Comparison
FLUX 3 Klein vs Krea 2
Krea 2 is Krea AI's in-house text-to-image model, published on May 12, 2026, with open weights. FLUX 3 Klein is Black Forest Labs' small open-weights image model, released on October 15, 2026, and it generates and edits images with one model. That second point matters most: Krea 2 does not edit images, so the two are not interchangeable. Below are the published specifications side by side, and four images generated here with FLUX 3 Klein, each with its prompt.
This box opens the generator with FLUX 3 Klein, the only model this site runs. Write a prompt, then compare it with the four outputs below.
Published specifications
Every row has a public source, and figures no source states are left out. Read the task row first: the two models do not cover the same work.
| FLUX 3 Klein | Krea 2 | |
|---|---|---|
| Released | October 15, 2026 | May 12, 2026 |
| Parameters (image generator) | 5.6B | 12.9B |
| Task scope | Text-to-image, single-reference editing and multi-reference generation in one model | Text-to-image only; no image editing |
| Open weights | Yes — FLUX Kommunity License: non-commercial use, plus commercial output for users under US$5M annual revenue | Yes — Krea AI Community License |
| Variants | Distilled (16 steps, no guidance) for generation and editing; undistilled base (50 steps, guidance 3.5) for fine-tuning and research | Turbo (8-step distilled) for fast inference; RAW (undistilled base) for fine-tuning and LoRA training |

The Krea 2 parameter count is Black Forest Labs' figure for the image generator, encoders excluded. Speed, VRAM, Elo and user counts are left out: only vendor self-assessments exist.
When to reach for which
Neither wins here; the two take different jobs. Match the work in front of you to the model, not the model to the news.
Editing a photo you already have
Only one of the two does this. Krea 2 has no edit path — Krea's editing model is Krea 3 — so when a picture exists and has to change, the job belongs to FLUX 3 Klein, with the instruction written as a description of the finished picture.
Generating from a written idea
Krea 2 is built around aesthetic direction, style references and moodboards; FLUX 3 Klein takes a full scene caption and up to ten reference images, and can place elements with boxes on a 0–1000 grid.
Holding a subject consistent across shots
Reference images do this work. FLUX 3 Klein accepts up to ten, one way to keep a product, a face or a material steady from frame to frame.
Iterating fast on many directions
Krea's own launch page puts Krea 2 at 15 seconds or less per image, and the checkpoint this site runs is the distilled 16-step FLUX 3 Klein. Treat both numbers as vendor claims.
Self-hosting and fine-tuning
Both ship open weights under different licences: train LoRAs on Krea 2 RAW or on the undistilled FLUX 3 Klein base checkpoint, and read the licence before either goes into a product.
Four FLUX 3 Klein outputs from here
Every image below was generated here with FLUX 3 Klein (distilled, 1K), with the prompt under it. No Krea 2 output appears on this page, because this site does not run it.
Product photo
The bowl stays whole and centred, and the oak grain, the linen napkin and the three walnuts all survive.
Studio product photograph of a matte terracotta ceramic bowl on a pale oak table, soft morning window light from the left, a folded linen napkin and three walnuts beside it, clean warm-white background, 50mm lens, realistic glaze texture.
Bakery interior
A wide interior with one barista at the lever machine, two customers by the tall window and trays of sourdough, with legible lettering on the wall sign.
Wide interior shot of a busy artisan bakery at opening time, wooden counter with trays of sourdough, a barista pulling a lever espresso machine, two customers waiting by the window, warm morning light through tall windows, dust in the air, architectural photography, straight verticals.
Book cover with text
The three-line title, the two cream rules and the small-caps author line all hold, and both names are spelled correctly.
Minimal book cover with the title "SALT AND PINE" in a tall serif typeface centred on a deep forest-green field, a thin cream rule above and below the title, the author name "I. HALVARD" in small caps at the bottom, flat printed look, no other elements.
Isometric illustration
One isometric angle, a tram across the front, warm amber windows on a teal ground, and no stray letters in the picture.
Flat isometric illustration of a small city block at night, warm windows, a tram crossing the front, teal and amber palette, clean geometric shapes, soft grain, no text, no letters.
What this site supports today
This site runs FLUX 3 Klein and nothing else — no Krea 2 tab, no model switcher. Here is what the online generator does.
One model for generating and editing
Text-to-image and editing are the same FLUX 3 Klein model here, running the distilled checkpoint.
Up to three reference images
Attach one to three images and name them as <ref_image_1> to <ref_image_3>; the released checkpoint takes up to ten.
1K and 2K output
Fifteen aspect ratios from 1:1 to 21:9, saved as JPEG, PNG or WebP.
Credits per generation
Text-to-image: 2 credits at 1K, 8 at 2K. Editing: 4, 5 or 6 at 1K with one, two or three references, and 13, 15 or 17 at 2K.
Not supported here
Ten reference images, bounding boxes, 4K output, LoRA training and weight downloads are not supported here.
Ten languages
Everything here and the help pages are available in ten languages.
FLUX 3 Klein and Krea 2
Is Krea 2 a drop-in replacement for FLUX 3 Klein?
No. Krea 2 generates images from text and does not edit them; Krea's editing model is Krea 3. FLUX 3 Klein does both with one checkpoint, so where an edit is the job there is no choice to make.
Can Krea 2 edit a photo?
Krea's own release pages present it as a text-to-image model, and Black Forest Labs keeps Krea 2 out of its image-editing comparison for the same reason. Edits happen with Krea 3 there, or with FLUX 3 Klein here.
How do the two treat reference images?
FLUX 3 Klein takes up to ten and lets the prompt name them and place elements with boxes on a 0–1000 grid; Krea 2's release material is built around style references and moodboards, and its style-reference workflow uses one to two images.
