Higgsfield Open-Sources Creative Studio and Offers $50K

AI video startup Higgsfield has released open-higgsfield, a Next.js 16 reference application that open-sources the complete frontend and backend pipeline of its creative studio. The repository, which quickly surpassed 3,500 GitHub stars, provides developers with a pre-built composer, gallery, model picker, viewer, and asset pipeline. To accelerate adoption, Higgsfield's founder is offering a $50,000 prize to anyone who builds and ships a viable product on top of the Higgsfield API that successfully attracts real users.

The codebase features a unified prompt composer capable of driving 38 different AI models, comprising eight image generators and 30 video generators. The supported lineup includes Soul 2, Soul Cinema, Seedance 2.5 Edit and Extend, Seedance 2.0 Fast and Mini, Kling 3 Turbo, Standard, Pro, 4K, and Motion, alongside Wan, Flux, Ideogram, Recraft, LTX, MiniMax, PixVerse, Grok, and Qwen. Each model defines its own allowlist for parameters like aspect ratio, resolution, duration, audio, batch size, and media roles, allowing the interface to dynamically render only the controls supported by the active model.

For practitioners, the repository serves as a robust blueprint for production-grade media applications. Security and performance are handled via server actions for API calls, httpOnly cookies for API keys, and direct client-to-Vercel Blob uploads. The system also integrates real-time cost estimation directly onto the submission button, calculating prices in thousandths of a dollar. For example, a five-second Seedance 2.5 generation costs approximately $0.495, while a Soul 2 image costs about $0.011. To prevent accidental spending, the interface includes a mandatory double-confirmation gate for any single request exceeding $5.00.
