Geo-Aware Routing for Agentforce Coworker

Agentforce Coworker follows the same geo-aware routing rules as the broader Agentforce platform for AI inference - the process of running a query through an AI model to generate a response.

Two conditions can route Agentforce Coworker’s inference to US-based infrastructure:

Your region doesn’t yet have a local deployment for a given model.
A regional outage or capacity event triggers an automatic fallback.

To disable automatic rerouting to the US for supported models, see Disabling Model Provider Region Fallback at the end of this page.

Models and Their Geo-Aware Routing

Agentforce Coworker uses these model components when searching and generating answers. The Routing column shows where each model’s requests go when no local deployment exists or when a fallback triggers. To disable automatic rerouting to the US, see Disabling Model Provider Region Fallback.

Model	Model ID	Provider	Role in Coworker	Routing
Claude Haiku 4.5	BedrockAnthropicClaude45Haiku	Anthropic on AWS Bedrock	Classifies and routes queries internally within Coworker	See Geo-Aware Routing for Anthropic
Claude Sonnet 4.6	BedrockAnthropicClaude46Sonnet	Anthropic on AWS Bedrock	Synthesizes answers	See Geo-Aware Routing for Anthropic (see Note 1)
Amazon Nova Micro	amazon.nova-micro-v1:0	Anthropic on AWS Bedrock	Improves search ranking	Only used in regions that have this model available locally. See Geo-Aware Routing for Anthropic (see Note 2)

Note 1: The Geo-Aware Routing for Anthropic doc only mentions Claude Haiku 4.5. Claude Sonnet 4.6 and Amazon Nova Micro are also Anthropic models on AWS Bedrock and route the same way as Claude Haiku 4.5.
Note 2: For regions that do not have Amazon Nova Micro being served locally, this model isn’t used.

Disable Model Provider Region Fallback

The Turn Off Model Provider Region Fallback toggle prevents AI requests from being routed to the US when in-region processing is unavailable. When turned on, the feature disables US fallback for Anthropic models only.

Claude Haiku 4.5 and Sonnet 4.6 aren’t available in-region on AWS in Brazil, India, Israel, Korea, Singapore, and Switzerland. Disabling provider region fallback causes requests from those regions to fail. In any region, if both in-region endpoints are overloaded, requests return an error instead of routing to a secondary region. For compliance questions, contact your Salesforce account executive.
