On Tuesday, OpenAI announced new multimodal image-generation capabilities that are directly integrated into its GPT-4o AI language model, making it the default image generator within the ChatGPT interface. The integration, called "4o Image Generation" (which we'll call "4o IG" for short), allows the model to follow prompts more accurately (with better text rendering than DALL-E 3) and respond to chat context for image modification instructions. Some users on social media initially reported confusion since there's no UI indication of which image generator is active, but you'll know it's the new model if the generation is ultra slow and proceeds from top to bottom. The previous DALL-E model remains available through a dedicated "DALL-E GPT" interface, while API access to GPT-4o image generation is expected within weeks.
