FLUX.2 — Black Forest Labs, Nov 2025 — 4MP native, 10 reference images, 32K token prompts

FLUX.2 Prompt Generator

The FLUX.2 prompt generator gives you 20 free, copy-paste prompts for Black Forest Labs' FLUX.2 image model. Native 4MP output, up to 10 reference images, 32,000 token prompts — Pro, Max, and Dev variants covered.

What is the FLUX.2 Prompt Generator?

The FLUX.2 prompt generator on this page provides 20 free, professionally written prompts for FLUX.2 — the second-generation image model from Black Forest Labs, released November 25, 2025. FLUX.2 is the successor to FLUX.1 and introduces headline upgrades: native 4MP resolution output, up to 10 reference images per generation, 32,000 token text input, and frontier-grade photorealism with accurate lighting and physics simulation.

FLUX.2 comes in four variants for different use cases: FLUX.2 [pro] for commercial API use, FLUX.2 [max] for maximum resolution and detail, FLUX.2 [dev] as an open-weight model for fine-tuning and research, and FLUX.2 [klein] for sub-second high-throughput inference. The prompts below are optimised for FLUX.2 [pro] and [max].

Where FLUX.2 distinguishes itself from competitors is in controllability. With 10 reference images and 32K tokens, a developer or professional user can specify colour palettes by HEX code, provide character reference photos, supply style examples, and write prompts with the length and precision of a full creative brief. Every prompt below demonstrates this approach.

How to Write FLUX.2 Prompts

Black Forest Labs recommends a front-loaded structure with the most important element first:

[Main subject] → [Key action] → [Critical style] → [Essential context] → [Secondary details + HEX colours + variant]

FLUX.2 Key Capabilities:

  • Native 4MP resolution output (4× FLUX.1)
  • Up to 10 reference images per generation
  • 32,000 token text input — full creative briefs
  • HEX colour code precision — passed directly
  • Frontier photorealism with physics accuracy
  • Open-weight Dev model for fine-tuning / LoRA

Best Practices:

  • Put the subject first — FLUX.2 weights early tokens heavily
  • Use positive phrasing only — no negation
  • Name the photography or art style explicitly
  • Pass HEX codes for precise colour control
  • State the variant: 'FLUX.2 Pro' or 'FLUX.2 Max'
  • Use reference images for character and style consistency

High-end cookware editorial style. 4MP FLUX.2 Pro.

4. Landscape — Patagonia Dawn

Nature

A wide-angle dawn photograph in Patagonia: the Torres del Paine granite towers lit in orange and pink alpenglow, a glassy lake in the foreground perfectly reflecting the towers. No wind — the reflection is flawless. A single guanaco grazes in the left foreground, establishing scale. Shot at f/11, deep depth of field, everything sharp from foreground to towers. Landscape photography. FLUX.2 Max, 4MP.

5. Fashion Editorial — Minimal Studio

Editorial

A minimalist fashion editorial: a male model, early 30s, stands against a seamless white studio wall wearing a structured olive-green overcoat, dark wool trousers, clean white shirt open at the collar. His posture is relaxed, arms at his sides. The lighting is entirely flat and even from two large softboxes — no shadows. Shot with a medium-format equivalent lens. Clean, still, editorial menswear aesthetic. FLUX.2 Pro.

6. Interior — Tokyo Ramen Shop at Night

Atmosphere

Interior of a small Tokyo ramen shop at 11 PM: eight counter seats, a long cypress wood counter, the chef visible behind through a service window. Red paper lanterns hang from the low ceiling. Two customers eating, heads slightly bowed. Steam rises from bowls. Shot from the entrance looking in — the warm amber interior against the dark street outside. Documentary street photography aesthetic, slight grain. FLUX.2 Pro.

7. Typography — Book Cover Design

Typography

A literary novel book cover, portrait orientation. Background: deep forest green linen texture. Centred title in large classical serif typeface, cream: 'THE QUIET SEASON'. Below, in smaller serif: 'A Novel by E. L. Marchetti'. A single botanical illustration — a pencil sketch of a bare winter branch — sits between the title and author name. Tasteful, prize-contending literary fiction design. 4MP FLUX.2 Pro.

