GPT Image 1.5: 4x Faster AI Image Generator by OpenAI
What is GPT Image 1.5
GPT Image 1.5, released on December 16 2025, is OpenAI’s most capable text‑to‑image model to date. It builds on the GPT‑5.2 multimodal architecture, delivering image generation up to four times faster than GPT 1 while preserving text, logos, and faces with high fidelity. Users can access the model via the GPT Image 1 API or Azure integration, benefiting from 20 % lower pricing for both inputs and outputs. The model supports precise conversational editing—changing lighting or color with a single text instruction—without regenerating the entire composition. GPT Image 1.5 also excels at dense text rendering for posters and infographics. Features such as a “mini” mode for rapid prototyping and advanced editing tools make it suitable for creators, designers, and enterprise brands seeking cost‑effective, high‑quality image generation.
How does GPT Image 1.5 work
GPT Image 1.5, launched December 16, 2025, builds on OpenAI’s GPT‑5.2 multimodal backbone by coupling a transformer encoder with a diffusion generator, enabling rapid text‑to‑image synthesis. The model delivers four‑fold generation speed, reducing complex prompts to under two minutes and simple ones to seconds, and cuts API costs by 20 % compared to GPT Image 1. Precise editing commands preserve lighting, composition, logos, and facial identity, while dense text rendering surpasses competitors for marketing graphics. GPT Image 1.5 is available through OpenAI’s API, Azure and as a free‑credit preview.
Benefits of GPT Image 1.5
