OpenAI has launched its latest GPT-5.1 model for all users at the same price as the GPT-5 model. OpenAI CEO Sam Altman said, “We are also releasing gpt-5.1-codex and gpt-5.1-codex-mini in the API, specialised for long-running coding tasks. Prompt caching now lasts up to 24 hours!” GPT-5.1 in the API offers a balance of intelligence and speed for agentic and coding tasks. The model adapts its thinking time based on task complexity, making it faster and more token-efficient for everyday use. It also includes a “no reasoning” mode for instant responses when deep analysis isn’t needed. ChatGPT Group Chat: OpenAI Rolls Out New Chat Feature in Pilot Across 4 Countries, Allowing Users To Collaborate, Continue Same Conversation.
