AI Models

Archvisio offers several AI image models, each strong at something different. Pick one in the model selector when you generate or edit a render, or leave it on Auto. The credit costs below are for a 1K render; higher resolutions cost more (see Credits & Plans).

Render Models

Model	Best for	Credits (1K)
Auto	Picks the model for you from your inputs (see below)	depends on the pick
Nano 2	Best all-rounder, native 4K output, up to 14 references	220
Nano 2 Lite	Fastest, low-cost drafts	60
GPT Image 2.5	Richest materials and staging, up to 16 references	170 (medium quality)
Seedream 5 Pro	Cinematic light and atmosphere, up to 10 references	190
Flux 2 Pro	Photorealistic results, up to 8 references	180
FLUX 3	Stays most literal to your drawing, up to 10 references	140
Z-Image Sketch	Geometry-locked renders from a single sketch	40

Nano 2 costs 330 credits at 2K and 440 at 4K. Flux 2 Pro and FLUX 3 cost 300 at 2K. GPT Image 2.5 has a low quality tier (50 credits) and a high one (550 credits). Very expensive settings can be restricted for team members by a workspace admin.

What Auto picks

• A plan, drawing or site photo — Nano 2
• Text only — Nano 2 Lite
• A single sketch, nothing else — Z-Image Sketch
• Editing an existing render — GPT Image 2.5

Editing Models

The edit tool offers GPT Image 2.5 (the default for edits) and Kontext Pro (fast, low-cost edits, 100 credits), plus the other render models that can edit an image.

Paint mode (inpaint and remove) has its own quality setting: High uses Flux Fill (150 credits) and Quick uses Z-Image Inpaint (40 credits).
