@AlexaZhou #20 我测试了 DespSeek 的模型，在 claude code 和 codex 有问题。

版本：
2.1.185 (Claude Code)
codex-cli 0.139.0

claude 的错误：
There's an issue with the selected model (deepseek-v4-pro). It may not exist or you may not have access to it. Run /model to pick a different model.

codex 的错误：
⚠ Model metadata for `deepseek-v4-pro` not found. Defaulting to fallback metadata; this can degrade performance and cause issues.

■ unexpected status 404 Not Found: 404 Not Found, url: http://ai-gateway.mac.local/llm/v1/chat/completions/responses

相关配置：
```
cat ~/.codex/config.toml

model_provider = "custom"
model = "deepseek-v4-pro"
model_reasoning_effort = "xhigh"
personality = "pragmatic"


[model_providers.custom]
name = "custom"
base_url = "http://ai-gateway.mac.local/llm/v1/chat/completions"
wire_api = "responses"
requires_openai_auth = true
```

claude code 通过环境变量设置：
```
export ANTHROPIC_BASE_URL=https://ai-gateway.mac.local/llm/v1/messages
export ANTHROPIC_AUTH_TOKEN=xxx
export ANTHROPIC_MODEL=deepseek-v4-pro
export ANTHROPIC_DEFAULT_OPUS_MODEL=deepseek-v4-pro
export ANTHROPIC_DEFAULT_SONNET_MODEL=deepseek-v4-pro
export ANTHROPIC_DEFAULT_HAIKU_MODEL=deepseek-v4-flash
export CLAUDE_CODE_SUBAGENT_MODEL=deepseek-v4-flash
export CLAUDE_CODE_EFFORT_LEVEL=max
