Is Chaos Veras worth it for architects in 2026?
For concept work inside Revit, SketchUp, Rhino or Archicad, Chaos's own record makes a strong case: Veras renders from your live model, runs Nano Banana 2, Veo 3.1 and GPT-6 Astra, and since 5.2 can bake generated geometry back into the host. Plans start at $16.90 a month billed annually. ArchiGen has not tested it.
In April 2026 the headline feature of Veras 4.3 was a reference image type called Design Lock, which Chaos's own release notes said worked about three times in four. Six months and nine releases later, the 5.2 announcement describes an agent that reads up to 12 reference images and writes walls, floors, roofs, doors and windows into Revit as native elements. The pace is the first thing any review has to reckon with. Anything written about Veras in the spring describes a different tool.
Including this page. An earlier version reviewed 4.3 using project tests ArchiGen did not carry out, and misdescribed parts of the release. This version uses only the public sources listed at the end.
AI ideation plugin for seven design hosts, built into Enscape, V-Ray and Corona, plus a web app. Generates images and video from the host view and, since 5.0, 3D assets baked back into Revit, Rhino and SketchUp. Runs on Chaos Credits.
What Veras says it is
Chaos calls Veras an "AI creative partner for architects & designers." The more useful line is in its explainer, What is Veras?: it "uses your existing model as a substrate and generates alternative visual ideas without altering the underlying BIM geometry." Sliders for geometry override and material strength set how far it may wander from your massing. EvolveLAB's fingerprints remain: the web app lives at veras.evolvelab.io, per Chaos's documentation, and release notes post to the EvolveLAB forum.
Chaos is candid about the ceiling. The same explainer positions Veras as "an ideation and concept exploration tool rather than a replacement for final product renders." ArchiGen argues the point in Veras as a substrate for creativity, not accuracy. Treat the output as a sketch with good lighting.
Where it runs now
The Veras product page lists Revit, SketchUp, Rhino, Archicad, Vectorworks, Forma and Allplan as hosts, plus Enscape, V-Ray, Corona and a web app. Writing in Digital Production in May 2026, Bela Beier reported Veras arriving inside V-Ray and Corona beyond Enscape, under one credit system. Chaos's press release on its ArchDesign collection says the collection includes Enscape, Enscape Impact, Veras, Envision, Chaos Cosmos and Chaos Cloud. The consequences are unpacked in Veras native in Enscape, V-Ray and Corona.
What changed after 4.3
For the record, 4.3 itself shipped four things, per Chaos's 4.3 post and EvolveLAB release thread dated 2 April 2026. Design Lock extracts "detailing, trim profiles, railing patterns, molding proportions, and panel layouts" from a reference image, limited to one design reference per render at a stated 75% success rate. Video Combine stitches several video renders into one output. Canvas Filters add brightness, contrast, saturation and blur sliders, saved to the cloud per render. Drag-and-drop thumbnails turn a past render into the next source. Sensible, and quickly overtaken.
| Version | When | What it added, per the source |
|---|---|---|
| 4.3 | Apr 2026 | Design Lock, Video Combine, Canvas Filters, drag-and-drop thumbnails (Chaos) |
| 4.4 | May 2026 | Rotate Image, Modify and Replace render selection modes, cloud storage tracking (Chaos) |
| 4.5 | May 2026 | Smart Selection, shareable gallery links, background removal, Describe Source Image via Florence 2 (Chaos) |
| 4.6 | Jul 2026 | Google Veo 3.1 in three tiers, first and last frame animation, 4, 6 or 8 second clips (Chaos) |
| 4.7 | Jul 2026 | Video editing with Gemini Omni, Revit 2027 support (reseller changelog) |
| 4.8 | Aug 2026 | Grok Imagine image engine and Grok video models (reseller changelog) |
| 4.9 | Aug 2026 | Insert images on the canvas, 3D viewer display styles, Revit 2021 to 2023 support ended (reseller changelog) |
| 5.0 | Late Aug 2026 | Image to 3D: match a render to a Cosmos asset or generate assets with Tencent HY3D or Microsoft Trellis2, placed into Revit, Rhino or SketchUp (Chaos); new MODEL tab with object detection (reseller changelog) |
| 5.1 | Sep 2026 | Proxy Bake, Place from Gallery, Microsoft TRELLIS 2.0 (reseller changelog) |
| 5.2 | Oct 2026 | Agent Mode with GPT-6 Astra or Claude Opus 5.5, native geometry baking, Material Generator (Chaos) |
Rows marked Chaos come from What's new in Veras, the 4.6 post, the 5.0 post and the 5.2 post. The rest come from the changelog kept by design8, a Chaos reseller, cross-checked against EvolveLAB forum threads. Dates differ between sources, sometimes by weeks: Chaos's 4.3 post is dated 17 June, more than two months after the 2 April forum thread.
