# Nuit vs Krea for Architecture: When Each Fits

**Krea and Nuit are increasingly compared because Krea — one of the most powerful AI creative suites on the market — is now actively selling to architects. It has a dedicated architecture page, a partnership with the architecture firm Henning Larsen, and a strong image model in Krea 2. But Krea is a general-purpose image, video, and 3D suite, while Nuit is built specifically for architectural concept design. The difference that matters is consistency: in Krea, keeping one building coherent across views is your manual job; in Nuit, it is a property of the project.**

This is the focused, head-to-head comparison. If you want the single most powerful image generator and you are willing to drive the consistency yourself, Krea is a serious tool. If you want the building to stay the same across exterior, plan, and interior without re-tuning references every time, this piece explains where Nuit fits.

For context on why project-level consistency is the real problem, see [keeping AI designs consistent across a project](/blog/consistent-ai-designs-across-project/) and [what end-to-end AI design means](/blog/what-end-to-end-ai-design-means/).

## What Krea actually offers

Krea is an "AI creative suite for everyone" with an enormous toolset: image generation on its own Krea 2 model (plus a Turbo variant), Realtime sketch-to-render that updates live as you draw, 4K video, 3D objects, upscaling to very high resolutions, and a node-based pipeline with an agent. Its reference system is among the strongest in the segment — style, structure, and subject references with adjustable weights, moodboards that turn 5–15 images into a style profile, and LoRA training available to all users.

Where Krea is strong:

- **Raw image power.** Krea 2 is a top-tier model, and the Realtime sketch-to-render mode is genuinely loved by architects for fast iteration.
- **Breadth.** Video, 3D, upscaling, and nodes mean a lot of deliverables live in one place.
- **Reference depth.** For users willing to tune them, the reference controls are powerful and granular.
- **Reach.** Over 20 million users and an active push into the AEC market.

## Where Krea hits its limits for architecture

The same generality that makes Krea powerful is what makes it shallow for whole-project architectural work:

- **Consistency is per-generation, not project-scoped.** Running one building through exterior, lobby, aerial, and evening views means re-establishing references each time. LoRA training would need images of the building — which don't exist for an unbuilt concept.
- **No architectural modes.** There is no masterplan, plan, or interior mode; the workflow is assembled through prompt-craft and community nodes, and floor plans aren't meaningfully supported.
- **No exploration tree.** Generation history is flat — there is no lineage of what branched from what.
- **Sprawl.** 64+ models and dozens of tools create real overhead, and Krea is generative-only, with no BIM connection. Trustpilot sits around 2.7/5, with recurring billing complaints.

## How Nuit approaches the same work

Nuit makes the **project** the unit of work. Saved reference images of the project feed every generation automatically, so consistency strengthens as you go rather than being re-built each time.

Against Krea specifically:

- **Consistency by default.** No reference-weight tuning per generation — the project's portfolio of approved images drives coherence across facade, plan, and rooms.
- **Architectural modes.** Exterior, plan, and interior are connected parts of one project.
- **Branching tree.** Every image is a branch point; the full exploration history is saved.
- **No model sprawl.** One focused workflow instead of a 64-model catalogue to navigate.

## Nuit vs Krea: side by side

| | Nuit | Krea |
|---|---|---|
| Built for | Architectural concept design | General creative suite (now courting AEC) |
| Consistency across views | Project-scoped, automatic | Per-generation, manual reference tuning |
| Architectural modes (masterplan/plan/interior) | Yes | No |
| Floor plans | Yes | Not meaningfully |
| Exploration history | Branching lineage tree | Flat history |
| Live sketch-to-render | No | Yes (Realtime — a strength) |
| Video / walkthrough | No | Yes (4K) |
| Model catalogue | Focused workflow | 64+ models |
| Free tier | 10 generations, no card | 100 units/day |
| Paid entry | Mid-tier | USD 9/month (Basic) |

## When to use which

**Choose Krea if** you need the most powerful single-image generation, live sketch-to-render, 3D objects, video walkthroughs, or final hero-shot polish — and you are comfortable managing consistency yourself with its reference controls.

**Choose Nuit if** your work is a whole project that must stay coherent — one building across exterior, plan, and interior, or many rooms of one home — and you would rather that coherence be automatic than a per-generation chore. Architectural modes and floor plans are where Nuit leads.

**Use both if** you want project coherence and single-image power: build the project in Nuit, then take chosen frames into Krea for Realtime refinement or a walkthrough video.

The one-question test: is your deliverable a single image (or a video), or a coherent multi-view project? Single — Krea's power is hard to beat. Multi-view — Nuit's project model is the reason the building stays the same building.

## Against Krea's moodboards

Krea's moodboards capture a "taste," not "this exact building." For an unbuilt concept there is nothing to train a LoRA on. In Nuit, the project portfolio grows with every approved generation, so consistency increases over the life of the project instead of being reconstructed for each render.

## Conclusion

Krea is the more powerful generator and the better tool for single images, live rendering, and video. Nuit is the better tool when the unit of work is a project that has to stay consistent across views — without re-tuning references every time. As Krea pushes harder into architecture, the distinction to keep in mind is breadth versus project depth.
