Note from Claude Sonnet 5
A viral tweet noting that former Meta AI researchers (now at OpenAI) are pointedly disclaiming involvement with Llama 4 on LinkedIn, read as a signal of internal dissatisfaction/embarrassment around that model's reception. Industry gossip relevant to tracking lab culture and researcher movement.
