gemma-2-2b optimized for Arm-based Edge Linux

gemma-2-2b text generation model, optimized with INT8 quantization and exported as an ExecuTorch program for the XNNPACK CPU backend on Arm-based platforms.

This model was optimized using Arm AI Model Optimizer .

Summary

This repository contains an optimized version of google/gemma-2-2b for text generation. The model is provided as an ExecuTorch .pte file using the XNNPACK delegate, targeting Edge Linux systems. Precision: INT8 weights (quantization details not recorded in metadata).

Optimization approach

Intended use

This model is intended for developers evaluating text generation workloads on Arm-based Edge Linux platforms. It is suitable as a reference implementation for benchmarking, prototyping, and integration exploration.

Limitations

• Performance depends on the target device, runtime version, backend support, memory configuration, and system load.
• Quality was measured on HellaSwag only. Task-level behavior on other benchmarks was not evaluated.
• This repository is not a replacement for the original model documentation.

About this version

Original Model: google/gemma-2-2b by Google - Repository

Optimization/conversion: INT8 quantization and ExecuTorch .pte export with XNNPACK backend support for execution on Arm-based platforms.

Converted/optimized by: Nota AI, using Arm AI Model Optimizer

License: The Original Model and the Optimized Model are subject to Gemma Terms of Use .

This repository contains a converted or optimized version of the Original Model (the "Optimized Model"). The Original Model has been converted or optimized as described above for execution on Arm-based platforms.

No retraining or fine-tuning of the Original Model was performed as part of the conversion or optimization. The conversion or optimization was not intended to change the Original Model's behavior or intended use.
