On November 30, the Financial Times reported that in the fiercely competitive arena of AI supremacy, OpenAI initially surged ahead, leveraging its first-mover advantage. Nevertheless, it is now encountering the most formidable pressure since ChatGPT's launch, as its rivals Google and Anthropic are swiftly closing the gap in this domain. Google's newly unveiled large language model, Gemini 3, is widely regarded as having outperformed OpenAI's GPT-5, marking a substantial leap forward in model training. In the meantime, Anthropic's recently launched Claude Opus 4.5 has soared to the top of the programming capability rankings, with a remarkable two-thirds reduction in costs. It has demonstrated outstanding performance in the enterprise market, drawing in a substantial number of corporate clients. Conversely, OpenAI is grappling with issues like escalating data center expenses, technical hurdles, and a brain drain, while its business model is also under intense scrutiny.
