Fal.ai (signup credits)

New accounts get roughly $20 in trial credits automatically on signup, no application needed, covering image, video, and GPU-class model calls

Multiple sources consistently put this at roughly $20 (some channels previously described 'no free tier,' which is now outdated — 2026 information confirms a signup credit exists). Pure pay-as-you-go pricing, e.g. roughly $0.03/image for Seedream V4, $0.05/second of video for Wan 2.5, and $0.4/second for Veo 3. Once the credit is used up, you need to link a payment method to continue; the vendor hasn't disclosed an expiration date for the credit.

⚠️Per-call pricing for image/video generation isn't cheap — $20 in credit runs out quickly on video models (roughly 50 seconds' worth on Veo 3) — better suited to testing image models or short video clips.
