 Note that groupsize less than 128 was not enabled, since such model were still too large. This is because our current efforts have focused on enabling FP32 and support for FP16 is under way. What this implies for model size is that 1) embedding table is in FP32 and 2) quantized weights scales are FP32.
 
+## Enablement 
+
+We have verified running Llama 2 7B [mobile applications](#step-6-build-mobile-apps) efficiently on select devices including the iPhone 15 Pro, iPhone 15 Pro Max, Samsung Galaxy S22 and S24, and One Plus 12.

 ## Performance
 
-Performance was measured on Samsung Galaxy S22, S24, One Plus 12 and iPhone 15 max Pro. Measurement performance is in terms of tokens/second.
+Performance was measured on the Samsung Galaxy S22, S24, and One Plus 12 devices. The performance measurement is expressed in terms of tokens per second using an [adb binary-based approach](#step-5-run-benchmark-on).
 
 |Device  | Groupwise 4-bit (128) | Groupwise 4-bit (256)
 |--------| ---------------------- | ---------------
-|Galaxy S22*  | 8.15 tokens/second | 8.3 tokens/second |
