Higgsfield Says GPT-6.1 Sol Built the Same 3D Game Workflow 4x Faster Than GPT-6 Astra at One-Fifth the Cost

Higgsfield AI says GPT-6.1 Sol completed the same 3D game-prototyping workflow as GPT-6 Astra four times faster and at one-fifth the cost, adding an early creative-production test to OpenAI's claim that the new Sol model brings near-Astra performance to lower-cost agentic work. The comparison centers on a single task inside Higgsfield: building a 3D game prototype.
