OpenAI launches GPT-4.5 with improved writing and programming abilities, Sam Altman says it ‘feels like a person’
OpenAI has launched its biggest and 'best' basic model to date, GPT-4.5. The Microsoft-backed AI startup claims that compared to previous models, GPT 4.5 improves on the ability to recognise patterns, make connections and generate creative insights without the need for reasoning skills. i have had several moments where i've sat back in my chair and been astonished at getting actually good advice from an AI.” While GPT 4.5 isn't a reasoning model like the o3 Mini or DeepSeek R1, Altman says there's a "magic" to it that he hasn't seen before. OpenAI says GPT 4.5 has a broader knowledge base and improved ability to track user intent, along with a higher EQ or emotional quotient. This year alone, OpenAI has rolled out its o3 Mini reasoning model, launched an AI agent to help with workflows called Deep Research, and now the introduction of GPT 4.5.
