修改 ~/.codex/config.toml：
model_provider = "OpenAI"
model = "gpt-5.4"
wire_api = "responses"
[model_providers.OpenAI]
name = "OpenAI"
base_url = "https://ai.puro.im"
wire_api = "responses"
requires_openai_auth = true然后 ~/.codex/auth.json：
{
"OPENAI_API_KEY": "sk-xxxxxxxxxxxxxxxx"
}验证：
$ codex exec --sandbox read-only "say hi"修改 ~/.claude/settings.json：
{
"base_url": "https://ai.puro.im",
"api_key": "sk-xxxxxxxxxxxxxxxx"
}Claude Code 通过 /v1/messages endpoint 调用 Anthropic 兼容 API。
