# Baichuan-7B: Optimized for Mobile Deployment
## Large language model achieving state-of-the-art performance on Chinese and English language benchmarks

Baichuan-7B is a family of LLMs. It achieves the state-of-the-art performance of its size on standard Chinese and English authoritative benchmarks (C-EVAL/MMLU). 4-bit weights and 16-bit activations making it suitable for on-device The model is quantized to 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-KVCache-Quantized's latency.

This is based on the implementation of Baichuan-7B found
[here](https://github.com/baichuan-inc/Baichuan-7B/). More details on model performance
accross various devices, can be found [here](https://aihub.qualcomm.com/models/baichuan_7b_quantized).
