Neural Atelier NA01 is a professional ComfyUI node for fashion visualization and product photography. It orchestrates Google's Gemini AI models to transform sketches, materials, and briefs into photorealistic product images.

Architecture

User Input → Gemini 3 Flash (Prompt Orchestration) → Nano Banana Pro (Image Generation) → Output

Gemini 3 Flash (gemini-3-flash-preview): Analyzes your inputs and generates an optimized prompt
Nano Banana Pro (gemini-3-pro-image-preview): Generates the final high-quality image

Installation

Copy the entire comfyui_neural_atelier folder to your ComfyUI custom nodes directory:
```
ComfyUI/custom_nodes/comfyui_neural_atelier/
```
Install dependencies:
```
pip install -r requirements.txt
```
Restart ComfyUI

NA01 Verify API Key

Utility node to verify your Gemini API key.

NA01 Get Profiles

Utility node to list available profiles for a prompt pack.

Prompt Packs

Located in configs/, organized by use case:

01_Senior_Technical_Fashion_Designer: Sketch-to-photo translation
02_Physics_Simulation: Ghost mannequin and hanger presentations
03_Macro_Details: 2x2 detail grid compositions
04_Technical_Illustration: Isometric schematic diagrams
05_Exploded_View: Photorealistic exploded view infographics

Output Logging

All executions are logged to:

ComfyUI/output/neural_atelier/NA01/YYYY-MM-DD/[run_id]/

Files per run:

run.json: Complete execution metadata
nano_banana_prompt.txt: Generated prompt
gemini_flash_response_raw.txt: Raw API response
request_manifest.json: Input configuration

API Key Configuration

You can provide your API key in two ways:

Node Input: Enter directly in the gemini_api_key field
Environment Variable: Set GEMINI_API_KEY in your environment

Security

API keys are never written to disk
All logs automatically redact authentication data
Keys can be verified without exposing them
