Every Mesa user has an allocation of model usage. Keeping an eye on it helps you pace your work and save higher-capability models for the tasks that need them. ## Check your usage Click your email in the bottom-left corner of the home page to see how much usage you've consumed and how much you have left.

## How usage works Usage is shown as two values: * **Daily usage** tells you what you've used recently. * **Weekly usage** helps you plan across a longer stretch of work. Your allocation is set by your organization's **Owner**, who can view and adjust each member's usage from the Organization page. If you're unsure how usage is calculated for your account, ask your Owner. ## Make the most of your allocation * Use lighter models like **Claude Sonnet 5**, **GPT 5.4 Mini**, or **Gemini 3.5 Flash** for short questions and simple tasks. * Reserve higher-capability models like **Claude Opus 4.8** and **GPT 5.5** for research, drafting, and complex work. * Save **Deep Research** effort for tasks that involve large context, many files, or a deliverable-style output. * Check your usage before starting a long work session so you're not surprised mid-task. [Models](/models) compares every model and effort level so you can match each task to the right amount of usage. ## Related articles Pick models and effort levels that fit your task and usage budget.
