OpenAI releases GPT-5.5, claiming better coding ability and ability to handle messy multi-step tasks without step-by-step instructions

OpenAI announced GPT-5.5, a new version of its AI model released just one month after GPT-5.4. The company says it excels at writing and debugging code, doing research, creating spreadsheets and documents, and switching between different tools.

Unlike previous AI models that require users to carefully guide each step, GPT-5.5 can take a vague or complex multi-part task (like 'analyze competitor pricing, update our price sheet, and draft a summary email') and plan the steps itself, use the right tools, check its own work, and recover from confusion—without constant human direction.

For software developers, this could cut the time spent writing and fixing code. For business professionals managing complex workflows across multiple tools (email, spreadsheets, documents), this reduces manual juggling between applications and the need to precisely specify each step.
