OpenAI launched GPT-4.5, its most advanced chat model to date, leveraging substantially more computing power than its predecessor, GPT-4o. This model provides improved human-like outputs, better writing and programming skills, and a notable reduction in hallucinations. It demonstrates enhanced emotional intelligence, as evidenced by empathetic responses to user prompts. Feedback from early users, including cofounder Andrej Karpathy, emphasizes the subtle, yet meaningful improvements across the board. Although the model's performance benefits appear modest, they suggest a significant step forward in AI capabilities, igniting discussions within the tech community about training methodologies and model scaling.
Everything is a little bit better and it's awesome, but also not exactly in ways that are trivial to point to.
[...] it is incredibly interesting and exciting as another qualitative measurement of a certain slope of capability that comes 'for free' from just pretraining a bigger model.
