Meta AI (FAIR) — Market Share: 63%

NoteThe source directly states '63% of training models are built on PyTorch' as of August 15, 2025 (the publication date). The claim states '63% of training models globally use PyTorch (as of 2025)' with exact stored value 63. The source confirms this exact figure for the same time period. The claim's framing of 'Meta AI (FAIR)'s Market Share' is a reasonable interpretation of PyTorch's adoption metrics, as PyTorch is Meta FAIR's creation and the 63% figure represents its market dominance in training models. The temporal alignment (both 2025) and exact numeric match (63) confirm the claim.
