OpenAI pushes ChatGPT toward autonomous work with GPT-5.5

OpenAI launched GPT-5.5 in ChatGPT and Codex for paid users, including Plus, Pro, Business, and Enterprise plans.

The model is better at planning, coding, research, prompt interpretation, and multi-step task execution with less user guidance.

OpenAI also says GPT-5.5 improves efficiency, reliability, and self-checking for more dependable work outputs.

The update points to OpenAI’s shift from chat-first assistance toward autonomous AI that can execute real tasks end to end.

That could boost productivity for developers and businesses while increasing competition in enterprise AI.
