You're sort of glossing over the part where this can now be leveraged as a cost-efficient agentic model that performs better than o3. Nobody used o3 for sw agent tasks due to costs and speed, and this now substantially seems to both improve on o3 AND be significantly cheaper than Claude.
o3's cost was sliced by 80% a month or so ago and is also cheaper than Claude (the output is even cheaper than GPT-5). It seems more cost efficient but not by much.
O3 is fantastic at coding tasks, until today it was smartest model in existence. But it works only in few shot conversational scenarios, it's not good at agentic harnesses.
