[Bug Report] Abnormal Credit Consumption on OpenCode Go (42% used in ~4 hours)

Description

I am testing the new "OpenCode Go" provider on my account. I noticed a severe issue where the credits are being deducted at an abnormal rate.
According to the usage dashboard, 42%​ of my total monthly limit was consumed in just 4 hours and 27 minutes. This implies that the system is using approximately 10% of my total quota per hour, which seems like a bug or a miscalculation, as normal model usage should not deplete the quota this quickly.
Additionally, the usage stats show strange reset timers:
Rolling Usage:​ Resets in 4 hours 27 min (42%)
Weekly Usage:​ Resets in 4 days 13 hours (17%)
Monthly Usage:​ Resets in 30 days 23 hours (8%)
The short reset time for "Rolling Usage" alongside the massive percentage drop suggests a potential system error. I only performed minimal testing, yet the costs accumulated to 1.3 very rapidly.
