Choosing a model

Vaulter lets you choose which AI model powers your build, or pick for you. You will find the model picker near the chat in the build workspace.

Auto and Manual

The picker has two settings:

• Auto. Vaulter picks the model for each step. This is the default, and the right choice for most people.
• Manual. You choose which model runs your requests, and it stays chosen until you change it.

The models

In Manual mode there are three Vaulter agents, ordered from fastest to most capable:

• Vaulter Mini. Fast and cost-efficient. Great for small, well-defined changes: copy edits, styling tweaks, simple additions. Uses the fewest tokens.
• Vaulter Pro. Balanced performance. The all-rounder that handles the large majority of requests well. This is the default.
• Vaulter Max. Maximum intelligence. The deepest model, for genuinely complex, multi-step work: intricate features, tricky logic, and large changes that span many parts of the app. Available on paid plans.

On the free plan, Vaulter Max shows with a lock; upgrading unlocks it.

Which to pick

• Leave it on Auto unless you have a reason not to.
• Drop to Mini when you are firing off lots of small changes and want the tightest loop at the lowest token cost.
• Reach for Max when a task feels genuinely complex, or when a request did not land the way you wanted and you want a more careful attempt before rephrasing.

Models and tokens

Deeper models use more tokens per request than faster ones, and your plan includes a monthly token allowance. If you are watching your usage, Mini stretches your allowance furthest; Max spends it fastest but wastes fewer attempts on hard problems. See Plans and pricing.

One more place models matter: Plan mode always runs on the most capable model, regardless of your picker setting, because planning quality pays for itself.
