OpenAI's GPT-6.1 Sol Powers Higgsfield's Ascent to Top ChatGPT Plugin for Professional Creative Workflows

OpenAI's GPT-6.1 Sol reasoning model has become the backbone for Higgsfield AI's rapid emergence as the dominant creative automation plugin on ChatGPT, enabling professional CGI and 3D asset generation directly within the platform. Higgsfield, the San Francisco-based AI-native creative suite with 30 million users across 238 countries, reached the #1 position among ChatGPT plugins in September 2026—surpassing competitors including Runway, OpenAI's own image generator, Figma, and Invideo—by combining GPT-6.1 Sol's reasoning capabilities with its own multimodal generation models to handle end-to-end production workflows.
