# MAX

> The most capable models, for the most complex tasks

MAX allows Summer Engine to select the most capable models for you, recommended for the most complex tasks. It maxes out context windows and tool calls, and it is billed at the API pricing of the models it picks.

MAX is available on all paid plans. In the model selector it appears as **MAX**, next to Auto.

## When to Use MAX

* Long agentic tasks that span many files.
* Complex refactors and architecture work.
* Hard reasoning problems where quality matters more than speed or cost.

## When Auto Is Enough

For everyday tasks — small features, quick edits, questions about your project — [Auto](/auto-mode/auto) is faster and cheaper.

## Picking a Specific Model

If you want a specific model rather than letting MAX pick, see [Models](/auto-mode/models).

<Info>
  MAX routing is opaque on purpose: the underlying model may change as new flagship models ship. If you need a specific model, pick it directly from the selector.
