OpenAI o3 is the reasoning model OpenAI unveiled in late 2024 as the successor to OpenAI o1. It moved the bar visibly higher on reasoning benchmarks while adding optimizations around Tool Use and agent workflows. Its near- or above-human results on tough tasks like ARC-AGI reignited the public AGI conversation. As a reference point in the Reasoning Models category it is now routinely benchmarked alongside DeepSeek R1 and Claude Opus.
