[BUG]供应商为OpenAl Compatible类型的无法使用Claude模型

已经配置了可访问模型：claude-opus-4-6和claude-sonnet-4-6

cch报错返回：No available providers (cch_session_id: sess_mm2taqia_70ae6deb8878)

其它的gpt，gemini以及其它国产模型等都是正常的，只有claude模型有问题

Thank you for reporting this issue.

Analysis:

This is by design behavior, not a bug. The provider selection logic explicitly prevents openai-compatible provider types from handling Claude model requests.

Affected code:

• src/app/v1/_lib/proxy/provider-selector.ts (lines 119-132)

The providerSupportsModel function contains the following logic:

// Case 1: Claude model request
if (isClaudeModel) {
  // 1a. Anthropic provider
  if (isClaudeProvider) {
    // Check allowedModels whitelist
    ...
  }

  // 1b. Non-Anthropic providers do not support Claude model scheduling
  return false;  // <-- This returns false for openai-compatible providers
}

Reason for this design:

1. Claude models (claude-*) require the native Anthropic Messages API format
2. openai-compatible providers use the OpenAI Chat Completions API format
3. The two formats are incompatible - mixing them would cause API errors

Solution:
To use Claude models (claude-opus-4-6, claude-sonnet-4-6), you need to create a provider with providerType set to claude or claude-auth, not openai-compatible.

Provider type usage guide:

• claude / claude-auth: For Claude models via Anthropic API
• openai-compatible: For models via OpenAI-compatible APIs (GPT, Gemini via OpenAI-compatible endpoints, etc.)
• codex: For Codex CLI
• gemini / gemini-cli: For Gemini models

If your upstream provider offers Claude models via an OpenAI-compatible API endpoint, you would need to use model redirection to map Claude model names to the actual model names supported by that endpoint (e.g., redirect claude-sonnet-4-6 to whatever model name the upstream uses).
