Does FLUX have Custom Instructions?

FLUX does not support Custom Instructions. Set persistent, global rules for how the AI should behave or respond across all chats (e.g., always output Python code, or never use emojis). FLUX is Black Forest Labs’ image (and, in FLUX 3, video) model family. No global instruction profile. Fine-tunes/LoRAs are weights, not a system prompt.
