Choosing Your AI Model: It's About Cost and Control, Not Just Raw Power

Ignore raw power when picking AI models; focus on cost and control. For builders like us, raw power isn't the only metric. OpenAI just released a guide on their GPT-6 family. It shows startups how to pick models, tune them, and integrate them into production. This is the practical side of building.

You can't just pick a model that *can* do the job. You pick one that does it consistently, efficiently, and without bankrupting you. Tune reasoning. Refine prompts. Coordinate tools. These steps make a model perform predictably.

Cost matters. Simon Willison just called for hard budget caps on all AI. He's right. You can't just throw the most expensive model at every problem. Rumors say 'GPT 6.1 Sol' offers near-Astra intelligence for a fifth of the price. This shifts how you pick models.

You have to think about the actual compute cost for every single inference. Do you need the bleeding edge for a routine task, or can a smaller, cheaper model do 90% of the work for 10% of the price? My experience with Epicor Kinetic and manufacturing IT tells me you don't overspend on hardware for a job that doesn't need it. The same goes for AI.

You need to be ruthless with your model selection. Understand the trade-offs. Spend time on prompt engineering and fine-tuning so you can get away with a less expensive model. Set those budget caps early. Don't let your AI project become an open spigot for cloud compute bills. Build with your wallet in mind, not just the latest benchmark scores.
