image generation follows a given brand, character or style.
What do I need before running fal-train?
A fal.ai API key and the upstream fal-ai-community/skills bundle installed in your agent's skills directory, since the catalogue entry only carries SKILL.md.
