Concerns around “unprecedented demand” is likely referring to the recent launch of 4o image generation. When OpenAI updated ChatGPT with its newest image software, it was inundated with demand, causing the company to quickly remove it from the free version to reduce usage.

OpenAI has introduced GPT-4.1, a successor to the GPT-4o multimodal AI model launched by the company last year. During a livestream on Monday, OpenAI said GPT-4.1 has an even larger context window and is better than GPT-4o in “just about every dimension,” with big improvements to coding and instruction following.

GPT 4.1, GPT 4.1 Mini, and GPT 4.1 Nano are all available now—and will help OpenAI compete with Google and Anthropic.
