Generate Image with FLUX.2 Klein
Use this skill to generate images locally using the FLUX.2 Klein 4B model.
Workflow
-
Craft a rich prompt using the FLUX formula:
[Subject] + [Action/Pose] + [Style/Medium] + [Setting] + [Lighting] + [Camera]- Preserve all specific details the user mentioned
- Add lighting if not specified: golden hour, soft diffused, dramatic rim, studio three-point
- Add camera if not specified: "shot on Hasselblad 85mm f/2.8, shallow depth of field"
- Use hex codes for specific colors (e.g. "#1A2B3C deep navy")
- Describe what you WANT — negative prompts don't work with this model
-
Run the script:
source ~/venvs/flux/bin/activate && python3.11 ~/Documents/gen-images/claude-cli/flux_klein.py --prompt "<your prompt here>"
-
Parse the output path from the last line of stdout (
Saved to <path>) -
Auto-open in Preview:
open <path>
- Report the path to the user.
Prompt Formula Example
User: "a fisherman at sunset"

A weathered fisherman in his 70s, navy cable-knit sweater, standing at the helm of a wooden boat. Golden hour light from the left, dramatic rim lighting. Shot on Hasselblad 85mm f/2.8, shallow depth of field, Kodak Portra 400 color science.
