[Read the post](https://demiliani.com/2026/05/10/dynamics-365-business-central-agents-announcing-new-updates/) · Stefano Demiliani (Stefano Demiliani, MVP) · 2026-05-10 · 174 words · tier community · reviewed (checked by Opus)

> Business Central update 28.1 enables deploying custom agents to production environments and introduces GPT-5.3-chat as the default model for Copilot, rolling out from May to June. A new UI setting lets users view and select models for custom agents, with programmatic control via AL methods coming soon.

## Key points

- Starting with update 28.1, custom Business Central agents can be deployed to production environments
- GPT-5.3-chat becomes the default Copilot model, rolling out gradually across regions between May and June
- A new setting on the Agents page shows which model each custom agent uses and lets you pick another
- An AL method to set the model from code is announced but not yet available
- Existing agents switch to the new model on their own, but the author advises testing them once the model selector appears

## Quotes

- "Dynamics 365 Business Central update 28.1 will allow you to deploy your own Business Central agents to production environments." (This marks a key milestone for agent capabilities, moving from preview to production-ready custom agents.)
