Frequently asked questions
What is the difference between Standard and HD in DALL-E 3?
Standard uses less compute and is faster. HD generates images with more detail and consistency at the cost of roughly 2× the price. For UI mockups or quick ideation, Standard is usually sufficient. For final client deliverables or print-quality art, HD is worth the premium.
Is Midjourney charged per image or flat monthly?
Midjourney uses flat monthly plans that include a set number of fast GPU-minutes. The Basic plan ($10/mo) gives roughly 200 standard images; Standard ($30/mo) gives about 900; Pro ($60/mo) offers unlimited relaxed-mode generations. Heavy users who exceed their fast-mode allowance pay overage.
Can I use the Stable Diffusion API for commercial projects?
Most hosted Stable Diffusion APIs (DreamStudio, Stability AI, Replicate) allow commercial use under their terms of service. Always check the specific API provider's license. Self-hosting Stable Diffusion models locally has no per-image API cost.

Choosing the right pricing model
Pay-per-image APIs like DALL-E 3 suit low-volume or unpredictable workloads where you do not want a fixed monthly commitment. Flat-rate plans like Midjourney make sense for creatives who generate images daily. At 500+ images per month, Midjourney Standard often beats DALL-E 3 Standard by a wide margin.
Reducing image generation costs
Cache and reuse generated images wherever possible — store them in a CDN and serve the same image to multiple users rather than regenerating. Use smaller sizes for thumbnails and only generate full-resolution images when the user specifically requests one. Batch requests during off-peak hours to leverage any provider discounts.
