Bria AI drops Fibo 1.5 with JSON-native prompts and 4-step generation
Bria AI just released Fibo 1.5, an 8B open-source image model built around structured JSON captions rather than messy text prompts. Thanks to two-stage distillation, it runs in just 4 to 6 steps without CFG, allowing artists to tweak lighting or camera angles without breaking the rest of the scene.
