OpenAI: GPT Image 2 API

gpt-image-2 (officially launched as part of ChatGPT Images 2.0) is OpenAI's most advanced image synthesis engine, integrated directly into the GPT-5.4 backbone. Unlike previous pipeline-based models, it features Agentic Reasoning, allowing the model to "think," plan, and search the web for real-time context before rendering a single pixel. It delivers near-perfect text rendering (~99% accuracy) across multiple languages including CJK scripts. With its 4K resolution support and advanced spatial intelligence, gpt-image-2 can generate up to 8 coherent images in a single request, maintaining perfect character and object continuity. In 2026, it is the primary choice for professional UI/UX prototyping, cinematic assets, and high-fidelity branding.
