Credits never expire. Buy a pack or roll unused monthly credits forward — they stay on your balance until you spend them. That is a hard advantage over platforms like Higgsfield, where unused allotments typically vanish when the cycle resets. Top up once, shoot when you are ready.
Credits are the studio currency. Almost every generation — image, video, Carousel Shots, upscale, and similar tools — spends them. Costs are per model: lighter models burn less; premium video and image models cost more.
Failed generations always refund. If a job fails, those credits come back — you only pay for successful outputs.
Your balance sits in the header (coin control) and under Settings → Credits. Plans grant a monthly allotment; one-time packs top up when you need more. Exact plan sizes and billing portals differ by product, but the credit meter and model picker work the same way. A $10 top-up is 200 credits (~5¢ each).
Models are chosen inside each tool. Image, Video, Carousel Shots, and AI Influencer each expose the models that fit that job. You do not need every model — match quality and cost to the step you are on. Locking a face with Direct Save is free; Merge and Build use GPT Image 2. Day-to-day stills and carousels usually run on Nano Banana, GPT Image, or Seedream. Motion leans on Kling, Veo, Seedance, and related video models.
Spend smart: batch with a mid-tier model while exploring, then upscale or re-run keepers on a stronger model. Carousel Shots is priced like one image for a full multi-angle set — often cheaper than generating panels one by one.
Key points
Credits never expire
Unused credits stay yours — monthly grants stack, and purchased packs do not time out. Platforms like Higgsfield usually wipe unused credits when the billing period ends. Here you can bank a top-up for a quiet week and burn it on a big shoot later.
What spends credits
Image and video generations, Carousel Shots, upscale, SynthID scrub, and remove-background all deduct credits. Cost follows the selected model.
Direct Save for AI Influencer is free. Most free-tools (compressor and similar) do not spend credits.
Failed generations always refund. Credits return automatically when a job fails — you are not charged for broken runs.
Balance, plans, and packs
Check the coin in the header or Settings → Credits. Plans add monthly credits; packs are one-time top-ups on Pricing. $10 buys 200 credits. Whatever you do not spend stays.
Buy credits when you are mid-batch so you do not stall on a keeper run — or buy ahead knowing they will not evaporate.
Image models
Common picks: Nano Banana (fast / everyday stills), GPT Image 2 (strong faces and Merge/Build), Seedream (detail and alternate looks), plus Grok Imagine, Z-Image Turbo, and Qwen Image Edit when you need those lanes.
Carousel Shots defaults to Nano Banana 2 and can use GPT Image or Seedream — still billed like a single image for the set.

Video models
Video is where credits move fastest. Kling, Veo, Seedance, Gemini Omni, Happy Horse, and Grok Imagine Video cover motion, lipsync-adjacent, and control workflows.
Draft motion on a cheaper/faster option, then spend on a premium pass only for finals.
