Free Claude skill

The model choice skill

Describe the job and the data, and Claude walks you through whether a hosted model is enough or you need an open-weight or custom model, and why.

  • Asks about the data, the volume, the privacy rules and the country it must stay in
  • Weighs hosted, open-weight and fine-tuned options honestly
  • Writes a one-page recommendation you can take to your board

A written recommendation in fifteen minutes.

One email with the skill attached. Nothing else unless you reply.

Made by Sentry AI

We are an AI consulting and development agency for New Zealand and Australia. When a hosted model is not the right answer: models you run, on hardware you choose, in the country you choose. Research today, not a service we sell.
