AI Text to Image

Node icon
AI

Generates images from text prompts using AI, with four model tiers from fast drafts to maximum quality.

AI Text to Image creates images from a text description. Four model tiers balance speed and quality: FLUX Fast (quick iterations), FLUX.2 Pro (professional output), Nano Banana 2 (best prompt understanding, web search), and FLUX.2 Max (highest fidelity).

The output is a standard image that wires into any other node: feed it through Palette Remap, add effects, composite it, or export directly. AI is just another node in the pipeline.

Notes

Tier-dependent visibility: Fast shows Output Width/Height (with size presets), Steps, Guidance Scale, Negative Prompt. Quality/Premium show Output Width/Height (with size presets, 16px-aligned), Safety Tolerance. Advanced shows Nb2 * params. Size presets available for all per-MP tiers.

Usage Tips

Section titled “Usage Tips”
  • Start with Fast tier for prompt iteration, then switch to Quality/Advanced for final output.
  • Use a negative prompt to exclude unwanted elements.
  • Wire the output into Remove BG to get a clean cutout on transparent background.
  • Set a specific seed to reproduce a result you like, then tweak the prompt while keeping the same composition.
