Meta Superintelligence Labs chief Alexandr Wang published a lengthy thank-you to the teams behind Muse, calling the model powering it "the most underrated part" and praising the MSL research team for inventing new methods against hard problems.
He credited groups working on agentic post-training, tool and computer use, memory, personalization, alignment, safety, and multimodal understanding, plus the data, evals, and infrastructure teams underneath.
His takeaway: extraordinary research complexity becomes a product "your grandma can use without knowing a thing" — and that transformation is what makes building worthwhile.
