GPT-5.6 is now the preferred model in Microsoft 365 Copilot

OpenAI is releasing its latest model, GPT-5.6, to a global audience following the lifting of a federal testing mandate. The launch coincides with the debut of ChatGPT Work, an agent-based service that can automate complex tasks across third-party platforms like Slack and Salesforce. This move signals a shift toward autonomous AI assistants in enterprise environments. Because federal regulatory frameworks for these advanced models remain undefined, this rollout serves as a significant test case for how developers balance rapid product expansion with safety oversight.
