Models

ArtAPI provides access to multiple image generation engines through a unified API. Model availability depends on your plan.

Available Models

Model ID	Provider	Max Resolution	Speed	Notes
`flux-dev`	fal.ai (FLUX.1 Dev)	1440×1440	~10s	High quality, great for detailed prompts
`flux-schnell`	fal.ai (FLUX.1 Schnell)	1440×1440	~3s	Fast generation, good for iteration
`dall-e-3`	OpenAI	1792×1024	~15s	Excellent prompt adherence, auto-revises
`dall-e-2`	OpenAI	1024×1024	~8s	Faster, lower cost
`sdxl`	Stability AI	1024×1024	~12s	Versatile, strong community fine-tunes
`sdxl-turbo`	Stability AI	512×512	~2s	Real-time generation, lower resolution

Plan availability

Not all models are available on all plans. Check your dashboard to see which models are enabled for your account.

For quality: flux-dev or dall-e-3 — best prompt understanding and output fidelity.

For speed: flux-schnell or sdxl-turbo — suitable for real-time applications or rapid prototyping.

For cost efficiency: dall-e-2 or sdxl — lower credit cost per image.

Supported sizes vary by model. Common values:

TIP

If you specify an unsupported size, the API returns a 400 error with available options. Check model-specific constraints in the dashboard.
