| | # Llama-v3.1-8B-Instruct: Optimized for Qualcomm Devices |
| |
|
| | Llama 3 is a family of LLMs. The model is quantized to w4a16 (4-bit weights and 16-bit activations) and part of the model is quantized to w8a16 (8-bit weights and 16-bit activations) making it suitable for on-device deployment. For Prompt and output length specified below, the time to first token is Llama-PromptProcessor-Quantized's latency and average time per addition token is Llama-TokenGenerator-Quantized's latency. |
| |
|
| | This is based on the implementation of Llama-v3.1-8B-Instruct found [here](https://github.com/meta-llama/llama3/tree/main). |
| | This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/qai_hub_models/models/llama_v3_1_8b_instruct) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary). |
| |
|
| | Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device. |
| |
|
| | ## Deploying Llama 3.1 on-device |
| |
|
| | Please follow the [LLM on-device deployment](https://github.com/quic/ai-hub-apps/tree/main/tutorials/llm_on_genie) tutorial. |
| |
|
| | ## Getting Started |
| | Due to licensing restrictions, we cannot distribute pre-exported model assets for this model. |
| | Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/qai_hub_models/models/llama_v3_1_8b_instruct) Python library to compile and export the model with your own: |
| | - Custom weights (e.g., fine-tuned checkpoints) |
| | - Custom input shapes |
| | - Target device and runtime configurations |
| |
|
| | See our repository for [Llama-v3.1-8B-Instruct on GitHub](https://github.com/qualcomm/ai-hub-models/blob/main/qai_hub_models/models/llama_v3_1_8b_instruct) for usage instructions. |

|
| | ## Model Details |
| |
|
| | **Model Type:** Model_use_case.text_generation |
| | |
| | **Model Stats:** |
| | - Input sequence length for Prompt Processor: 128 |
| | - Maximum context length: 4096 |
| | - Quantization Type: w4a16 + w8a16 (few layers) |
| | - Language(s) supported: English. |
| | - TTFT: Time To First Token is the time it takes to generate the first response token. This is expressed as a range because it varies based on the length of the prompt. The lower bound is for a short prompt (up to 128 tokens, i.e., one iteration of the prompt processor) and the upper bound is for a prompt using the full context length (4096 tokens). |
| | - Response Rate: Rate of response generation after the first response token. |
| | |
