NTP (Next Token Prediction) transforms complex multimedia data into simple sequential tokens for AI processing
This paper introduces Next Token Prediction (NTP) as a unified framework for processing multiple types of data like images, audio, and text, transforming them into sequential tokens for AI models to understand and generate.

Original Problem 🤔:
→ Current AI systems struggle to handle different types of data (text, images, audio) in a unified way, requiring separate models and approaches for each modality
-----
Solution in this Paper 🔧:
→ Introduces a framework that converts all types of data into tokens that can be processed sequentially
→ Uses two main tokenization approaches: discrete (converting data into fixed vocabulary) and continuous (preserving data's natural form)
→ Employs a transformer-based architecture that can both understand and generate multimodal content
→ Implements specialized training objectives for different types of data while maintaining a single unified model
-----
Key Insights 💡:
→ Multimodal data can be effectively processed using the same next-token prediction approach used in language models
→ Two distinct model architectures emerge: compositional (using external encoders/decoders) and unified (integrated approach)
→ Continuous tokenization better preserves information but is harder to process, while discrete tokenization is more efficient but loses some detail
-----
Results 📊:
→ Successfully demonstrates unified processing of text, images, audio, and video in a single framework
→ Shows comparable or better performance than specialized models in tasks like visual question answering and audio generation
→ Achieves efficient scaling with increasing model size and data volume
