# Usage and limits

## Understand your usage

**Usage** combines Codex, Claude Code, and Grok Build session history from your connected
environments. It shows token use, cache savings, model breakdowns, and estimated API-equivalent
cost. These estimates are not your subscription bill.

Totals depend on the history available on each server. Grok turns without a saved completed-turn
record are missing from the totals.

On web and desktop, use the environment dropdown to filter costs, tokens, and limits. All
environments are selected by default. The dropdown shows which environments are still scanning;
results appear as each one responds.

If recent work is missing or a new model shows no cost, refresh to rescan session history and
update model pricing.

## Set custom model prices

On web or desktop, open the environment dropdown on **Usage**, then choose **Model prices** to add,
edit, or reset a model's estimated price. **Apply to** starts with your current Usage filter;
choose all environments or select individual destinations. Enter the exact model ID and USD
rates per million input and output tokens. You can enter any model ID, including models
without public pricing.

Cache read and cache write rates are optional and use the input rate when blank. Enter `0` for
tokens that are free. Saved prices replace automatic pricing for all of that environment's
history and are shared with clients connected to it. When environments have different prices,
cells show **Mixed**. Edit rates directly in the table, then choose **Save changes** to apply all
edited rows. Untouched cells keep each environment's rate. Select one environment to inspect its
prices. **Reset to automatic** marks a model's override for removal when you save; you can undo
it before saving.

Each destination reports whether the change saved. Offline or unavailable environments are
marked **Not saved**. Reconnect them and choose **Retry failed saves** to finish the same change
without writing again to environments that already saved. Changes are not queued after you close
the dialog.

## Track subscription limits

**Usage → Limits** shows how much quota is left in each window and when it resets, for Codex and
Claude subscriptions. For windows with timing data, each bar also marks how much of the window is
left, so you can judge your pace before the next reset.

If a window looks stale, refresh Limits to re-check every provider and hub.

Pick `/usage-limits` from the composer's command menu, or send it as a message, to check the
current model's limits without leaving the conversation. The result opens above the composer and
closes when you dismiss it or send your next message. It uses the same snapshot as **Usage → Limits**, so it does not run the agent or refresh
anything. The command is offered only for providers that appear under **Usage → Limits**.

API-key accounts may not report subscription limits. This also applies to Claude connections
using a proxy through `ANTHROPIC_AUTH_TOKEN`.

## Connect a CLIProxyAPI hub

To see pooled accounts, open **Settings → Providers → Usage providers → Add hub**. Choose the
environment that will connect to the hub and enter its URL and management key.

The accounts appear under **Usage → Limits**. This connection supplies usage information; configure
the provider separately to send agent requests through the hub. Remove the hub from the same
settings section when you no longer need it.
