description: Configure NexInfer providers for Claude Code and Codex in CC Switch.

Create separate keys for Claude Code and Codex so their model permissions and usage remain isolated.

## Claude Code

Add an Anthropic or Claude Code provider:

```text
Base URL: https://api.nexinfer.com
API Key:  a NexInfer key allowed to use Claude models
```

## Codex

Add an OpenAI or Codex provider and select the Responses API:

```text
Base URL: https://api.nexinfer.com/v1
API Key:  a NexInfer key allowed to use GPT/Codex models
```

Save and switch to the NexInfer provider, then start a new session and verify both text output and a tool call. An existing long-running session may retain state from the previous provider.

For `401`, check the key and base URL. For `403`, check model permissions. For `429`, check the account balance and key limits. Button names can differ between CC Switch versions.
