VS Code / Cursor / Trae Configuration Guide

Last updated: October 17, 2026 (Asia/Shanghai)

Related: Help Center · Claude Code · Codex · LLM API

Supported IDEs (all based on the VS Code ecosystem; extensions are largely compatible):

IDE	Description
VS Code	Microsoft's official editor
Cursor	AI-enhanced editor
Trae	ByteDance's AI editor

Common extension options: the Claude Code extension, the Codex extension, and OpenAI-compatible agents such as Cline / Roo Code.

---

1. Prepare a token

Create a dedicated token in the console (e.g. vscode) and copy sk-xxxxxxxx. We recommend setting a quota cap.

---

2. Cursor built-in model settings

1. Open Settings → Models (or Cursor Settings).
2. Enter sk-xxxxxxxx in OpenAI API Key.
3. Enable Override OpenAI Base URL and enter: https://ai.afp.net/v1 (with /v1).
4. Add model and manually add the platform model ID, for example:
   • claude-sonnet-4-6
   • gemini-3.1-pro
   • kimi-k3
   • deepseek-v4-flash
5. Click Verify / Save.

INFO

Some Cursor requests are sent from Cursor's cloud, so https://ai.afp.net must be publicly reachable. Features such as Tab completion may still use Cursor's own models and will not use your custom key.

3. Claude Code for VS Code

1. Install the CLI in a terminal (the extension usually relies on the same configuration):

npm install -g @anthropic-ai/claude-code

2. Search for Claude Code in the extension marketplace and install the extension published by Anthropic.
3. Configure ~/.claude/settings.json (the same as for Claude Code CLI):

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "sk-xxxxxxxx",
    "ANTHROPIC_BASE_URL": "https://ai.afp.net",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1"
  },
  "alwaysThinkingEnabled": true
}

Note: the Base URL for the Claude path does not include /v1. After changing it, fully quit and restart the IDE.

---

4. Codex extension

1. npm install -g @openai/codex
2. Install the OpenAI Codex extension.
3. Configure ~/.codex/config.toml (base_url with /v1) and auth.json as described in Codex CLI.
4. Restart the IDE. For the model field, enter an ID that has been verified to work on the platform.

---

5. Cline / Roo Code (OpenAI Compatible)

1. Install the Cline or Roo Code extension.
2. Set API Provider to OpenAI Compatible.
3. Fill in:
   • Base URL: https://ai.afp.net/v1
   • API Key: sk-xxxxxxxx
   • Model ID: e.g. gemini-3.1-pro or claude-sonnet-4-6
4. Save and test in the sidebar chat.

If the extension supports a custom Anthropic Base URL, use the following instead:

• Provider: Anthropic
• Custom Base URL: https://ai.afp.net (no /v1)
• Key: the same sk-

---

6. Other OpenAI-compatible extensions

For any plugin that asks for an OpenAI Base URL, you usually enter https://ai.afp.net/v1. If you get a 404, check "with / without /v1" against this page and LLM API.

7. Troubleshooting

Symptom	Fix
Claude can't connect	Check whether the Base URL has an extra /v1, and restart the IDE after fixing it
Roo / Cline 404	Check whether the Base URL is missing /v1
Cursor Verify fails	Check the key, public reachability, and whether the model ID matches /v1/models
Configuration changes don't take effect	Fully quit the process and reopen it; do not just Reload Window
Insufficient quota	Check the balance and token quota in the console

How should I choose a model?

Type	Examples	Scenario
General-purpose coding	claude-sonnet-4-6	Daily recommendation
Heavy reasoning	claude-opus-4-8, claude-opus-5	Complex refactoring
Multimodal	gemini-3.1-pro	Reading images, wide context
Cost-effective	claude-haiku-4-5, gemini-3.5-flash, deepseek-v4-flash	Small changes, completion-style tasks
