Trying DeepSeek V4 with OpenCode

Regarding my last post: While I spent plenty of thoughts on the whole implementation, most of the coding work was actually done by DeepSeek V4 Flash and Pro, and I just supervised and criticized it. While I mainly used Amp Free in the last few months, Amp Free is dead. The daily free usage was cut to 5 dollars, and with the expensive prices of Claude Opus, that’s used up pretty fast. GitHub Copilot (Student) isn’t also really useful anymore. So I discovered OpenCode. There are free models, but it can also be connected with other providers (like Cortects) or with their Go subscription (10 dollars per month; the first month is 5 dollars). I tried it with Cortects (which is quietly adding many features to become a viable OpenRouter alternative) but also spent 5 dollars on the OpenCode Go subscription to try OpenCode without fear of spending endless money on tokens. And given DeekSeek V4 (especially Flash) is so cheap compared to the other frontier models, it’s remarkable how capable it…
