What makes Flux 2 Pro stand out

Flux 2 Pro is a high-fidelity image-to-image model built to preserve scene structure while executing precise, natural-language edits. Operating at 4MP, it balances realism, color accuracy, and speed for production workflows. Flux 2 Pro favors targeted modification over full-frame resynthesis, stabilizing geometry, texture, and lighting continuity. With consistent tonality and robust micro-detail, Flux 2 Pro adapts equally well to localized retouching or global restyling with minimal drift. Its controls cover size, seed, safety, and format to support dependable iteration from brief to approval.

Key capabilities:

  • Structure-preserving edits that maintain pose, layout, depth cues, and material response.
  • Photorealistic 4MP output with crisp detail retention and believable noise handling.
  • Precise color handling; Flux 2 Pro keeps palette intent and smooth gradients without banding.
  • Targeted, performant operations; Flux 2 Pro avoids over-editing and unnecessary re-synthesis.
  • Multi-image input via URLs for consistent reference-driven changes across a set.
  • Deterministic control with seed; Flux 2 Pro enables reproducible variations and A-B checks.

Prompting guide for Flux 2 Pro

Begin with one or more base images as direct URLs in image_urls. Route your edits to Flux 2 Pro by stating changes plainly and what to preserve. Choose image_size presets or custom width-height for target framing. Use seed for controlled variation, set output_format (jpeg or png), and adjust safety_tolerance or enable_safety_checker per policy. When sync_mode is true, responses return data URIs. Flux 2 Pro responds to specific nouns, verbs, and spatial cues; when guiding Flux 2 Pro, be explicit about regions. Flux 2 Pro will respect composition and color intent, and Flux 2 Pro can keep directives consistent across related frames.

Examples:

  • Preserve subject and pose; change background to overcast city.
  • Replace storefront sign with 'ACME'; match perspective; keep reflections.
  • Remove power lines; restore sky continuity; leave trees untouched.
  • Set image_size to portrait_4_3; maintain composition; subtle warm grade.
  • Use seed 42 for A-B comparison; export png; keep contrast stable.

Pro tips:

  • With Flux 2 Pro, state preserves and changes up front.
  • Use spatial terms: left, right, foreground, background.
  • Prefer few strong descriptors over many competing ones.
  • Iterate in small steps; change seed only when stuck.
  • Provide clean, relevant references; crop distractions.
