What is Flux 2?

October 2026 update: Flux 3 is Black Forest Labs' newest PRO flagship — native 4K, prompt-to-edit, and up to 10 reference images included in the output price. Flux 3 Klein (20 October 2026) is the fast, affordable Flux 3 — from 0.75 credits at 1K, with up to 4 reference images. Flux 2 remains available. Use the Flux 2 Klein models if you do not have PRO, or if you want a cheaper all-rounder on a free account. Prefer Flux 3 Klein if you have PRO. Flux 2 still charges extra credits for each start image; full Flux 3 includes reference images in the output price; Flux 3 Klein adds a capped surcharge for references.

Flux 2 (by Black Forest Labs) is a versatile, high-quality image model available on NightCafe in several variants, so you can trade off quality, speed and cost:

• Flux 2 Pro — improved image quality, great at photorealism.
• Flux 2 Dev — a strong all-rounder at reasonable cost.
• Flux 2 Flex — better at typography and designs.
• Flux 2 Max — grounded generation tied to real-world context, and maximum quality for complex or production workflows.
• Flux 2 Klein family — the fastest, smaller variants (free-account friendly).

What it’s good at

• Prompt-to-edit and multi-image fusion — supported across the Flux 2 variants.
• Grounded generation — Flux 2 Max can tie results to real-world and real-time information.

Good to know

Flux 2 models charge credits for each start image you include, on top of the base cost.
