2025-12-08 · blog launch post · Higgsfield · original

Topic: Image generation & editing · mode: Launch & promotion · tags: vendor claims

A Higgsfield blog guide to OpenAI's GPT Image 1.5, listed as Hazelnut in Higgsfield's Image section from December 2025. It pitches the model for writing, diagrams, analysis and visual planning rather than stylized artwork, with output up to 1.5K. The post covers inputs such as reference images, sketches and charts, three quality levels and three aspect ratios, then gives a step-by-step guide and practical workflows.
