In terms of medieval warfare, what Facebook is doing here looks like filling the moat with rocks and dirt. OpenAI is worth billions, Microsoft is spending billions to retrofit most of their big offerings with AI, Google is doubtless also spending billions to integrate AI in their products. Their moat in all cases is “a blob of X billion weights trained on Y trillion tokens”. Facebook here is spending mere _millions_ to make and release competitive models, effectively filling in the moat by giving it to everyone.
