The New Era of AI Reasoning
OpenAI just dropped its new reasoning models, o3 and o3-mini, now open for public safety testing and research. Fun fact: they skipped "o2" to avoid trademark drama with the UK’s O2 telecom. o3-mini offers flexible speeds—low, medium, and high—with better performance at higher settings. Plus, it’s already beating its predecessor, o1, on Codeforces, a top-tier coding benchmark. Big moves in AI development!
