Why Use MAX Subscriptions?

Instead of paying per API call, leverage the subscriptions you already have:
  • Cost Effective: Use your existing MAX subscriptions instead of pay-per-use APIs
  • Higher Limits: MAX subscriptions often have higher rate limits and priority access
  • Latest Models: Access to the newest and most capable models in each provider’s lineup
  • Consistent Experience: Same interface across different AI providers
Whether you’re building a CLI tool, web application, or any project that needs AI capabilities, @vibe-kit/auth provides a secure, scalable authentication foundation that works with your existing subscriptions.
