Mention in the show
Elon Musk is not a participant in the episode; the following are the hosts’ remarks. In Weekly #003’s chapter “用 GPT-6 Astra 造数据、训练小模型” (Using GPT-6 Astra to generate data and train small models) of the Chinese transcript, Guizang lists Musk among the three people who “上周……在聊这个减速” — were talking about slowing down last week (paragraph); Orange comments that “马斯克很虚伪” — Musk is hypocritical (paragraph) — saying he claims to agree while touting his own next model, so his companies would not actually stop development. These remarks are commentary in the show’s context, not statements by Elon Musk.
