+            We currently offer six classes of compute instances:
 
               * `nanode` - Nanode instances are good for low-duty workloads, where performance isn't critical. **Note:** As of June 16th, 2020, Nanodes became 1 GB Linodes in the Cloud Manager, however, the API, the CLI, and billing will continue to refer to these instances as Nanodes.
               * `standard` - Standard Shared instances are good for medium-duty workloads and are a good mix of performance, resources, and price. **Note:** As of June 16th, 2020, Standard Linodes in the Cloud Manager became Shared Linodes, however, the API, the CLI, and billing will continue to refer to these instances as Standard Linodes.
               * `dedicated` - Dedicated CPU instances are good for full-duty workloads where consistent performance is important.
-              * `premium` - In addition to the features of Dedicated instances, Premium instances come equipped with the latest AMD EPYC™ CPUs, ensuring your applications are running on the latest hardware with consistently high performance.
-              * `gpu` - Linodes with dedicated NVIDIA Quadro® RTX 6000 GPUs accelerate highly specialized applications such as machine learning, AI, and video transcoding.
+              * `premium` (limited Regions) - In addition to the features of Dedicated instances, Premium instances come equipped with the latest AMD EPYC™ CPUs, ensuring your applications are running on the latest hardware with consistently high performance. Only available in [Regions](/docs/api/regions/#regions-list) with "Premium Plans" in their `capabilities`
+              * `gpu` (limited Regions) - Linodes with dedicated NVIDIA Quadro® RTX 6000 GPUs accelerate highly specialized applications such as machine learning, AI, and video transcoding. Only available in [Regions](/docs/api/regions/#regions-list) with "GPU Linodes" in their `capabilities`
               * `highmem` - High Memory instances favor RAM over other resources, and can be good for memory hungry use cases like caching and in-memory databases. All High Memory plans contain dedicated CPU cores.
