OpenAI drop the price of o3 by 80%. That's good news for people using the API. At this point, it really is very competitive with everyone trying to beat everyone else.

OpenAI o3 is the company's most powerful reasoning model that pushes the frontier across coding, math, science, visual perception, and more. It sets a new SOTA on benchmarks including Codeforces, SWE-bench (without building a custom model-specific scaffold), and MMMU. It’s ideal for complex queries requiring multi-faceted analysis and whose answers may not be immediately obvious. It performs especially strongly at visual tasks like analyzing images, charts, and graphics. In evaluations by external experts, o3 makes 20 percent fewer major errors than OpenAI o1 on difficult, real-world tasks — especially excelling in areas like programming, business/consulting, and creative ideation. Early testers highlighted its analytical rigor as a thought partner and emphasized its ability to generate and critically evaluate novel hypotheses — particularly within biology, math, and engineering contexts.

Updated: OpenAI have now added o3 Pro for users that are willing to pay $200 a month.
