Blog Link: Easy-GPT4o - reproduce GPT-4o in less than 200 lines

Easy-GPT4O opensource version: use OpenAI older API implements GPT-4o in less than 200 lines of code.

Why I start this project? This is just a toy project and a simple demo. I want to prove some ideas in this project:

• Developers can build their own GPT-4o using existing APIs. By leveraging available tools, developers can easily access the capabilities of advanced models.
• End-to-end models provide low latency but limited customization. This project explores the trade-off between latency and customization, highlighting the benefits and limitations of each approach.
• The combined power of multiple models can outperform a single multimodal model. This project demonstrates the effectiveness of a collaborative approach, leveraging the collective intelligence of various models to achieve superior results.

• Python 3.6 or higher
• OpenAI Python package (openai)
• FFmpeg (for audio extraction)

1. Clone the repository:

   git clone https://github.com/Chivier/easy-gpt4o

2. Install the required Python packages:

   pip install -r requirements.txt

3. Download and install FFmpeg from the official website: https://ffmpeg.org/

# Set your own openai api
export OPENAI_API_KEY=xxxxxxx
python main.py input_video.mp4 output_audio.mp3

Replace input_video.mp4 with the path to your input video file, and output_audio.mp3 with the desired path to save the output audio file.

• Extracts audio from a video file
• Transcribes the audio using OpenAI Whisper API
• Generates image descriptions for key frames in the video using OpenAI GPT-4 Turbo API
• Combines the audio transcription and image descriptions into a comprehensive response
• Converts the response to speech using OpenAI TTS API

• Open-source Model Replace OpenAI API
• Streaming video processing
• Use RAG store long period memory
