Flux 2 Klein 9B Base: lock this still before you buy motion (2cr)

Flux 2 Klein 9B Base is the stills row. Animate after approval. Do not generate the pack inside the video model.

Flux (Black Forest Labs' image key), 2 credits, text-to-image. Description: "Text-to-image generation with FLUX.2 [klein] 9B Base from Black Forest Labs. Enhanced realism, crisper text generation, and native editing capabilities." requires_image is false. No listed max resolution. Aspects: 1:1, 4:3, 3:4, 16:9, 9:16. Up to 4 reference slots. audio does not apply. This is a still you can read — including lettering — at 2 credits. It is not Flux 3 Text to Video.

2 credits is the stills bill. Spend it on a pause frame.

Klein 9B Base is the cheap Flux.2 stills SKU: enhanced realism, crisper text, native editing capabilities. Use it to lock a poster, a pack hero, a label. Then stop. Reviewers pause on frames. If the words on the product are mush, animating the mush does not make a pack. Generate here until the type holds. 2 credits a pop is the point of a base weight.

Aspects include 9:16 and 16:9, unlike Wan 2.6's 1:1 / 4:3 / 3:2 list. Pick the shipping ratio on this row. Do not "fix it in the video model." Flux 3 video will sample a new identity while it does motion. That identity will not be the lettering you just approved.

Text to image is the door. Flux's roster is the image family. Video from the same company sits on Black Forest Labs. Best Flux model ranks the image side. This page is Klein 9B Base at 2 credits.

Native editing is still not motion

The description includes native editing capabilities. That means you can retouch a still on this family without jumping to a random other brand. It does not mean this SKU is a video editor. It does not list durations. It does not list audio. "Edit the still" is allowed. "Animate the pack inside the video model because Klein can also edit" is the name-swap.

If you already have a locked still and the job is a delta, use the edit as an edit: one change, keep the rest. If you do not have a locked still, generate. Max reference 4 is a stills budget — style or subject pins — not a storyboard of motion.

Flux's stills register wants natural language: composition, colour palette, mood, and photographic camera language when you want photoreal. Write that into the still. Do not write a dolly into a model that cannot move.

Approve, then buy motion on a video row

Sequence:

1. Generate or edit stills on Flux 2 Klein 9B Base. 2 credits. Ratio from the list.
2. Kill anything whose text or face would embarrass a pause.
3. Animate keepers on an image-to-video row — the image-to-video tool, or a Flux.3 video SKU on the Black Forest Labs roster if you want to stay in-house.

Skipping the pause is how a 9B-base still that would have been cheap to re-roll becomes an expensive clip you cannot thumbnail. The video model is not a better Flux.2. It is a different content type.

FAQ

Does Klein 9B Base generate video?

No. Content type is image. 2 credits, no durations, no audio. Animate after approval.

What is "crisper text generation" for?

The catalog description. Use this row when the still has to hold lettering — labels, posters, UI in frame. If the type fails, re-roll here. Do not hope a video model will typeset it in motion.

Which aspect ratios are listed?

1:1, 4:3, 3:4, 16:9, 9:16. Set the one you will ship. The video row should inherit a still that is already the right shape.

Can I use reference images?

The record allows up to 4 references and does not require one. References pin a stills job. They are not a substitute for a driving video, and this is not a motion-control model.
