Who do you buy DeepSeek from?
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 can highly recommend OpenCode Go.
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 directly from https://platform.deepseek.com/
I use it through OpenRouter via Kilo Code VS Code extension.
You can check the logs in OpenRouter and see which providers it used and how many tokens you used.
sounds like a caching issue, and maybe other issues too
Why do you even need openrouter as a middle man?
Check cache hits in your logs. You can use Openrouter or pi config to pin providers with best cache hit rates (or disable ones with the worst).
I use Openrouter for everything except Deepseek. For Deepseek I use their API directly.
