Krea 3: what should stay when the furniture changes?

A room gets different furniture and a can a new setting: which details remain? Read the official inputs and outputs, then distinguish app access, API eligibility, reference limits and the cost of one generation.

Krea 3 launched October 15 and entered our model catalog October 18. On October 19 we checked original inputs and outputs, the user guide and API documentation. These are vendor examples; we did not generate images, request beta access or perform a renovation.

The furniture changes; the room provides the reference

The example supplies an existing room and three furniture references, asking for different seating and a table while retaining the room, rug and reader. Walls, windows and people’s positions remain recognizable as furniture colors, shapes and materials change. It provides a more relevant design reference than an unrelated newly generated room.

Preservation still needs item-by-item inspection. New furniture changes occlusion, shadows and contact, and a similar image does not establish real-world dimensions. The source prompt is shortened and its attempt history is absent. This vendor result illustrates an editing direction rather than proving one-shot success on arbitrary rooms.

Original scene inputOfficial scene input with an orange sofa, blue-green armchairs and a pale round table, with a person reading by the window.
One official input. The source also supplies three product references—a sofa, chair and table—for four images in total. This scene is not an empty room. · Open full-size image
Official edited outputThe edited output retains the room’s broad structure and people’s positions while changing the sofa, chairs and coffee table.
Official 2K example, uncropped. Windows, walls and people anchor the comparison. Check occlusion, shadows and contact points; broad similarity does not prove physical fit or pixel-exact preservation elsewhere. This is model output, not a renovation photograph. · Open full-size image

A new product scene still needs a label check

The can moves from a plain product background into a hand-held scene with ice and citrus. FIZZLE, the flavor words and floral label remain recognizable while composition, angle and lighting change. The editing use is concrete: a familiar product enters a different visual presentation rather than being replaced with an unrelated object.

Before using such an image, inspect letters, label layout, edges and hand occlusion at full size. Recognizable product identity and exact packaging fidelity are different checks. These examples can inspire product scenes and personal work, but do not establish revision count, client approval or sales outcomes.

Original can inputA white can on a plain background, with pink FIZZLE lettering, flavor text and floral doodles.
Official product input. Start with shape, large lettering and flavor text, then enlarge to inspect fine print, patterns and edges. Recognizing a brand name alone is an incomplete check. · Open full-size image
Official scene outputA tilted can with the same label theme, held among crushed ice and cut citrus against a vivid pink background.
Official output. Angle, lighting, reflections, condensation and occlusion change. Switch between complete images at the same scale; the source provides neither a repeat-success rate nor all candidate generations. · Open full-size image

What sits behind eight seconds and six cents?

The launch claims most native-2K edits take under eight seconds. Competitor latency comes from earlier Krea jobs, September 24–October 1, including queues, rather than our simultaneous equal-budget test. The current API also distinguishes default fast and slower high modes. Useful iteration time includes waiting, retries and checking.

$0.06 is the 2K base component, not the final cost of every edit. The API documentation adds $0.02 per 1K reference, $0.07 per 2K reference and $0.02 per high-mode generation. The table assumes four references billed at 1K. It is neither the room example’s invoice nor app compute-unit pricing.

Calculated from Krea API item prices read October 19; one generation, not an executed request.

Match the access path to the preservation requirement

The user guide makes the base Krea 3 available to app users through compute units, while the API remains early access for beta workspaces. The launch describes six references; current API parameters allow eight. With five or more, each reference is limited to 1536 pixels on its longest side. These are source and access scopes, not evidence of a model upgrade today.

For an initial design experiment, start with a scene you own and a focused request that names what should remain, then inspect the result. For exact regional changes, the API documents regional_edit and claims pixel preservation outside the edited area. That mode’s claim does not establish that every launch example used it. We have not verified it through calls; preservation must still be checked against the intended standard.
