The AWS-Hosted option for Agentforce will use Anthropic Claude Haiku 4.5 on Amazon Bedrock later this month. It currently uses Claude Sonnet 4, which is in the Legacy state on Amazon Bedrock.
Where: This change applies to Lightning Experience in Enterprise, Performance, and Unlimited editions with Foundations or Agentforce 1 editions.
When: This change is available starting the week of May 18, 2026.
How: To select the model option for Agentforce, from Setup, in the Quick Find box, enter Audit, Analytics, and Monitoring and select Einstein Audit, Analytics, and Monitoring Setup. Choose an option in the Select the Model for Agentforce section. The model option selection applies to all Agentforce agents.
If you previously created any prompts or custom actions or subagents for Agentforce, test them after switching your model option.
If you choose the AWS-Hosted option, update custom agent actions to use Anthropic Claude Haiku 4.5 on Amazon for consistency.
To test the AWS-Hosted option in Agentforce in a sandbox before the week of May 18, contact your Salesforce account executive. Alternatively, you can configure the model for an agent in Agent Script. See Configure Models in Agent Script in the Agentforce Developer Guide.
