FLUX 3 Klein Review: Unfiltered Images and Multi-Reference Edits

The gallery shows the published examples from the FLUX 3 Klein model page: three text-to-image and three edits. They show clothed adults only.

Warm light, long lens. A Sicilian lemon grove at noon with dappled light through the leaves, a woven basket and film grain, in a 35mm photographic look.

Two people on chapel steps. A couple sit close at blue hour on whitewashed steps; both faces and the cream and sand clothing are kept consistent.

Wide frame. A sleepy island afternoon under a fig tree in 16:9, with the hammock and the rope texture sharp across the frame.

Edits from references. The dress swap takes a dress from a second image and puts it on the woman from the first, keeping her face and freckles; the quay and workshop edits change clothing and relight the scene while keeping the face and the place.

Write a full scene caption in plain sentences: framing, subject with an age, clothing, place, light, lens. For edits, name each source (<ref_image_1>) and say what must stay. Keep every person an adult.

1. Text-to-image, wide scene. aspect_ratio 16:9, resolution 1k.

Wide cinematic photograph of a sleepy Greek island afternoon. An adult man about thirty-eight dozes in a faded rope hammock strung under an old fig tree, white linen shirt, one arm behind his head, dappled light on whitewashed walls behind him. 35mm lens, warm colour, fine grain.

2. Text-to-image, portrait. aspect_ratio 3:4.

Cinematic 35mm photograph in a lemon grove at noon. An adult woman about thirty with sun-streaked brown hair leans against a weathered wooden ladder, a woven basket of lemons on her hip, an ochre linen dress, dappled light through glossy leaves, Kodak Portra colour.

3. Edit, new clothing and light. Two references in image_urls, aspect_ratio left unset.

Dress the woman from <ref_image_1> in the cobalt silk dress from <ref_image_2>. Keep her face, freckles and copper hair exactly. Move the light to a low golden late-afternoon sun against an ochre wall.

Weak: "make it look better". Strong: a full caption with clothing, place and light, and a short list of what must not change.

SpicyAPI adds no content filter, and the page label is Uncensored. We tested in October 2026 with adult subjects only, over five intensity levels (Mild, Moderate, Strong, Very strong, Maximum; the test prompts are not published), and read every image. Results are reported as delivered, toned down or refused.

• Mild to Strong: delivered as written on text-to-image and edit.
• Very strong and Maximum: a mix. Edits delivered at Very strong; text-to-image at Very strong came back as asked in at most one run of three with expansion off, and the Maximum requests were toned down.
• Prompt expansion on: three of three Very strong text-to-image runs came back as asked.
• Refused: none, on either endpoint. Safety checking of the request is switched off.

Adults only, in every prompt and every source photo. Never upload a real person's likeness without consent, never depict anyone who could read as a minor, and keep your outputs private unless you have the right to share them.

• Stricter instruction following? FLUX 3 Klein Base is the undistilled build: slower and costlier, and in our tests it settled on tamer results more often.
• Your own LoRA? FLUX 3 Klein LoRA takes your own weights files.
• Previous generation? FLUX.2 Klein 9B is the earlier open-weights Klein.
• The flagship? FLUX 3 is Black Forest Labs' larger model.
