mimo-v2.5-pro blocked by cross-border isolation policy on EU (Amsterdam) endpoint

[johannes-engler-mw]

Description

Requests to mimo-v2.5-pro via the EU endpoint (token-plan-ams.xiaomimimo.com/anthropic) are intermittently rejected
with:

API Error: 451 451 Unavailable For Legal Reasons

In the debug logs I see this:

  Access denied due to cross-border isolation policy.
  Please ask the service owner to enable "Allow Cross-border Access" in MiFE.

This only affects the pro model — mimo-v2.5-flash and other models on the same endpoint work without issues.

Environment

• Endpoint: token-plan-ams.xiaomimimo.com/anthropic
• Model: mimo-v2.5-pro
• Client: Claude Code (Anthropic CLI)
• Region: EU

Behavior

• The error is intermittent — retrying immediately usually succeeds.
• The same pattern has been reported on the SGP endpoint in Intermittent "model not found or no access" errors when using mimo-v2.5-pro through Claude Code #41.

Questions

1. Is cross-border access intentionally restricted for the pro model on the EU endpoint?
2. Is there a recommended retry strategy or alternative endpoint for EU users?
3. Will this be resolved, or is the pro model only supported from certain regions?
