This tutorial demonstrates building a multimodal language tutor using Microsoft's lightweight Phi-4-multimodal model. This AI-powered application leverages text, image, and audio processing for a comprehensive language learning experience.
Key Features:
Phi-4-Multimodal Overview:
Phi-4-multimodal excels at processing text, images, and speech. Its capabilities include:
Its 128K token context length optimizes performance for real-time applications.
Step-by-Step Implementation:
1. Prerequisites:
Install necessary Python libraries:
pip install gradio transformers torch soundfile pillow flash-attn --no-build-isolation
Note: FlashAttention2 is recommended for optimal performance. If using older GPUs, consider setting _attn_implementation="eager"
during model initialization.
Import required libraries:
import gradio as gr import torch import requests import io import os import soundfile as sf from PIL import Image from transformers import AutoModelForCausalLM, AutoProcessor, GenerationConfig
2. Loading Phi-4-Multimodal:
Load the model and processor from Hugging Face:
model_path = "microsoft/Phi-4-multimodal-instruct" processor = AutoProcessor.from_pretrained(model_path, trust_remote_code=True) model = AutoModelForCausalLM.from_pretrained( model_path, device_map="cuda", torch_dtype="auto", trust_remote_code=True, _attn_implementation='flash_attention_2', ).cuda() generation_config = GenerationConfig.from_pretrained(model_path)
3. Core Functionalities:
clean_response(response, instruction_keywords)
: Removes prompt text from the model's output.process_input(file, input_type, question)
: Handles text, image, and audio inputs, generating responses using the Phi-4-multimodal model. This function manages the input processing, model inference, and response cleaning for each modality.process_text_translate(text, target_language)
and process_text_grammar(text)
: Specific functions for translation and grammar correction, respectively, leveraging process_input
.4. Gradio Interface:
A Gradio interface provides a user-friendly way to interact with the model. The interface is structured with tabs for text, image, and audio processing, each with appropriate input fields (text boxes, image upload, audio upload) and output displays. Buttons trigger the relevant processing functions.
5. Testing and Results:
The tutorial includes example outputs demonstrating the model's capabilities in translation, grammar correction, image text extraction, and audio transcription/translation. These examples showcase the functionality of each module within the application.
Conclusion:
This tutorial provides a practical guide to building a robust multimodal language tutor using Phi-4-multimodal. The application's versatility and real-time capabilities highlight the potential of multimodal AI in enhancing language learning.
