OpenAI debuts its GPT-4.1 flagship AI model

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 is now available to developers, along with two smaller model versions. That includes GPT-4.1 Mini, which, like its predecessor, is more affordable for developers to tinker with, and GPT-4.1 Nano, an even more lightweight model that OpenAI says is its “smallest, fastest, and cheapest” one yet. All three models can process up to one million tokens of context — the text, images, or videos included in a prompt. That’s far more than GPT-4o’s 128,000-token limit. “We trained GPT‑4.1 to reliably attend to information across the full 1 million context length,” OpenAI says in a post announcing the models. “We’ve also trained it to be far more reliable than GPT‑4o at noticing ...
