In a new essay, AI researcher Nathan Lambert argues that open-source AI is entering its most serious viability test to date. The piece frames the next six months as a critical period, with the title itself raising the possibility that open models may have little time left.
Lambert's analysis centers on the current moment rather than a settled outcome. It presents the coming months as an open question, one that will determine whether open-source approaches can remain viable against the pressures facing the field.
Because this brief draws on a single source, there are no conflicting accounts to compare. The argument stands as Lambert's own assessment of the stakes.
