## My Recommendation
|
|
|
|
Start with **Replicate** because:
|
|
|
|
1. ✅ No upfront cost (vs Stability's $10 minimum)
|
|
2. ✅ Better quality than DALL-E 2
|
|
3. ✅ Can try multiple models to find what works
|
|
4. ✅ Cheapest per-image for low-medium volume
|
|
5. ✅ Can switch to Stability AI later if needed
|
|
|
|
**Next Steps:**
|
|
- I can add Replicate support (30 min of work)
|
|
- Test with SDXL Inpainting first
|
|
- Try LaMa for object removal
|
|
- Fall back to Stability if needed
|
|
|
|
Would you like me to add Replicate support?
