FLUX Image Models
Five FLUX models for every need - from sub-second prototyping to publication-quality high-fidelity generation and precise context-aware editing. Black Forest Labs' open-weight architecture powers the most versatile model family in AI image generation.
Generate with FLUX → All ModelsFLUX Model Lineup
Five distinct models spanning speed, quality, and editing capability.
FLUX.2 Pro
BFL's most advanced model. State-of-the-art prompt adherence with high-fidelity results - best when creative accuracy matters more than speed or cost.
Best forDemanding briefs, client work, campaign assets
StrengthsPrompt fidelity, fine detail, lighting accuracy
TypeProprietary API
FLUX.1 Kontext Max
Enhanced Kontext built for maximum quality. Keeps characters and objects perfectly consistent across a series of edits - no drift between iterations.
Best forCharacter consistency, multi-step editing workflows
StrengthsContext retention, consistency, high resolution
TypeProprietary API
FLUX.1 Kontext
Controllable image generation with deep context awareness. Each edit builds naturally on the last - ideal for iterative workflows where you refine in passes.
Best forIterative editing, controlled generation
StrengthsPrecision, control, context retention
TypeProprietary API
FLUX Dev
Flexible open-weight model for detailed, realistic images. Popular with developers who fine-tune on custom datasets or integrate FLUX into their own pipelines.
Best forDeveloper workflows, custom fine-tuning, realism
StrengthsOpen weights, fine-tuning, realistic output
TypeOpen weights
FLUX Schnell
Fastest
Speed-optimised model that generates quality images in seconds. The most cost-efficient FLUX model - perfect for rapid idea testing and early-stage prototyping.
Best forQuick drafts, A/B testing, prototyping concepts
StrengthsSpeed, cost, volume generation
TypeOpen weights
Why the FLUX Family Stands Out
No other model family covers this range - from instant prototyping to precision multi-step editing.
Speed Range
FLUX Schnell is the fastest model on the platform. FLUX.2 Pro is the highest quality. One family covers both extremes with consistent output style.
Context-Aware Editing
Kontext models understand what you changed in previous steps - no drift between edits, no restarting from scratch on complex multi-pass workflows.
Open Weights
FLUX Dev and Schnell are open-weight models - fine-tune on your own dataset, integrate into custom pipelines, or self-host for complete control.

FAQ - FLUX Models
Which FLUX model should I start with?
Use FLUX Schnell for drafts and iteration - it's fastest and cheapest. Once you have a direction, switch to FLUX.2 Pro for final high-quality output, or Kontext for editing-focused workflows.
What makes Kontext different from regular FLUX?
Kontext models retain context between edits - they understand what you changed in previous steps. This keeps characters and objects consistent across multiple rounds of editing.
Is FLUX open source?
FLUX Dev and FLUX Schnell are open-weight models available for research and fine-tuning. FLUX.2 Pro and Kontext are proprietary API-only models from Black Forest Labs.
How does FLUX compare to GPT Image or Recraft?
FLUX has the widest range of models covering speed to quality. GPT Image 2 is stronger on photorealism. Recraft leads on text-in-image accuracy. FLUX Schnell is the fastest model across any provider.
Can I fine-tune FLUX on my own images?
Yes - FLUX Dev and Schnell are open-weight models designed for fine-tuning. You can train on your own dataset to create a custom style or subject-specific model. This is a key advantage over closed API-only models.
