OpenAI brings its GPT-4.1 models to ChatGPT

OpenAI has upgraded its AI models with enhanced versions of GPT-4.1 in ChatGPT and introduced a free GPT-4.1 mini for paying users, while discontinuing the older GPT-4.0 mini to address transparency concerns about safety. The company has also increased internal evaluations on AI model safety through a new hub and is nearing the acquisition of Windsurf, with updates to tools like Gemini for better GitHub integration.
