States OpenAI[1] released o3 and o4-mini on April 16, 2025.
TechCrunch report dated April 16, 2025 on the o3 and o4-mini launch.
Archived copy of OpenAI's[1] o3 and o4-mini announcement, which says o3 "sets a new SOTA on benchmarks including Codeforces, SWE-bench ... and MMMU", makes "20 percent fewer major errors than OpenAI o1", and o4-mini "achieves 99.5% pass@1" on AIME 2025 with Python.

OpenAI says that o3 achieves state-of-the-art performance on SWE-bench verified (without custom scaffolding), a test measuring coding abilities, scoring 69.1%.
o3 is $10/million input and $40/million for output, with a 75% discount on cached input tokens, 200,000 token context window, 100,000 max output tokens and a May 31st 2024 training cut-off (same as the GPT-4.1 models).
So, if you ignore the headlines and drown out the hype, which is to be honest good advice for all times in life, o3 represents genuine progress. Well done to OpenAI.
