About GPTProto

GPTProto is the most affordable way to access every major AI model — GPT, Claude, Midjourney, Suno, and the latest image and video models — through one API. Same models you use today, at lower prices than other platforms, pay-as-you-go with no subscription and no lock-in. Use Cases And Features 1. Automated marketing & social video: Generate short marketing or social videos straight from a text prompt. Send a script or product description to GPTProto and route it to a text-to-video model — Sora 2 when you want higher fidelity, Kling 2.6 or Seedance 2.0 when you need a lower cost per clip. Every model sits behind one OpenAI-compatible endpoint, so you can swap models for the same prompt by changing a single parameter. 2. Image-to-video at scale: Turn static images into short videos in bulk. Feed product photos or stills to image-to-video models like Seedance 2.0, Kling, or Hailuo to produce animated product clips, ad creatives, or thumbnails. Pay-as-you-go billing with volume discounts keeps per-clip cost down across thousands of renders, and built-in failover reroutes to another provider if one goes down, so batch jobs don’t stall. 3. Video inside an AI agent pipeline: Add a video step to a multimodal agent or workflow. With a single API key covering text, image, video, and audio, an agent can write a script, generate scene images, turn them into video, and add a voiceover — without wiring up four separate vendors. The OpenAI-compatible interface drops into existing stacks like LangChain, n8n, or Cursor with almost no extra setup.
