Nano Banana 2 Is Now in Rendair AI

Google just released their best image generation model yet, and it's already inside Rendair.

At Rendair, our job is to make sure you always have access to the most capable AI the moment it becomes available, without needing to benchmark models yourself, manage multiple tools, or figure out which subscription covers what.

That is why we integrated Google's Nano Banana 2 (Gemini 3.1 Flash Image) into Rendair Chat from day one.

Nano Banana 2 is Google's answer to a question architects ask constantly: why do I have to choose between speed and quality? The model combines the advanced intelligence of Nano Banana Pro with significantly faster generation speed, and at a lower cost. For the first time, you get Pro-level capabilities without the Pro-level wait.

Here is what changed, and what it means for your workflow inside Rendair.

What We Found in Testing: The Key Upgrades

We put Nano Banana 2 through real architectural scenarios before rolling it out. Here are the improvements that matter most for design work:

1. Real-World Knowledge That Actually Understands Architecture

Nano Banana 2 is grounded in Gemini's real-world knowledge base, including real-time information from web search. In practice, this means the model has a deeper understanding of specific architectural styles, materials, building types, and spatial contexts.

When you reference a specific design language, material system, or architectural reference, the model recognizes it, and renders it accurately rather than approximating it.

2. Precise Instruction Following

Complex architectural briefs have always been a weak point for AI rendering. A prompt like "warm concrete walls, oak joinery, indirect ceiling cove lighting, north-facing light" demands precision, and previous models often averaged it out.

Nano Banana 2 adheres more strictly to complex prompts. The specific nuances of your brief are captured in the output, not smoothed over. The image you ask for is far closer to the image you get.

3. Subject and Element Consistency Across Frames

For architects building multi-view presentations, phased visualizations, or concept narratives, consistency has always been the problem. Elements shift between renders. Furniture changes shape. Materials drift.

Nano Banana 2 maintains consistency across up to 14 objects in a single workflow. Furniture, fixtures, structural elements, and material choices stay coherent from frame to frame, so you can build a coherent visual story around a design, not a collection of loosely related renders.

4. Flash Speed, Pro Results

The most significant shift is speed: Nano Banana 2 runs on Flash architecture, generating substantially faster than Nano Banana Pro and at a lower cost. For rapid iteration through client feedback, exploring multiple concept directions in parallel, or just moving faster through a project, this directly changes how AI fits into your day.

Workflow Insights & Best Practices

Text-to-Render: More Knowledge, Better Results

Because Nano Banana 2 draws on real-world knowledge, text-to-render prompts that reference specific architects, styles, materials, or typologies now land more accurately. Name the reference, the model knows it.

Pro Tip: Lean into specificity. Reference real materials, named architectural styles, or known building typologies. Nano Banana 2's knowledge base means these references are understood, not just loosely interpreted.

From Sketch to Concept Render

Nano Banana 2 works with your existing design inputs, hand sketches, SketchUp or Revit massing models, clay renders. Upload your base geometry and describe the finish you want. The model's improved instruction following means the style you describe is applied to the structure you provided, without distorting the geometry or conflating the two.

Style Transfer with Reference Images

Getting the exact mood right is often the hardest part of a client brief. With Nano Banana 2, upload a reference image alongside your base geometry and describe the direction you want to take it.

The model's improved world knowledge and instruction following means it understands what you are referencing, and applies materiality, lighting character, and spatial mood accurately. Style is transferred. Structure is preserved. Your building stays your building.

Precision Editing & Design Variations

Nano Banana 2's enhanced instruction following directly improves editing precision. When you ask for a specific change, the model targets only what you specified.

Each edit landed accurately without cascading unintended changes across the rest of the image. This makes AI editing a reliable tool for real client revision rounds, not just a way to generate new starting points.

The Rendair Advantage: Curated Power

Rendair is not just a chatbot, it is a smart architectural rendering ecosystem.

• Smart Model Routing: Different tasks call for different models. Our system knows which model performs best for your specific task, whether that is converting a floor plan, editing an existing render, or generating a photorealistic exterior, and routes automatically.

• Architectural Context Built In: Rendair is configured for architectural use cases. You do not need to engineer your prompts from scratch for every task.

• All-in-One Efficiency: No separate subscriptions for image generation, editing, and rendering software. The best available models, including Nano Banana 2, bundled into one platform built for design professionals.
