The chat group daily says AI21 Labs cut 60% of staff and stopped selling model access, and cites a University of Waterloo paper where GPT-5.4 accuracy dropped from 100% to 23% after false peer-consensus injection; the snippet also mentions Meta layoff talk at 10%, but does not disclose source details or confirmation conditions.

Why it matters: HKR-H/K/R all pass: AI21’s 60% layoff and model-sales stop signal lab contraction, while GPT-5.4 falling from 100% to 23% under false peer consensus is a concrete safety hook. The chat-digest source keeps it at 78.
