📦 Deployment

Option 1: Docker (Recommended)

The simplest way — one command to start:

docker run -d -p 12398:12398 -v ./history:/app/history -v ./output:/app/output histonemax/redink:latest

Visit http://localhost:12398 and configure your API Key in the Settings page.

Using docker-compose (optional):

Download docker-compose.yml, then:

docker-compose up -d

Docker Notes:

• The container does not include any API Keys — configure them in the web UI
• Use -v ./history:/app/history to persist history
• Use -v ./output:/app/output to persist generated images
• Optional: mount custom config -v ./text_providers.yaml:/app/text_providers.yaml

---

Option 2: Local Development

Prerequisites:

• Python 3.11+
• Node.js 18+
• pnpm
• uv

1. Clone the Repository

git clone https://github.com/HisMax/RedInk.git
cd RedInk

2. Configure API Services

Copy the config templates:

cp text_providers.yaml.example text_providers.yaml
cp image_providers.yaml.example image_providers.yaml

Edit the config files with your API Key and service settings, or configure them later via the Settings page in the web UI.

3. Install Backend Dependencies

uv sync

4. Install Frontend Dependencies

cd frontend
pnpm install

5. Start the Services

One-Click Start (Recommended)

Run the start script to automatically install dependencies and launch both frontend and backend:

• macOS: start.sh or double-click scripts/start-macos.command
• Linux: ./start.sh
• Windows: Double-click start.bat

The browser will automatically open at http://localhost:5173

Manual Start

Start Backend:

uv run python -m backend.app

Visit: http://localhost:12398

Start Frontend:

cd frontend
pnpm dev

Visit: http://localhost:5173

🔧 Configuration

Configuration Methods

The project supports two configuration methods:

1. Web UI (Recommended): Visual configuration via the Settings page after starting the service
2. YAML Files: Edit config files directly

Text Generation Config

Config file: text_providers.yaml

# Active provider
active_provider: openai

providers:
  # OpenAI or compatible API
  openai:
    type: openai_compatible
    api_key: sk-xxxxxxxxxxxxxxxxxxxx
    base_url: https://api.openai.com/v1
    model: gpt-4o

  # Google Gemini (native API)
  gemini:
    type: google_gemini
    api_key: AIzaxxxxxxxxxxxxxxxxxxxxxxxxx
    model: gemini-2.0-flash

Image Generation Config

Config file: image_providers.yaml

# Active provider
active_provider: gemini

providers:
  # Google Gemini image generation
  gemini:
    type: google_genai
    api_key: AIzaxxxxxxxxxxxxxxxxxxxxxxxxx
    model: gemini-3-pro-image-preview
    high_concurrency: false

  # OpenAI compatible API
  openai_image:
    type: image_api
    api_key: sk-xxxxxxxxxxxxxxxxxxxx
    base_url: https://your-api-endpoint.com
    model: dall-e-3
    high_concurrency: false

High Concurrency Mode

• Off (default): Images generated one by one — suitable for GCP $300 trial accounts or rate-limited APIs
• On: Images generated in parallel (up to 15 simultaneously) — faster but requires API support for high concurrency

⚠️ Not recommended for GCP $300 trial accounts — may trigger rate limits and cause generation failures.

---

⚠️ Notes

1. API Quota Limits:

   • Be aware of Gemini and image generation API call quotas
   • GCP trial accounts should keep high concurrency disabled

2. Generation Time:

   • Outline generation usually takes 15-30 seconds
   • Image generation takes time — please be patient (don't leave the page)

Changelog

v1.4.3 (2026-06-30)

• ✨ Default outline length changed to 5 pages when the user does not specify a page count

• 🔧 Added per-record image generation recovery so refreshes or retries reuse existing images instead of spending upstream quota again
• 🔧 Protected history records from empty image overwrites and status regressions; history reads can self-heal from task image folders
• ✨ Added structured Problem Details-style API errors and reusable frontend error cards with copyable diagnostics
• 🐛 Fixed provider connection tests for reasoning models that return reasoning_content or reasoning tokens without final content
• 🧪 Added backend coverage for image API compatibility, history merging, structured errors, cached generation, and reasoning-model connection tests
