AI Model Selector

Do not choose a model from a leaderboard. Define the job, constraints, and failure costs first. This tool recommends a durable model profile you can test across vendors.

Use-case requirements

What does the model need to do?

Choose the closest task, then mark every constraint that materially affects production use.

Primary task

Data must stay in our environmentDeployment control or open weights are a hard requirement. Users need near-instant responsesLatency matters more than squeezing out the last increment of quality. Unit economics dominateThe workflow runs often enough that cost per successful task is critical. Inputs are unusually largeThe model must work across long documents, repositories, or histories. It must reliably use toolsStructured output, function calling, or multi-step agent behaviour is central. Errors have serious consequencesA wrong answer could create legal, financial, safety, or reputational harm.
