      The previous two articles in this series explained how much you\u2019ll pay per message and how to structure your conversation<\/strong> to minimize the number of messages needed. This one addresses the question that naturally follows: if every reply has a cost, who or what should write it? If you haven\u2019t read them yet, start with the WhatsApp Business API price changes<\/a> and how to lower that bill<\/a>. <\/p>\n\n

      How much does AI cost on the WhatsApp Business API, depending on who you ask?<\/h2>\n\n

      Starting October 1, 2026, every response within the 24-hour window incurs a cost. However , the cost varies depending on who writes the response<\/strong>. Whether the response comes from a person, a bot, or a third-party AI, Meta charges the same service fee per message. If Meta\u2019s AI agent responds, Meta charges for the tokens consumed by that message, and the service fee is not added. <\/p>\n\n

      On top of that, there are costs that don\u2019t appear on Meta\u2019s invoice: your team\u2019s hours, the AI model\u2019s resource usage (if it\u2019s from a third party), and the cost of setting up each option. That\u2019s why the question is no longer just how many messages you send, but how much each response method actually costs you<\/strong>. <\/p>\n\n

      What is a token, and what does AI read before responding?<\/h2>\n\n

      AI models don’t read words; they read tokens: small fragments of text consisting of just a few characters<\/strong>. In Spanish, a word usually takes up one or two tokens, so 1,000 tokens are roughly equivalent to between 600 and 750 words, depending on the model. <\/p>\n\n

      What matters is what the AI reads each time it responds. It doesn’t just read the customer’s last message<\/strong>: in each turn, it re-reads everything it needs to respond.<\/p>\n\n
