OpenAI unveiled its GPT-4.1 model family, introducing three new variations with a substantial 1 million token context window, significantly expanding the amount of text processed in one go. This advancement enhances developer AI capabilities but remains exclusive to the API platform, not accessible through the popular ChatGPT interface. In addition, OpenAI will phase out the GPT-4.5 Preview model by July 2025, enhancing its commitment to streamline model offerings amidst ongoing confusion over product names. The company aims for future consolidation under GPT-5 to simplify branding.
"These new models are designed for developers and outperform the previous versions in key areas, yet will only be available through API access, not in ChatGPT."
"OpenAI is introducing a 1 million token context window, allowing the AI to process about 3,000 pages of text in a single conversation, similar to capabilities in Google's Gemini models."
