Thank you for letting me know. I've been working on my fork, and I'll be posting another PR here soon. You can download the source code from my main branch at https://github.com/luanweslley77/opencode-qwencode-auth, take the directory and replace ~/.config/opencode/node_modules/opencode-qwencode-auth with my code. It's also necessary to replace ~/.cache/opencode/node_modules/opencode-qwencode-auth. This is working well for me. If you encounter any problems, initially delete the file ~/.qwen/oauth_creds.json.

I don't think Qwen has 2000 req/day. The official docs say 1000 req/day here: https://qwenlm.github.io/qwen-code-docs/en/users/configuration/auth/

Cost & quota: free, with a quota of 60 requests/minute and 1**,000 requests/day**.
