Future of Life Institute (FLI) — campaign: Asilomar AI Principles (January 2017): 23 principles for beneficial AI development adopted at the Asilomar Conference. 5,700+ signatories including Stuart Russell, Elon Musk, and Demis Hassabis.

NoteThe claim is substantially confirmed on most points: the campaign/principles exist, FLI's coordination is confirmed, the 23 principles are all present and numbered 1-23, and the signature count (5,720) matches the source's stated figure of 5720 as of August 2017. The claim specifies 'as of 2017-01' (January 2017) but the source shows a publication date of 11 August 2017 with 5,720 signatures. This is a temporal mismatch — the claim references January 2017 but the source's data is from August 2017, making the signature count comparison problematic (the principles may not have existed in January 2017 or had fewer signatures then). The source excerpt does not explicitly confirm the three named signatories (Stuart Russell, Elon Musk, Demis Hassabis), though it references a full list available elsewhere. The verdict is 'partial' because the core facts are confirmed but the temporal reference ('as of 2017-01') conflicts with the source's August 2017 publication date, and the specific signatories are not verified in the provided excerpt.
