Summary
Flux 2 Klein is Black Forest Labs' distilled, low-latency image model accessible through RunComfy's CLI. It ships with documented prompting patterns that materially improve output: subject-first grammar, step-count strategies (4–8 for concepting, ~25 for polish), and multi-reference brand styling workflows. The 4B variant gives sub-second feedback for live iteration sessions, while 9B trades speed for detail. The skill includes routing logic to help you pick between Klein, Flux 2 Pro, and competing models based on whether you need iteration speed or maximum resolution. The prompting guide is unusually specific,actual working patterns like declarative composition order and conditional edit syntax,not generic advice.
