Why do some models cost more?
Credits and costs
Fair pricing that reflects real costs
Every generation on Endlss costs credits. Most models cost 1 credit, but some premium models cost 2 or 3. The reason comes down to what it actually costs us to run them.
AI image and video generation runs on powerful GPUs. Different models require different amounts of compute — a fast, lightweight model like Flux Schnell needs a fraction of the resources that a premium model like Flux Pro 1.1 or Kling 2.0 requires. We pass through the real cost difference, not a markup.
What affects the cost?
Compute, time, and quality
Model size and complexity
Larger models with more parameters produce higher-quality output but require more GPU time. A 14-billion parameter model costs more to run than a 2-billion parameter one.
Generation time
Faster models are cheaper. Flux Schnell generates in 2–4 seconds; Kling 2.0 video takes 60–90 seconds. That GPU time has a real cost.
Output type
Video generation is significantly more expensive than image generation — a single video frame requires the same compute as a full image, and a 5-second video contains many frames.
Provider costs
We use third-party GPU providers to run models. Premium models from providers like Kling charge higher API fees, which we reflect in the credit cost.
