GPT

GPT is a generative pre-trained language model developed and trained by OpenAI . The name stands for "Generative Pre-trained Transformer," a neural-network architecture for natural-language processing that OpenAI has iterated through multiple versions including GPT-1, GPT-2, GPT-3, GPT-3.5, GPT-4, GPT-4o, and as of August 2025, GPT-5 . OpenAI released ChatGPT—fine-tuned for dialogue—between GPT-3 and GPT-4, partly to gather test data and refine the next generation . In Chinese venture-capital coverage, GPT has been framed as a platform-level opportunity that could extend the TMT investment cycle, though some sources cautioned against over-optimism . Elsewhere's corpus notes that OpenAI's GPT-4 remained closed-source as of early 2024, while competitors such as Google's Gemini and DeepSeek's V3 and R1 models have positioned themselves against it .
