OpenAI unveils its new GPT-4.5 large language model

OpenAI unveiled GPT-4.5, its most advanced chat model to date, trained with significantly increased computing power compared to its predecessor. This new model exhibits improved natural language generation, better general world understanding, and enhanced writing and coding capabilities. Hallucinations are reduced, and the model displays increased emotional intelligence in its responses. Improvements are subtle yet meaningful across various tasks, representing a general enhancement rather than specific skill boosts. The model's performance supports the idea that scaling model size and computing power yields significant gains, although this claim is debated. Training costs are substantial, potentially reaching a billion dollars. GPT-4.5 is initially available as a research preview to select users and developers. Wider access will be granted to ChatGPT Plus and Team users shortly. The release signifies OpenAI's continued progress in large language model development.
