# Phi-3.5-mini-instruct: Optimized for Mobile Deployment
## State-of-the-art large language model useful on a variety of language understanding and generation tasks


Phi-3.5-mini is a lightweight, state-of-the-art open model built upon datasets used for Phi-3 - synthetic data and filtered publicly available websites - with a focus on very high-quality, reasoning dense data. The model belongs to the Phi-3 model family and supports 128K token context length. The model underwent a rigorous enhancement process, incorporating both supervised fine-tuning, proximal policy optimization, and direct preference optimization to ensure precise instruction adherence and robust safety measures.

This model is an implementation of Phi-3.5-mini-instruct found [here](https://huggingface.co/microsoft/Phi-3.5-mini-instruct).

### Model Details

- **Model Type:** Model_use_case.text_generation
- **Model Stats:**
  - Input sequence length for Prompt Processor: 128
  - Context length: 4096
  - Number of parameters: 3.8B
  - Precision: w4a16 + w8a16 (few layers)
  - Num of key-value heads: 8
  - Information about the model parts: Prompt Processor and Token Generator are split into 4 parts each. Each corresponding Prompt Processor and Token Generator part share weights.
  - Prompt processor model size: 2.16 GB
  - Token generator model size: 2.16 GB
  - Use: Initiate conversation with prompt-processor and then token generator for subsequent iterations.
  - Supported languages: English, Arabic, Chinese, Dutch, French, German, Italian, Russian, Spanish, Ukranian
  - Minimum QNN SDK version required: 2.28.2
  - 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.
