How GPT Technology Works
The inner workings of advanced AI systems rely on intricate processes that mimic human cognition. These systems use a combination of neural networks, training data, and advanced algorithms to generate text that feels natural and context-aware.
Neural Networks and Pre-training
At the heart of these systems are neural networks, which mimic the way the human brain processes information. During the pre-training phase, the model is exposed to vast amounts of training data from the web. This unsupervised learning phase helps the system understand patterns in language.
Tokenization breaks down input text into smaller units, such as words or subwords. For example, GPT-3 uses a vocabulary of over 45,000 tokens. This process ensures the model can handle diverse sentence structures and contexts.
Transformers and Attention Mechanisms
The transformer architecture, introduced in 2017, revolutionized AI by enabling parallel processing of entire sentences. Unlike older models like RNNs, which process text sequentially, transformers use self-attention mechanisms to weigh the importance of different words in a sentence.
For instance, in the input “dog chases cat,” the model uses self-attention to understand the relationship between “dog” and “cat.” This allows it to generate accurate output based on context.
Contextual Embeddings and Fine-tuning
After pre-training, the model undergoes fine-tuning for specialized tasks. This involves adjusting parameters to optimize performance in areas like medical Q&A or code generation. Fine-tuning ensures the system delivers precise and relevant responses.
Training these models requires immense computational power. For example, GPT-3 required 3640 petaflop-days of processing, utilizing Google TPUs and NVIDIA A100 GPU clusters. This highlights the scale of resources needed for advanced machine learning.
