GPT-4.5 is out! We've been testing it for a few days @every and, honestly...it’s not going to blow your mind, but it might befriend you. It's more like a personality, communication, and creativity upgrade than a huge intelligence leap. It's like OpenAI is pivoting its base model from "bland assistant" to "AI bestie." What it does do well: - OpenAI says it scores 64% on SimpleQA (double GPT-4's score) - Much better writing with cleaner, better structured, more human-like prose - Genuinely warmer and more emotionally intelligent (gave me some good advice!) - Less robotic, more opinionated responses We ran personality tests and 4.5 is more extroverted, agreeable, and less neurotic than 4o. The trade-off? It's sometimes worse at following instructions and because it's less sycophantic and more creative. It also hallucinated in our testing. I didn't love it day one, but after more use it’s growing on me
