   The error "unknown certificate verification error Failed to fetch models.dev" typically occurs in restricted network environments with corporate proxies. You may need to:

   1. Set environment variables like SSL_CERT_BUNDLE, REQUESTS_CA_BUNDLE, or NODE_EXTRA_CA_CERTS
   2. Configure your proxy settings
   3. Check your corporate firewall/certificate configuration

   Feel free to ignore if none of these address your specific case.

   Could you please walk me through the steps on Windows 10?

   Same error has been torturing me for 2 days. I know it must be the corp proxy env because the exact same operations just run well in my PC at home. But accessing Internet is impossible in the corp network, i.e., the resources including llm are all local.

   Please let me know if this problem is solved. Thanks a lot in advance.

   I have the same problem. Opencode can't access MiniMax, but it could access other models normally. I don't understand

   I uninstall the tailscale, but I didn't clear the regedit. I found deleting the configure of Tailscale from regedit will fix the problem.

    I finally succeeded. You need to disable title-agent in the file opencode.json, and then opencode won't call SmallModel during the loop.

But accessing Internet is impossible in the corp network, i.e., the resources including llm are all local.同样的错误已经折磨我两天了。我知道肯定是公司代理环境的问题，因为在我家里的电脑上，同样的操作也能正常运行。但在公司网络中无法访问互联网，也就是说，包括 llm 在内的所有资源都是本地的。

    I finally succeeded. You need to disable title-agent in the file opencode.json, and then opencode won't call SmallModel during the loop.我终于成功了。你需要在 opencode.json 文件中禁用 title-agent，这样 opencode 就不会在循环过程中调用 SmallModel。

    what is the "small model"

    ---

    To my understanding, "small_model" is a second model defined by opencode official and used in light-weight tasks such as session name generation. I tried at the beggining of debugging to configure "small_model to" be the same one as the primary model but the workflow still failed (it goes for public models anyway). Then I checked the details print and find out that agent "title" was calling "small_model" so I shut it down. Then it wroks well.

    "model": "ProviderX/ModelY",
    "small_model": "ProviderX/ModelY",
    "agent": {
    "title": {
    "disable": true
    }
    },
