Soul

Soul is an image generation model made by a company called Higgsfield. Think of it as a tool focused on producing photorealistic images.

While Higgsfield builds Soul and its video model DoP in-house, it also brings in models from other companies like OpenAI, Google, and ByteDance. In other words, Soul is homegrown material Higgsfield made from scratch, and the company mixes in outside material as needed.

What Higgsfield emphasizes is its own engine for arranging these various models — whether in-house or external — according to story flow and composition. Soul is one component in that system, the one responsible for photorealistic images.

The article notes that "Higgsfield is a company that builds its own models, Soul and DoP, while also drawing on models from OpenAI, Google, and ByteDance." In fact, the buzzworthy feature film 'The Curly Hill Boys' and the short 'Adilia Da' used ByteDance's video model Seedance, not Soul. A common misconception is that just because Higgsfield made Soul, it doesn't mean every work the company releases uses Soul.
