请问大佬们，Codex是如何接入第三方模型的呢？

ccswitch，下载之后在CC switch 里面配置你要接的 APIkey，切换过去就行了，网上很多教程

https://github.com/coulsontl/ai-toolbox 这个用下来比ccswitch好用

能改配置文件实现，但论方便还是ccswitch，

www.ccswitch.io/zh/download

config里面引用外部端点配置文件即可，第三方工具还是不安全。比如：model_provider = "OpenAI"

model = "deepseek-v4.1-flash"

model_catalog_json = 'C:\Users\Administrator.codex\cpa-models.json'

review_model = "gpt-5.6-luna"

model_reasoning_effort = "xhigh"

disable_response_storage = true

windows_wsl_setup_acknowledged = true

name = "custom"

wire_api = "responses"

base_url = "http://0.0.0.0/v1"

requires_openai_auth = true

http_headers = { "x-openai-actor-authorization" = "local-image-extension" }

cpa-models.json：
