These improvements have been driven by several interacting factors including scalable transformers architectures, improved captioning […]

AI’s Affordability Crisis

ai’s-affordability-crisis

A year ago in The Back Of The AI Envelope I pointed out that the AI platforms were running the drug-dealer’s algorithm, ”the first one’s free”.
