OpenAI Launches GPT-4.5 for ChatGPT--It's Huge and Compute-Intensive

GPT-4.5 is here, and OpenAI's newest generative AI model is bigger and more compute-intensive than ever--it's supposedly also better at understanding what ChatGPT users mean with their prompts. Users who want to be part of the first wave to try GPT-4.5, labeled as a research preview, will be required to pay for OpenAI's 200-a-month ChatGPT Pro subscription. Prior to this launch, 2025 has already been filled with new AI model releases. Anthropic recently put out a hybrid reasoning model for its Claude chatbot. Before that, Chinese researchers at DeepSeek rocked Silicon Valley with their release of a powerful model trained on a tiny budget, prompting OpenAI to drop a "mini" version of its reasoning model a month ago.
