GPT (Generative Pre-trained Transformer)
OpenAI's family of language models that generate human-like text. GPT-4 is currently the most capable version, excelling at reasoning, coding, and analysis.
In-Depth Explanation
GPT (Generative Pre-trained Transformer) is OpenAI's series of language models that have defined the current AI era. The name describes three key aspects: they generate text, they're pre-trained on vast data before deployment, and they use transformer architecture.
Evolution of GPT:
- GPT-1 (2018): Proved the pre-training approach works
- GPT-2 (2019): Demonstrated coherent long-form text generation
- GPT-3 (2020): Revealed emergent capabilities and few-shot learning
- GPT-3.5/ChatGPT (2022): Made AI conversational and accessible
- GPT-4 (2023): Multimodal, stronger reasoning, longer context
- GPT-4o (2024): Optimised for speed and multimodal interaction
Key capabilities include:
- Natural language understanding and generation
- Code writing, review, and explanation
- Analysis and reasoning
- Translation and summarisation
- Following complex multi-step instructions
GPT models set the benchmark that other models are compared against. Their API is the most widely-used for AI application development.
Business Context
GPT models set the standard for general-purpose AI capabilities. GPT-4 is ideal for complex tasks; GPT-3.5 offers cost-effective high-volume processing.
