ChatGPT on WeChat Setup Guide

更新日: 2026-06-06

Overview

ChatGPT on WeChat is a widely used WeChat bot project that can route private and group chat traffic through Crazyrouter. The safest rollout is to keep its standard OpenAI-compatible configuration and validate one production-verified model before expanding the bot behavior.

Recommended First-Pass Setup

open_ai_api_base: https://api.crazyrouter.com/v1
first validation model: gpt-5.5
keep the initial allowlist small so troubleshooting stays simple

Recommended Models

Scenario	Model	Description
First-pass route validation	`gpt-5.5`	Verified successfully in Crazyrouter production on March 23, 2026, and best for the OpenAI-compatible baseline
Higher-quality long replies	`claude-opus-4-8`	Better for complex explanations, summaries, and longer text
Gemini fallback path	`gemini-3.1-pro`	Useful as a second vendor-compatible validation path

Suggested Validation Order

Create one dedicated token
Start with one model: gpt-5.5
Send Reply only OK in a private chat first
Confirm the request appears in Crazyrouter logs
Only then expand group triggers, prefixes, and additional models

WeChat bot projects must comply with WeChat usage policies. Avoid sending messages too frequently to prevent account restrictions.