The arc is obvious once it is laid out. Veras spent the spring polishing a renderer and the autumn becoming a modeller. The 5.0 post promises an end to "the slow, manual rework of rebuilding geometry from scratch," and in 5.2 SketchUp gets editable groups and Rhino gets NURBS alongside native Revit elements. What that claim must survive is covered in Veras 5 image to 3D for BIM.
Which AI engines does Veras use?
Veras 4.0 moved to a Render Engine 7 built on Google's Nano Banana Pro, and AEC Magazine noted the earlier Stable Diffusion engines stayed available. Today Chaos's product page names Nano Banana 2, GPT Image, Gemini Omni, Veo 3.1 and GPT-6 Astra. The 5.0 post adds Grok Imagine for images and clips up to 15 seconds, Tencent's HY3D and Microsoft's Trellis2 for image to 3D, and Lotus (free) and Vision Banana (15 credits) for depth of field.
That is the shift worth noticing. Veras no longer sells a model; it sells a seat where everyone else's models sit, wired into the software architects already have open. Whoever wins the next model race, Chaos intends to rent it to you inside Revit.
Veras or Nano Banana: which is better for architects?
It is a false choice. Nano Banana 2 is one of Veras's engines, and Chaos prices its plans in Nano Banana 2 images. The difference is context. Veras feeds the model your live host view as a substrate; using Nano Banana directly means exporting a screenshot and prompting, much like the upload-first tools in Chaos Veras vs Rendair AI. For what the raw model does with drawings, ArchiGen's documented GPT Image 2 vs Nano Banana 2 floor plan comparison is one of the few tests on this site that ArchiGen actually ran. For a Revit office that wants many directions fast, the wrapper earns its fee.
What it costs, in credits
The Veras page lists Starter at $16.90 a month billed annually ($202.80 a year) with 500 credits, "approximately" 50 Nano Banana 2 1K images or 50 AI videos a month. Pro is $29 a month billed annually ($348) with 2,000 credits. Ultra carries 6,000 credits with no public price. Credits are shared between image and video, annual billing saves "up to 50%," and the trial gives 14 days and 100 credits, which Chaos equates to 10 Nano Banana 2 images or 10 videos. That puts a 1K image at roughly 10 credits.
Two rules matter more. The Chaos Credits page says plan credits "reset at the start of each billing cycle and do not roll over." And the agent is expensive: Chaos's October offer of 2,000 free credits for model generation is based on "around 500 credits per model," varying by complexity. One agent-built model costs about 50 images. Digital Production reported the bundled monthly allowances inside the renderers as 100 credits for Solo, 500 for Premium and 1,500 for Collection.
Distrust third-party price summaries. AIToolsBakery's review, updated August 2026, quotes "roughly $29 to $59 a month" and a 30-render, 15-day trial. Only the $29 figure matches Chaos's current page; the trial does not.
The limits, on Chaos's own word
The candid caveats are Chaos's own. Design Lock shipped at 75% success. Veras is pitched for ideation, not final renders. The 5.2 agent flags unknowns with "?" markers where it guesses from reference images, which is honest and a reminder that an image is not a survey. The reseller changelog records Revit 2021 to 2023 support ending in 4.9.
Independent voices add little that is first-hand. AIToolsBakery says its review draws on documentation and G2 and Capterra ratings, and lists inconsistent detail across views as a weakness. Beier's line in Digital Production is the sharpest: credits turn AI ideation into "something you may want to track like any other billable resource," and new integrations "still need a proper test pass before you trust them in production." Before trusting an older verdict, see how to retest Veras after an old review.
Who it suits
On the evidence, offices modelling in Revit, SketchUp or Rhino, especially those already paying for Enscape or the ArchDesign collection, get the most: fast directions from the live model, video inside the host, and now a route from render back to geometry. Dependable final imagery still needs a renderer and a person. A Revit 2023 office needs an upgrade first.
Six months ago Veras was a renderer that sketched. Now it is a modeller that renders, and the invoice comes in credits.
