- mana-image-gen: change default port from 3025 to 3026 to avoid conflict with mana-llm
- Dashboard widgets (12): replace APP_URLS.{app}.dev/prod with internal route paths (/todo, /calendar, etc.)
and remove target="_blank" since all apps are now internal routes in the unified app
- Home page: use goto() for internal apps, keep window.open() only for external apps (matrix, arcade)
- AppRow: remove unused APP_URLS import

# Mana Image Generation Service
|
|
|
|
Local AI image generation using **FLUX.2 klein 4B** model via flux2.c.
|
|
|
|
## Features
|
|
|
|
- **Fast**: Sub-second generation on Apple Silicon
|
|
- **Efficient**: ~4-5 GB RAM (memory-mapped weights)
|
|
- **Open**: Apache 2.0 license (commercial use)
|
|
- **Local**: 100% on-device, no API keys needed
|
|
|
|
## Requirements
|
|
|
|
- macOS with Apple Silicon (M1/M2/M3/M4)
|
|
- 16 GB RAM minimum
|
|
- ~20 GB disk space (model + binary)
|
|
- Python 3.11+
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# 1. Run setup (installs flux2.c + downloads model)
|
|
./setup.sh
|
|
|
|
# 2. Start the service
|
|
source .venv/bin/activate
|
|
FLUX_BINARY=/opt/flux2/flux FLUX_MODEL_DIR=/opt/flux2/model \
|
|
uvicorn app.main:app --host 0.0.0.0 --port 3026
|
|
|
|
# 3. Generate an image
|
|
curl -X POST http://localhost:3026/generate \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"prompt": "A cat wearing sunglasses"}' | jq
|
|
```
|
|
|
|
