Higgsfield has published open-higgsfield, a Next.js 16 reference app for its newly public generation API. The repository mirrors the composer, gallery, model picker, viewer, and asset pipeline used by the hosted studio, giving developers a complete interface and request pipeline to fork.
The repository passed 3,500 GitHub stars within days of a Higgsfield founder offering $50,000 for a product built on the code that attracts real users. The release ties that incentive directly to paid API usage.
One composer, 38 models
The catalog contains eight image models and 30 video models, all controlled through one prompt composer. Options include Soul 2, Soul Cinema, Seedance 2.5 Edit and Extend, Seedance 2.0 Fast and Mini, Kling 3 Turbo, Standard, Pro, 4K and Motion, plus Wan, Flux, Ideogram, Recraft, LTX, MiniMax, PixVerse, Grok, and Qwen.
Each model declares an allowlist for aspect ratio, resolution, duration, audio, batch size, and accepted media roles. The interface reads those declarations and renders only the controls supported by the selected model.
Each catalog entry also stores its platform price in thousandths of a dollar. The submit button calculates the request cost before submission, including batch quantities. At the rates encoded in the repository, a five-second Seedance 2.5 generation costs about $0.495, while a Soul 2 image costs about $0.011. Entries without published rates remain unpriced. Requests above $5 require a second confirmation, and changing the model, duration, or quantity clears that confirmation state.
