OpenAI is expanding its image-generating feature, gpt-image-1, to other developers and applications, including Adobe's Firefly and tools like Figma and Wix. This follows a surge in usage where over 130 million users created 700 million images in just the first week. Additionally, Microsoft will integrate OpenAI's image generation into its Microsoft 365 Copilot app, enhancing competition with Google in the generative AI market.
