Higgsfield AI showcases 4x4 pixel-art sprite sheet built with OpenAI's GPT-Image-2.5

Generative-AI studio Higgsfield AI has published a 4x4 pixel-art sprite sheet generated with OpenAI's newly released GPT-Image-2.5, offering an early look at how the model handles a notoriously difficult image-generation task for game developers. The demonstration arrives just days after OpenAI introduced ChatGPT Images 2.5 on September 8, 2026, rolling the underlying image model out to ChatGPT, ChatGPT Work, and Codex users, alongside two API-accessible variants aimed at professional and enterprise workflows.
