1. Switch to extra usage, which can be increased on the Claude usage page: https://claude.ai/settings/usage
2. Logout and Switch to API tokens (using the ANTHROPIC_API_KEY environment variable) instead of a Claude Pro subscription. Credits can be increased on the Anthropic API console page: https://platform.claude.com/settings/keys
3. Add a second 20$/month account if this happens frequently, before considering a Max account.
4. Not a native option: If you have a ChatGPT Plus or Pro account, Codex is surprisingly just as good and comes with a much higher quota.
This completely depends on the domain, as always. Each of the big 3 have their strengths and weaknesses.
