 ## Multihost development
 There are three patterns for running MaxText with more than one host.
 
-1. [GKE, recommended] [Running Maxtext with xpk](../Run_MaxText_via_xpk.md) - Quick Experimentation and Production support
-2. [GCE] [Running Maxtext with Multihost Jobs](Run_MaxText_via_multihost_job.md) - Long Running Production Jobs with Queued Resources
-3. [GCE] [Running Maxtext with Multihost Runner](Run_MaxText_via_multihost_runner.md) -  Fast experiments via multiple ssh connections.
