Want to quickly generate Xiaohongshu-style AI image-text content but struggling with time-consuming manual layout and image sourcing? RedInk is an open-source AI content generation tool for Xiaohongshu that combines the image generation capabilities of Nano Banana Pro (Gemini 3 Pro Image Preview), allowing you to input a single sentence and generate complete image-text posts with a cover and up to 15 content pages.
Core Value: After reading this article, you'll learn how to configure the Nano Banana Pro API in the RedInk project (via the APIYI platform), master the complete configuration process for text and image generation, and achieve one-click output from concept to finished product.
Core Capabilities of the RedInk Project
RedInk is an open-source AI content generation tool for Xiaohongshu developed by @HisMax, automating the entire workflow from creative ideas to image-text content through AI models.
| Core Capability | Technical Implementation | Xiaohongshu Content Value |
|---|---|---|
| One-Sentence Generation | AI outline planning + batch image generation | Input a topic, automatically generate 15-page image-text posts |
| Three-Step Workflow | Outline → Cover → Content Pages | Structured production with mid-process editing support |
| Editable Outline | User-customizable chapter descriptions | Flexible adjustment of content structure and style |
| Batch Image Generation | Up to 15 concurrent generations | Rapid completion of entire image-text material sets |
| Single Page Redraw | Style consistency maintenance | Optimize unsatisfactory images |
| Web Visual Configuration | GUI API configuration | No need to manually edit YAML files |
RedInk's Three-Step Workflow
RedInk automatically generates Xiaohongshu content through three consecutive stages:
- Outline Generation: AI generates a structured outline based on a user-input one-sentence topic, including multiple chapters and descriptive text for each page
- Cover Creation: Generates cover images that match Xiaohongshu aesthetics based on user-selected style preferences
- Content Pages Generation: Batch generates illustration pages for each chapter, with a default maximum of 15 pages, supporting concurrent acceleration
Tech Stack:
- Backend: Python 3.11+ + Flask + uv package manager
- Frontend: Vue 3 + TypeScript + Vite + Pinia
- AI Capabilities: Text generation (GPT-4o / Gemini 2.0 Flash) + Image generation (Nano Banana Pro / DALL-E)
Why Choose Nano Banana Pro as Image Generation Engine?
Nano Banana Pro (i.e., Gemini 3 Pro Image Preview) has unique advantages in Xiaohongshu content generation scenarios:
| Comparison | Nano Banana Pro | DALL-E 3 | Midjourney |
|---|---|---|---|
| Text Rendering | Clear rendering of Chinese/English titles/labels | Text easily blurred/distorted | No precise text support |
| Style Consistency | Supports 5 characters/elements consistency | Difficult to maintain style across images | Requires manual seed adjustment |
| Xiaohongshu Aesthetics | Adapted to young female aesthetic preferences | Western-oriented style | Artistic but not lifestyle-oriented |
| Batch Generation Speed | 30 sec/image (2K), supports concurrency | 40-60 sec/image | No API batch support |
| API Cost (APIYi) | $0.05/image | $0.04/image (1024×1024) | No API support |
Conclusion: Nano Banana Pro's text rendering capability and style consistency are most suitable for Xiaohongshu content production, especially for scenarios requiring embedding Chinese titles and product labels in images.

Configuring Nano Banana Pro API (APIYi Platform)
Step 1: Obtain APIYi Platform Key
- Visit api.apiyi.com to register an account
- Top up to get credits (supports Alipay/WeChat/USDT)
- Copy the API Key from the console (format:
sk-xxx)
Recommended Top-Up Plans:
- Testing purposes: $10 (approximately 200 images)
- Daily use: $50 (approximately 1000 images, includes 10% bonus)
- Bulk production: $100+ (20% bonus, unit price reduced to $0.04/image)
Quick Test: New users on the APIYi platform receive free test credits to experience Nano Banana Pro image generation. Visit imagen.apiyi.com for online testing.
Step 2: Configure Text Generation API (GPT-4o)
Hongmo's text generation is used to create outlines, titles, and descriptions. GPT-4o model is recommended (strong logical reasoning capability).
