I bought it through OpenRouter and used it with Pi agent.
The model was good, but there appeared to be a pricing glitch or something, because it burned through $50 in under an hour on pretty trivial stuff.
Pi agent claimed it only used like $1. OpenRouter claimed differently and said I used all $50.
I use Openrouter for everything except Deepseek. For Deepseek I use their API directly.
I use it from pi.dev as well through the OpenCode Go $10 subscription ($5 first month).
Used more than 20M tokens at a cost of ~$20 (up to $60 is included in the $5 plan) Out of which deepseek pro had ~200 messages which is around 1.5M tokens (10+M cached)
You can check the logs in OpenRouter and see which providers it used and how many tokens you used.
