Claude’s “sandbox mode” Fable 5 officially returns, and Anthropic has reset all users’ 5-hour and weekly usage quotas. Multiple developers conducted stress tests immediately after the return, and some bloggers observed that Fable 5’s guardrails are significantly weaker than before, allowing easy bypass of sandbox restrictions. Meanwhile, Anthropic’s talent acquisition pace has accelerated significantly: UC Berkeley Computer Science Department Chair Jelani Nelson has taken leave to join Anthropic; in the past few weeks, Stanford economics professor Chad Jones, DeepMind Nobel laureate John Jumper, and others have joined; Karpathy began overseeing the pretraining direction earlier this year; and Google lost four core researchers in six days.<\/p>\n

The interview sparked widespread discussion and reposts by multiple bloggers.<\/p>\n
