Never tried OpenCode Go so I am interested. How does their pricing compare to paying DeepSeek directly, by the way?

They have flat fees, so it's the best deal around by far. Basically for $5 first month then $10/mo after that. If you're doing tons of heavy work, it struggles because they throttle the model inference and for good reason. I mean it's cheap! But if you want a place to try models for nearly nothing and aren't doing 6 sessions in parallel it works fine.
