Let's have two pricing levels. One will be 12.5x more expensive than the other. For the cheaper one, we will get their express permission to train models on their inputs. For the more expensive one, we will still treat their data EXACTLY the same, but we'll lie to them and say that we won't. I've checked in with legal and they raised their sherry glasses and toasted "Gentlemen, TO CRIME".
Easy to comprehend: Trust lost is hard to gain.
Though, it is extremely competitive of Meta to sell Muse Spark (Grok 4.5 / Qwen 3.8 Max level model) cheaper than DeepSeek v4 Flash / MiMo v2.5 / GPT 5.6 Luna, regardless.
There's contractual cover, there are lawyers all over the USA ready to make themselves very rich by creating a class action over it... you don't have to worry! Or, you do, but frankly, only MI6/CIA/Mossad can save you now.
We can make this fun, within 18 months from now, there will be some story / whistleblower like "a inadvertent defect was found that allowed your 'private' data to be used in our training endeavours, we sincerely apologize and have already addressed the issue" - if this does not happened in this timeframe I will donate $1k to a charity of your choice.
People whistleblow on Meta all the time. Most recently they got fined half a billion for suppressing child safety research. Kids getting groomed. It doesn't make a difference to a company that has a net profit of $60 billion a year.
