Which provider? I went through 40 bucks on it on openrouter. It was not a lot of back and forth, context ended at around 300k, 15kloc output. I was using opencode, unsure if I can make the total token count visible.

OpenRouter sometimes chooses a very expensive provider. Try the floor slug or choose directly the provider. I moved to just putting 5 dollars directly on deepseek instead of going through OR.