8. Macro Photography — Morning Dew

Nature

An extreme macro shot of a spider's web in the early morning: hundreds of perfect water droplets suspended on the silk strands, each droplet refracting the garden behind it.

BBC Earth quality. FLUX.2 Max.

9. Street Photography — Paris Rain

Street

A rainy Paris evening on a narrow Marais street: cobblestones reflecting the warm glow of a brasserie window. A woman in a black trench coat and red scarf walks away from camera under a small umbrella. Shot at 1/60s — the umbrella sharp, the cobblestones gleaming, a few pedestrians blurred in the background. Captured as if on Kodak Portra 400 film. Grain prominent, colours slightly muted. FLUX.2 Pro.

10. Character Concept — Space Marine

Character

Full-body character concept art of a space marine officer, female, mid-40s, standing at ease in a pressurised corridor of a military ship. Her armour is utilitarian — matte grey titanium composite, wear marks at the joints, a unit patch on the left shoulder. She holds a helmet under one arm. Her expression is tired but authoritative. Concept art quality, detailed, suitable for a game or film production pitch. FLUX.2 Pro, 4MP.

11. Food Photography — Sourdough Bread

Commercial

A halved sourdough loaf on a dark linen cloth. The interior crumb is open and irregular — large air pockets in the centre, smaller tight crumb near the crust. The crust is dark, deeply scored. A bread knife rests beside it. Shot from a 45-degree angle at loaf height. One softbox from camera-left, warm tungsten tone. Artisan bakery editorial style. No garnish, no props beyond the cloth and knife. FLUX.2 Pro.

12. Sci-Fi Environment — Abandoned Station

Sci-Fi

A derelict space station interior: a wide circular observation room, floor-to-ceiling windows looking onto a gas giant in amber and rust. Emergency lighting only — red strip lights along the floor, one flickering overhead panel. Dust particles float in the light shafts. Vegetation has begun growing through a cracked floor panel. No people. The composition centres on the window and the planet behind it. Concept art / cinematic realism hybrid. FLUX.2 Max.

13. Brand Identity — Coffee Packaging

Typography

Flat lay of a premium coffee brand's packaging: a matte black 250g bag with a single-origin label.

Shot at three-quarters angle, the lamp light providing key light from camera-right. Cinematic period film quality. FLUX.2 Pro.

20. Abstract — Paint Textures

Abstract

A macro photograph of an abstract oil painting in progress: thick impasto strokes in deep cobalt blue and raw umber, palette knife tracks visible through the paint surface. The paint edges catch light from a single raking spotlight, creating strong shadows across the texture relief. Shot from directly above, the canvas fills the frame. The paint is wet — slightly reflective. Art documentation photography, 4MP FLUX.2 Max.

FLUX.2 vs. Other AI Image Models (May 2026)

How FLUX.2 compares to the current leading image generation models:

Model Reference Images Open Weight Best For
FLUX.2 [pro/max] (BFL) ★ Up to 10 per generation Yes (Dev + Klein) Developer control, fine-tuning, character consistency
GPT Image 2 (OpenAI) Limited No Product photography, UI mockups, Arena #1
Nano Banana Pro (Google) Up to 14 No Text in images, 4K editorial, Google ecosystem
MAI Image 2 (Microsoft) No No Portrait photorealism, natural lighting
MidJourney v7 Limited No Artistic, stylized, conceptual art

★ FLUX.2 leads on controllability (10 reference images, 32K token input) and is the only major model with an open-weight variant (Dev) available for fine-tuning. GPT Image 2 leads the overall Arena leaderboard.

FLUX.2 Prompting Tips

Do This:

  • Put the subject before the style in every prompt
  • Name a specific photography or art tradition
  • Use HEX codes for precise brand colour matching
  • Provide reference images for style or character consistency
  • State the variant (Pro, Max, Dev) to set quality expectations
  • Use the full 32K token budget for complex creative briefs

Avoid This:

  • Negative phrasing — describe what you want, not what you don't
  • Putting style before subject — front-load the subject
  • Vague colour descriptions — use HEX codes instead
  • Keyword stacking without descriptive context
  • Mixing incompatible aesthetic traditions in one prompt
  • Leaving the photography style unspecified for realism outputs

Frequently Asked Questions — FLUX.2

What is the FLUX.2 prompt generator?

