OpenAI continues naming chaos despite CEO acknowledging the habit
On Monday, OpenAI announced the GPT-4.1 model family, its newest series of AI language models that brings a 1 million token context window to OpenAI for the first time and continues a long tradition of very confusing AI model names. Three confusing new names, in fact: GPT4.1, GPT4.1 mini, and GPT4.1 nano.
According to OpenAI, these models outperform GPT-4o in several key areas. But in an unusual move, GPT-4.1 will only be available through the developer API, not in the consumer ChatGPT interface where most people interact with OpenAI's technology.
The 1 million token context window-essentially the amount of text the AI can process at once-allows these models to ingest roughly 3,000 pages of text in a single conversation. This puts OpenAI's context windows on par with Google's Gemini models, which have offered similar extended context capabilities for some time.