Configure via Web Interface (Recommended):
- Open Hongmo web interface
http://localhost:12398 - Click the Settings (⚙️) icon in the upper right corner
- In the Text Generation Service section, fill in:
- Provider Type: Select
OpenAI Compatible - API Key: Paste your APIYi platform key (sk-xxx)
- Base URL: Enter
https://vip.apiyi.com/v1 - Model Name: Enter
gpt-4o
- Provider Type: Select
- Click Save Configuration
Configure via YAML File (Advanced Users):
Edit the text_providers.yaml file:
active_provider: apiyi
providers:
apiyi:
type: openai_compatible
api_key: "sk-your-apiyi-key"
base_url: "https://vip.apiyi.com/v1"
model: "gpt-4o"
Configuration Validation: Enter a test topic in the Hongmo interface (such as "Spring Fashion Guide"), click generate outline. If it successfully returns a chapter list, the configuration is correct.
Step 3: Configure Image Generation API (Nano Banana Pro)
Hongmo's image generation supports two methods to integrate Nano Banana Pro:
Method 1: Via OpenAI Compatible Interface (Recommended)
Advantages: Simple configuration, uses the same API Key as GPT-4o
Configure via Web Interface:
- In the Hongmo settings page, find the Image Generation Service section
- Fill in the following parameters:
- Provider Type: Select
OpenAI Compatible - API Key: Paste your APIYi platform key (sk-xxx)
- Base URL: Enter
https://vip.apiyi.com/v1 - Model Name: Enter
gemini-3-pro-image-preview - High Concurrency Mode: Check (supports concurrent generation of 15 images when enabled)
- Provider Type: Select
- Click Save Configuration
Configure via YAML File:
Edit the image_providers.yaml file:
active_provider: apiyi_nano_banana
providers:
apiyi_nano_banana:
type: image_api
api_key: "sk-your-apiyi-key"
base_url: "https://vip.apiyi.com/v1"
model: "gemini-3-pro-image-preview"
high_concurrency: true
Configuration Parameter Descriptions:
| Parameter | Description | Recommended Value |
|---|---|---|
type |
API type | image_api (OpenAI compatible format) |
api_key |
APIYi platform key | sk-xxx (obtained from console) |
base_url |
API endpoint address | https://vip.apiyi.com/v1 |
model |
Model identifier | gemini-3-pro-image-preview |
high_concurrency |
High concurrency switch | true (recommended for batch generation) |
Method 2: Via Google GenAI Native Interface
Advantages: Direct connection to Google API, suitable for users with existing Google Cloud accounts
Configuration Example (for reference only, Method 1 is recommended):
active_provider: google_gemini
providers:
google_gemini:
type: google_genai
api_key: "your-google-api-key"
model: "gemini-3-pro-image-preview"
high_concurrency: false # Recommended to disable for GCP trial accounts
⚠️ Note: Google's official API requires overseas credit card binding, and pricing is $0.24/image (4K). Using APIYi platform (Method 1) is recommended, with costs only 20% of the official rate.
Step 4: Configuration Validation and Testing
Generation Test Workflow:
- Enter a topic on the Hongmo homepage:
"Spring Japanese Style Fashion Recommendations" - Click Generate Outline, wait for AI to return chapter structure
- Click Generate Cover, view cover image effect
- Click Generate Content Pages, batch generate 15 illustrations
Expected Results:
- Text generation: 5-10 seconds to return outline
- Cover generation: 30-60 seconds to return 2K resolution cover
- Content page generation: 2-5 minutes to complete 15 images (concurrent mode)
Common Error Troubleshooting:
| Error Message | Cause | Solution |
|---|---|---|
401 Unauthorized |
Incorrect API Key | Check if the key is copied correctly, prefix should be sk- |
404 Model Not Found |
Incorrect model name | Confirm gemini-3-pro-image-preview is entered |
429 Rate Limit |
High concurrency/insufficient balance | Disable high concurrency or top up balance |
Connection Timeout |
Network connection issue | Check if Base URL is https://vip.apiyi.com/v1 |
