OpenAI o3

// about OpenAI o3

o3 is OpenAI's most capable reasoning model, designed for tasks requiring extended multi-step thinking — advanced mathematics, competitive coding, scientific research, and complex analysis. It employs a 'chain of thought' process that reasons through problems before responding, achieving state-of-the-art scores on benchmarks that stump standard LLMs. Researchers, engineers, and analysts use o3 when accuracy on hard problems matters more than response speed.
