Three things changed in AI and business messaging this week, and two of them have dates attached. Here is what each means for you.
1. WhatsApp now charges for messages that used to be free
What changed: Since 1 October 2026, Meta charges for utility messages, such as booking confirmations, reminders and order updates, even when they're sent inside the 24-hour window after a customer has messaged you. They were free in that window from July 2025. Plain replies to customers ("service" messages) remain free for the first 1,000 a month per business number, then are charged per message.
Does it affect me? Only if you use the WhatsApp Business Platform (the API), usually through a provider or a chatbot. The free WhatsApp Business app on your phone is not affected.
What to do: Compare your October and September bills from your provider. If reminders or confirmations went up, check whether all of them are needed, and whether some could be sent as ordinary replies. Our AI cost guide has been updated with the current rates.
2. WhatsApp API accounts must switch to rupee billing by 31 December
What changed: Meta's pricing page says eligible businesses must move their WhatsApp messaging accounts to INR billing by 31 December 2026. From 1 January 2027 it will stop delivering messages from accounts still billed in other currencies.
Does it affect me? If you, or a provider on your behalf, run a WhatsApp API account that's still billed in US dollars.
What to do: Ask your provider one question: "Is our WhatsApp account billed in INR, and if not, when will it be migrated?" Get the answer in writing.
3. OpenAI is retiring older models from its API on 14 January
What changed: OpenAI has announced that several older models, including GPT-4o, GPT-4o mini, GPT-4.1 and GPT-4.1 mini, will be removed from its API on 14 January 2027, according to multiple reports of its deprecation notice.
Does it affect me? Not if you use the ChatGPT app. Possibly, if an agency or developer built you a chatbot, WhatsApp assistant or tool on OpenAI's API in 2024 or 2025. If they haven't updated it, it may stop working or change behaviour.
What to do: Ask your vendor: "Which AI model does our assistant use, and is it affected by OpenAI's January 2027 retirements?" A good vendor will already know. This is one of the questions to ask an AI agency at the start, not when something breaks.
Also this week: DPDP consent managers
The part of the DPDP Rules that covers consent managers, registered companies that will help people manage their consents across businesses, comes into force on 13 November (some sources say 14 November). It's a milestone in India's data protection rollout, but most small businesses don't need to do anything because of it. Your main obligations apply from May 2027. Our DPDP guide for small businesses lists what to prepare.
This week's checklist
- If you use a WhatsApp API provider, compare your September and October bills
- Ask your provider whether your WhatsApp account is billed in INR
- Ask whoever built your chatbot which AI model it uses
- Note 31 December and 14 January in your calendar
- No action needed on DPDP consent managers; keep working through the DPDP checklist
AI This Week is a short Monday note on changes that matter to Indian businesses. Prices and dates come from the providers' own pages where we could check them, and from multiple news reports where we couldn't.
