OpenAI: GPT Image 1.5 API
OpenAI's latest flagship image model. Moving beyond traditional diffusion artifacts, it uses a full Transformer architecture for "pixel-level reasoning." The core evolution lies in Identity Locking and physical lighting consistency. It supports extreme instruction adherence (e.g., placing objects at specific coordinates) and precise editing, such as changing clothing or lighting without altering the face or background.
