  "textContent": "**[Introduction]**\n\n**Microsoft 365 Copilot Declarative Agents** are being **upgraded to the** **GPT‑5.2 model**. This update improves quality and reliability for agent scenarios such as reasoning, multi‑step workflows, tool calling, structured output generation, and document analysis. As with GPT‑5.1, users can continue to choose between Auto, Quick Response, and Think Deeper modes.\n\n**[When this will happen]**\n\n**General availability (Worldwide):** Rollout will begin around mid-March 2026**** and is expected to complete by**late March 2026.**\n\n**[How this affects your organization]**\n\n_Who is affected_\n\n  * Users and builders of Microsoft 365 Copilot Declarative Agents in _all Microsoft 365 tenants_\n\n\n\nWhat will happen:\n\n  * Declarative Agents will begin using the GPT‑5.2 foundational model.\n  * Users may notice improved quality, accuracy, and formatting in responses.\n  * Some agent behaviors may vary slightly due to model differences.\n  * The update will roll out gradually; not all users will receive the new model at the same time.\n  * No admin controls are changing, and existing settings continue to apply.\n\n\n\n**[What you can do to prepare]**\n\nNo configuration changes are required. To support a smooth transition, consider the following steps:\n\n  * **Inform agent builders** that the model upgrade is rolling out.\n  * **Validate** your organization’s **most important agent workflows** (for example, top 5–10 prompts or use cases).\n  * Check that agents continue to meet expectations for accuracy, tone, and formatting.\n  * **Monitor agent behavior and submit feedback** through the thumbs up/down feature.\n    * Include**#GPT52** when reporting issues or successes.\n\n\n\n**[Compliance considerations]**\n\nNo compliance considerations identified. Review as appropriate for your organization.",
