Galactica: Meta launches (and pulls in three days) a science LLM
In one sentence Meta unveils Galactica, a 120B-parameter model trained on 48 million scientific papers. The public demo is pulled after three days under a wave of criticism for authoritative hallucinations.
Meta presents an AI specialized in science: trained on millions of papers, it's meant to help researchers write, synthesize, navigate the literature. It's called Galactica. There's a public demo.
Within hours researchers discover the model confidently generates papers that don't exist, made-up biographies, fake but plausible citations. On a sensitive terrain like science, "looks true but isn't" is a disaster.
Three days later Meta pulls the demo. It's the first public case of a large scientific model withdrawn. It becomes a case study on the danger of giving a confident AI to topics where truth matters more than style.
