OpenAI expands GPT-4.1 access to ChatGPT users, replacing GPT-4o Mini for free tier

OpenAI has officially rolled out its latest artificial intelligence models, GPT-4.1 and GPT-4.1 mini, to ChatGPT users, expanding their availability beyond the company’s API for the first time. The new models, which had previously been restricted to developers through OpenAI’s programming interface, are now accessible directly within the ChatGPT platform.

In a recent announcement via its official X account, the AI research firm highlighted that the GPT-4.1 model is particularly well-suited for coding applications and complex instruction-following tasks. It is being introduced as a viable alternative to the o3 model, especially for users who prioritise technical performance and reliability.
