Thank you for reporting this issue.

Analysis:

The error message "Unknown name \"effortLevel\" at 'request.generation_config'" with type.googleapis.com/google.rpc.BadRequest indicates the request is ultimately being sent to a Google/Gemini API endpoint, not to Anthropic's API.

Your provider "CC" is configured as providerType: "claude", so the adaptive thinking override correctly injects output_config.effort: "high" and thinking.type: "adaptive" into the request body (src/lib/anthropic/provider-overrides.ts:73-75). The request body is then serialized and forwarded as-is to the provider's configured base URL (src/app/v1/_lib/proxy/forwarder.ts:1924).

The problem is that the upstream endpoint receiving this request is a Google API (Vertex AI or a gateway that proxies to Google). Google's API does not recognize output_config or effort — these are Anthropic-specific parameters. The effortLevel mentioned in the error is Google's own field name (not present anywhere in this codebase), suggesting Google's API is attempting to interpret the unknown field and failing.

Root cause:

The provider "CC" (type claude) appears to have its base URL pointing to a Google/Vertex AI endpoint or an intermediary that forwards to Google. When adaptive thinking parameters are applied (designed for Anthropic's API), they get sent to Google's API which rejects them.

Potentially affected code:

• src/lib/anthropic/provider-overrides.ts (lines 63-78) - Applies output_config.effort and thinking.type: "adaptive" for Claude providers
• src/app/v1/_lib/proxy/forwarder.ts (lines 1748-1784) - Applies Anthropic overrides based on providerType === "claude"
• src/app/v1/_lib/proxy/forwarder.ts (lines 1900-1925) - Serializes and forwards the request body to the provider URL without stripping provider-specific fields

To help diagnose further, please confirm:

• What is the base URL configured for your "CC" provider? Is it pointing to Anthropic's API (api.anthropic.com) or to a Google/Vertex AI endpoint (e.g., *googleapis.com or a third-party gateway)?
• If using a third-party gateway, does it translate between Anthropic and Google formats?

Potential workaround:

If your "CC" provider routes to a non-Anthropic upstream, disabling adaptive thinking for that provider should avoid this error, since output_config.effort will not be injected into the request body.

您好，这说明您的供应商不支持自适应思考。请暂时关闭该功能，等待供应商支持。

我是用 opencode 的， 早上我还在用 0.4.3 版本的时候，弄了一个如下的插件，是支持的，具体是这个 issue

现在升级到最新版，然后无论我移除，还是启用这个插件，也不能使用 adaptive 了

// File: ~/.opencode/plugins/adaptiveThinking.ts
export const adaptiveThinking: import("@opencode-ai/plugin").Plugin =
  async () => ({
      loader: async () => {
        return {
          fetch: async (url: RequestInfo | URL, init?: RequestInit) => {
            const body = init?.body
              ? JSON.parse(init.body as string)
              : undefined;
              
            if (body?.thinking?.budget_tokens === -1) {
              body.thinking = { type: "adaptive" };
              return fetch(url, { ...init, body: JSON.stringify(body) });
            }
            return fetch(url, init);
          },
        };
      },
    },

    // Shim: rewrite adaptive -> enabled with sentinel budget so SDK Zod passes,
    // then the custom fetch above detects budget_tokens:-1 and patches to adaptive.
    "chat.params": async (_input, output) => {
      if (output.options?.thinking?.type === "adaptive") {
        output.options.thinking = { type: "enabled", budgetTokens: -1 };
      }
    },
  });
