Common questions
Which OpenAI model should I use?
Depends on the task, quality bar and budget. I'll benchmark a few on your real prompts and often mix models — a cheaper one for routine calls, a stronger one where it counts — to balance cost and quality.
Can you help cut our OpenAI bill?
Yes. I routinely lower costs with caching, prompt slimming, model tiering and smarter retrieval — usually without any drop in output quality, often with a measurable improvement.
Do you work with Azure OpenAI too?
Yes. If you're on Azure OpenAI for compliance or procurement reasons, I can build against it with the same reliability and cost practices.