The FLUX.2 prompt generator on this page provides 20 free, copy-paste prompts for FLUX.2 — Black Forest Labs' next-generation image model family, released November 2025. FLUX.2 includes four variants: FLUX.2 [pro] (highest quality, photorealistic), FLUX.2 [max] (maximum resolution and detail), FLUX.2 [dev] (open-weight, fine-tunable), and FLUX.2 [klein] (fastest inference). The prompts here are designed for FLUX.2 [pro] and [max] unless otherwise noted.

What is FLUX.2 and who made it?

FLUX.2 is the second major generation of the FLUX image model family, developed by Black Forest Labs (BFL) — the team founded by the original Stable Diffusion researchers. Released November 25, 2025, FLUX.2 introduced significant upgrades over FLUX.1: native 4MP output resolution (4 megapixels, compared to FLUX.1's 1MP ceiling), up to 10 reference images per generation request (enabling complex style transfers and character consistency), 32,000 text token input (far longer and more detailed prompts), and frontier-grade photorealism with accurate real-world lighting and physics. The FLUX.2 [klein] sub-family (released January 2026) delivers sub-second inference on capable hardware.

How do I write an effective FLUX.2 prompt?

FLUX.2 responds to structured, front-loaded prompts. The recommended structure is: Main subject → Key action → Critical style → Essential context → Secondary details. Crucially, put your most important element first — FLUX.2, like most diffusion models, weights early tokens more heavily. Use positive phrasing only (describe what you want, not what you don't want). For photorealistic outputs, name a specific photography style ('architectural documentary', 'editorial menswear', 'wildlife photography'). For artistic outputs, reference a specific aesthetic tradition. You can pass HEX colour codes directly and FLUX.2 will respect them. Specify 'FLUX.2 Pro' or 'FLUX.2 Max' in the prompt to signal the quality tier you are targeting.

What is the difference between FLUX.2 Pro, Max, Dev, and Klein?

FLUX.2 has four variants with different use cases: FLUX.2 [pro] is the standard commercial model — highest quality for API and platform use, balancing output quality with generation speed. FLUX.2 [max] is the top-tier variant for maximum resolution, fine detail, and photographic accuracy — slower and higher cost per generation. FLUX.2 [dev] is the open-weight model available on Hugging Face for fine-tuning, LoRA training, and research use — not for commercial API production but excellent for building custom style models. FLUX.2 [klein] is the speed-optimized family (sub-second inference) for high-throughput production pipelines where generation speed matters more than maximum quality.

Where can I access FLUX.2?

FLUX.2 is available through several channels: the Black Forest Labs API directly at bfl.ai (pay-per-generation), Replicate (API and web interface), fal.ai (developer API), Cloudflare Workers AI (FLUX.2 [dev]), ComfyUI and Diffusers (for FLUX.2 [dev] local inference), and through platforms like Adobe Firefly Enterprise, Canva, and others that have licensed the model. FLUX.2 [dev] weights are freely available on Hugging Face for non-commercial use. For consumer use, the BFL API is the most direct route to FLUX.2 [pro] and [max] quality.

How does FLUX.2 compare to GPT Image 2, Nano Banana Pro, and MAI Image 2?

As of May 2026: GPT Image 2 leads the Arena leaderboard overall and is strongest for product photography and UI mockups. Nano Banana Pro leads on in-image text rendering and native 4K output. MAI Image 2 leads on photorealistic portraiture and natural lighting. FLUX.2 [pro/max] competes across all categories but leads specifically on two: (1) controllability — with 10 reference images, 32K token context, and HEX colour precision, FLUX.2 gives developers and professional users the most direct control over output; (2) fine-tuning — FLUX.2 [dev] is the most capable open-weight base model for building custom style or character-consistent pipelines. For developers building products rather than end users generating one-off images, FLUX.2 is often the first choice.
