Subscription plans

A flat fee buys a generous token quota for the period. When it runs out, buy another plan or switch to pay-as-you-go.

Loading plans…

💡 Quota counts billable tokens: cache-miss input & output 1:1, cached input only 1/50 (it's ~50× cheaper). A typical 60M-token cached day uses just ~1.2M of quota. Plans stack: buy another to add quota + time.

Recharge bonus 🎁

New users get extra credit on top-up.

Pay-as-you-go pricing

Only pay for tokens used, in USD. Three-tier billing passed through (DeepSeek & Qwen): cached input is dramatically cheaper. /v1/models
