I burned though $50 on OpenRouter in three days, this is with selective model routing based on tasks/strict AGENTS.md. A Claude 20x sub running Sonnet 5/Opus 5 and light Fable usage gets me through the month. It wasn't even close even though I wish it were.
Damn that's crazy. I put in $10 on the 5th of August and still have $1.99 left today, the 18th. I use Deepseek Flash almost exclusively.
