What happens if my product exceeds the Llama MAU limit? You must request a license from Meta. Request, not buy. The terms get negotiated at that point. That is the Llama 4 community license 700M MAU threshold explained in one paragraph, but the details are where people trip.
Here is what people get wrong most often: the threshold is not per app. Three products on Llama count together toward the 700 million. It covers fine-tunes and distillations too. You cannot reset the counter by fine-tuning, because the clause follows the lineage of the weights. If it traces back to Llama, it counts. The threshold is measured across your products using Llama, per calendar month.
Cross the line without asking and you are outside the license grant. In practice Meta would come talk to you, and suddenly you are negotiating from a weak position. Not a position I would pick for myself.
Now, some perspective. This clause exists for the handful of companies on earth that could plausibly hit 700M MAU. If that is not you, file it under good-to-know and move on. If it might be you someday, talk to Meta's licensing team early. Lawyers love early. Founders who call before the crisis get better outcomes than founders who call during it.
An AI model commercial rights lookup tool can flag this kind of clause in seconds, but only if it knows your user count is heading in that direction. The threshold is not a secret. It is just easy to ignore until it matters. For commercial use AI model clearance on the biggest products, this clause is the one that decides the outcome.
I track MAU-style thresholds and other gotchas across 200 models at localaitools.fyi, and I write commercial-use clearance reports before you ship.
