Summary

The creator set up Hermes Agent to alert him when his model credits run out. While waiting for his Grok quota to reset, he switches the agent's backend to Codex. It's a short example of handling usage limits with alerts and a fallback provider.

Key points

• Have your agent send you an alert when API or subscription credits run out.
• Keep a second model provider ready (here Codex) for when the main one (Grok) hits its limit.
• Hermes Agent can switch between model backends, so work continues while the main quota resets.
