When an AI platform starts stacking up more than 40 models from over 20 providers under a single API key, developers no longer have to choose between the hottest video generator and the one that fits their budget. Protoface, a generative media inference platform, made that leap this week, broadening its unified API to include heavyweights like Kling 3.0 Pro, Seedance 2.5, Wan 3.0, and Google’s Veo 3.1, alongside image, audio, and 3D generation tools.
Protoface adds Nano Banana 2, Grok Imagine, Wan 3.0, and more generative AI models to its API, alongside optimized MiniMax H3 inference from $0.01 per second.
The expansion means developers can now tap video models such as Kling 3.0 Pro, Seedance 2.5, Wan 3.0, Google’s Veo 3.1, xAI’s Grok Imagine, and Runway Gen-4 Turbo without juggling multiple accounts. On the image side, Protoface is serving Google’s Nano Banana 2, OpenAI’s GPT Image 2, and FLUX.2. Audio generation comes via ElevenLabs’ Eleven Music and Eleven v3, while Tripo H3.1 handles 3D assets for game development and related workflows. All of it runs through the same API key that already powers MiniMax H3, Protoface Realtime Avatar, and other hosted models.
Protoface leans on what it calls autoresearch and proprietary inference optimizations to bring down the cost of running open-weight generative media models. Its optimized MiniMax H3 inference starts at $0.01 per second, with even cheaper tiers available: FastH3 begins at $0.0035 per second and LTX 2.5 Fast at $0.003 per second. That pricing structure is a direct pitch to developers who want top-tier output without the usual cloud bill.
Creators and developers can pair Protoface’s optimized open-weight models with proprietary ones from other providers, skipping the hassle of separate accounts, API keys, or billing relationships. The API is pay-as-you-go, so there’s no subscription barrier to entry. For those who prefer a more hands-on approach, Protoface Studio offers a browser-based video creation interface that doesn’t require any coding.
“Developers want to use the best model for each task without having to maintain a separate integration for every provider,” said Jason Mehta, engineer at Protoface. “With Protoface, developers can access Kling 3.0 Pro, Seedance 2.5, Wan 3.0, and our optimized MiniMax H3 models using the same API key.”
The models are already being put to work by enterprises and developers building AI video applications, product imagery, marketing and sales collateral, educational and training videos, e-commerce content, and social media posts. The unified access point is designed to cut down on the integration overhead that typically slows down production pipelines.
Developers can get started with MiniMax H3 by grabbing a free API key at protoface.com. Full pricing and the complete model catalog are listed at protoface.com/models, with API documentation available at docs.protoface.com. The move follows Protoface’s August launch of Protoface Studio and the Protoface API.
About Protoface
Protoface provides generative media inference for AI applications, with a focus on cost-efficient inference for open-weight models. The Protoface API gives developers access to video, image, audio, and 3D models through a unified, pay-as-you-go platform. Protoface Realtime enables enterprises and developers to create lifelike digital humans for customer support, sales, coaching, education, and training. Protoface Studio provides a user-friendly interface for AI video creation, supported by Protoface’s inference infrastructure.

Why it matters: Consolidating dozens of leading AI models behind a single API key removes a major friction point for developers who need flexibility without the overhead of managing multiple vendor relationships. By pricing optimized open-weight inference so aggressively, Protoface is pushing the cost of experimentation down, which could accelerate how quickly AI-generated video and imagery move from novelty to standard production tools.
