The intelligence is amazing, but for 90% of our user queries, GPT-4o-mini was already good enough. GPT-5.1 is overkill and blows up our margins. We reserve it only for the most complex tier of our application. The structured outputs (JSON mode) are rock solid now.

I fed it a 2000-line legacy codebase and asked for a refactor plan. It not only understood the architecture but wrote the migration scripts. It understands nuance and intent better than any previous model. It's finally truly useful as a senior pair programmer.

Using the API, the step up from GPT-4o is tangible. It handles multi-step logic puzzles and complex coding refactors with way fewer hallucinations. The latency is surprisingly low for the model size. It feels like it actually 'thinks' before answering. It's expensive per token, but for high-value tasks, it's the only option.
