Pros & cons
Advantages
- Specialised models trained on game art and concept art reduce generic output
- Custom model training lets you develop a consistent visual style across projects
- Decent free tier allows genuine experimentation before committing to paid plans
- API integration means you can build generation into existing pipelines or tools
Limitations
- Quality and consistency depend heavily on how well you write prompts and train custom models
- Free tier has limited generation credits, so serious production work requires a paid subscription
- Generated assets may need manual refinement or post-processing to meet professional standards
Use cases
