Third-party clients

TRAE Setup

TRAE supports custom models using OpenAI Chat Completions or Anthropic Messages. To avoid Base URL path ambiguity, the recommended setup enables Full URL and uses the complete endpoint.

Use Codex models

Quick settings

Backup URLs are https://jp.icodeeasy.cc/v1/chat/completions and https://sg.icodeeasy.cc/v1/chat/completions.

Steps

1. Open Settings → Models.
2. Click Add Model, then choose Custom Config.
3. Choose OpenAI Chat Completions as the API Format.
4. Enable Full URL and enter https://api.icodeeasy.cc/v1/chat/completions.
5. Enter gpt-5.6-sol as the Model ID and paste your API key.
6. Keep Model Series on Default when unsure; optionally set a display name and context window.
7. Click Add Model. TRAE validates the connection before adding it to the model list.

Use Claude models

Quick settings

Backup URLs are https://jp.icodeeasy.cc/v1/messages and https://sg.icodeeasy.cc/v1/messages.

Steps

1. Open Settings → Models.
2. Click Add Model, then choose Custom Config.
3. Choose Anthropic Messages as the API Format.
4. Enable Full URL and enter https://api.icodeeasy.cc/v1/messages.
5. Enter claude-sonnet-4-6 as the Model ID and paste your API key.
6. Keep Model Series on Default when unsure.
7. Click Add Model and select the new Claude model after the connection check succeeds.

If you receive non_claude_code_client, select a Claude endpoint in the dashboard that allows third-party clients.

Compatibility notes

• TRAE currently documents OpenAI Chat Completions and Anthropic Messages custom formats, not OpenAI Responses API.
• A specific Model Series applies TRAE prompt and parameter adaptations. Use Default unless you know the matching series.
• A successful connection check proves the base request works; Agent tool calls still depend on model and upstream tool compatibility.
