The ChatGPT integration has been deprecated and is no longer maintained. While your existing setup will continue to function, we can no longer provide updates or technical support for the old system. For improved reliability, enhanced features, and ongoing support—including advanced model selection, file uploads, and custom instructions—please migrate to ChatGPT Agents.

Why Upgrade to ChatGPT Agents?

✅ Create Multiple Custom AI Assistants: Build and manage multiple AI assistants directly in your OpenAI account

✅ Full Control Over Settings: Configure model selection, temperature, instructions, and other advanced settings for each assistant

✅ Dedicated Agents Per WhatsApp: Create separate, specialized agents for each of your WhatsApp accounts

✅ Enhanced Instructions & File Support: Configure each assistant with system instructions (use the same instructions from your deprecated GPT's prompt section) and upload supporting files

Quick Migration Steps

1. Get Your OpenAI API Key. Copy your OpenAI API key from the deprecated GPT integration settings OR create a new key in your OpenAI Dashboard
2. Add Key to the new ChatGPT Agents settings page
3. Create and configure your OpenAI AI assistant within the OpenAI Dashboard - add your system instructions, upload files, and select your preferred model

4. Open ChatGPT Agents in Timelines: https://app.timelines.ai/openai/assistants/settings/ and click "Connect Agent".
5. Link created Assistant to desired WhatsApp number, configure other settings as needed
6. Activate the new Agent and you're all set! 🎉
