News Summary

OpenAI has introduced the GPT-4.1 model family, which includes variations such as GPT-4.1 mini and GPT-4.1 nano. These new models feature a 1 million token context window, allowing them to process approximately 3,000 pages of text in a single conversation. This enhancement matches the context capabilities of Google’s Gemini models. However, the GPT-4.1 will only be available through the developer API, unlike its predecessors. OpenAI plans to retire the GPT-4.5 Preview model from the API by July 2025, although it will remain in the ChatGPT interface. The naming of OpenAI’s models has been a point of confusion, acknowledged by CEO Sam Altman, who aims for future consolidation with the anticipated GPT-5 release.
