ChatGPT on WhatsApp: What Changed in 2026, and What You Can Still Build

Short answer: you cannot use ChatGPT on WhatsApp in Malaysia any more. OpenAI retired its 1-800-ChatGPT number on 15 January 2026, and Meta changed the WhatsApp Business Solution terms to bar general-purpose AI assistants from the platform. ChatGPT came back on WhatsApp in the European Economic Area in June 2026 after a European Commission intervention. That ruling covers the EEA. Malaysia is not in it.

Most of what you will find searching this question was written while it still worked, which is why it does not match what you are seeing on your phone. Here is the current position, what Meta actually banned, and the part that matters commercially: what is still expressly allowed.

What happened, in order

In December 2024 OpenAI put ChatGPT on WhatsApp through a number called 1-800-ChatGPT. It was genuinely popular. OpenAI has said more than 50 million people used it, which for a phone number is not a small thing.

In October 2025 Meta updated the terms of the WhatsApp Business Solution. The new wording bars providers of AI and machine-learning technology, including large language models and general-purpose AI assistants, from using the Business API where that technology is the primary functionality being provided. The rule applied to new API accounts from 15 October 2025, and existing accounts were given until 15 January 2026 to comply.

That date is why ChatGPT left. OpenAI published a transition notice telling users to move to the app or the web, and 1-800-ChatGPT was retired on 15 January 2026.

Then it split by region. In June 2026 the European Commission required Meta to restore third-party general-purpose AI assistant access to the WhatsApp Business API in the EEA while an antitrust investigation continues. So a user in Ireland can message ChatGPT on WhatsApp today. A user in Malaysia cannot. Same app, different regulator.

The distinction Meta actually drew, which most coverage got wrong

This is the part worth reading carefully, because a lot of Malaysian business owners read the headline as "WhatsApp is banning AI chatbots" and started worrying about a system they had already paid for.

Meta did not ban AI on WhatsApp. It banned the AI itself being the product. The restriction targets general-purpose assistants distributed through the Business API, where someone messages the number to get an open-ended AI to talk to. ChatGPT and Perplexity are the obvious examples.

What remains expressly permitted is the thing the Business API was built for in the first place: a business talking to its own customers. Meta's own framing is that the Business API was designed for companies to communicate with their customers, not as a distribution channel for standalone AI assistants.

In practice, these are all still allowed, and all still allowed to be AI-powered:

• Customer support and FAQ handling for your own products and services
• Appointment booking and rescheduling
• Order status, delivery tracking, and post-purchase updates
• Lead qualification and routing to the right salesperson
• Notifications, reminders, and confirmations

The test is roughly: is the customer messaging you about your business, or messaging you to use an AI? The first is a business assistant. The second is a general-purpose assistant, and that is the one that is no longer allowed.

So what can a Malaysian business actually run on WhatsApp today?

An AI assistant scoped to your own operation, on the official WhatsApp Business API, using whichever model you choose underneath. The model is not the issue. What matters is that the assistant is bounded to your business rather than offered as a general chatbot.

Concretely, that means it can be trained on your product catalogue, your pricing rules, your booking calendar, and your policies. It can read your stock or order system and answer from live data. It can hold a conversation in Malay, English, Mandarin or a mix of all three, which is what Malaysian customers actually type. And it can escalate to a human with the full conversation attached, rather than starting the customer over.

What it should not do is answer "write me a poem" or "what is the capital of Peru". Not because it technically cannot, but because an open-ended assistant is the category Meta closed. Scoping it to your business is both the compliant choice and, in our experience, the one that performs better anyway. A bot that tries to be ChatGPT gives worse answers about your own products than a bot that only knows your products.

If you only wanted ChatGPT for yourself

Then none of this applies to you and you do not need a business solution. Use the ChatGPT app or the website. Nobody should be selling you a WhatsApp Business API deployment to solve a problem the free app solves. We would rather say that here than in a sales call.

What this costs if you do want it for your business

Three separate costs, and vendors tend to blur them:

• The build. One-time. It covers the integration, the conversation design, the guardrails, and connecting whatever system holds your answers.
• Meta's per-message fee. Charged by Meta, varies by message category and recipient country, and it scales with your volume rather than with anyone's work. Check Meta's current WhatsApp pricing rather than a figure in any proposal, including ours.
• The model. Per-token cost of whichever AI you run underneath. Usually the smallest of the three, and often mispresented as the main cost.

Our AI cost calculator breaks the running costs down in ringgit, and the WhatsApp AI chatbot page covers what the build itself involves. If you want the full shape of a real project including the Meta template rules that catch people out, this walkthrough is the honest version.

The one thing to check before you sign anything

Ask your vendor which category their bot falls into under Meta's terms, and get the answer in writing. A vendor who cannot tell you the difference between a general-purpose assistant and a task-specific business assistant is a vendor who has not read the terms their build depends on. That is a cheap question that tells you a lot.

Frequently asked questions

Can I still use ChatGPT on WhatsApp?

Not in Malaysia. OpenAI retired its 1-800-ChatGPT WhatsApp number on 15 January 2026, and Meta changed its WhatsApp Business Solution terms to bar general-purpose AI assistants from the platform. ChatGPT was reinstated on WhatsApp in the European Economic Area in June 2026 after a European Commission intervention, but that ruling applies to the EEA only. Malaysia is not covered.

Did Meta ban all AI chatbots on WhatsApp?

No. Meta barred general-purpose AI assistants where the AI itself is the product being distributed, such as ChatGPT or Perplexity. Task-specific business bots remain expressly permitted, including customer support, appointment booking, order tracking, notifications, and lead qualification. A business running an AI assistant for its own customers is not affected.

Can a Malaysian business still put AI on WhatsApp?

Yes. You can run an AI assistant on the WhatsApp Business API as long as it is scoped to your own business rather than offered as a general-purpose assistant. It can answer questions about your products, check order status, book appointments, qualify leads, and hand over to a human. That is the permitted category, and it is what most businesses actually wanted.
