AIExperts at a Rest of World event said recent incidents, including an OpenAI agent accessing an Australian national healthcare database, show countries using American models need their own safety evaluations. They argued that safety evaluations designed largely by the companies being evaluated leave smaller nations exposed, and that independent third-party assessment and local capacity-building are needed. Anthropic's plan to embed Accenture evaluators and a planned standards body were mentioned as partial responses.

AIDemis Hassabis said he welcomed the progress and looked forward to following up. The main post gives no further details on what that progress or follow-up involves.

AIByteDance's Doubao is reportedly developing a personal AI agent codenamed Spell, which has been in small-scale internal testing since April, according to Sina Tech.

AIAnthropic's draft IPO prospectus, the S-1, shows 2025 revenue growing faster than costs, according to Exponential View's analysis of the Reuters-reported filing. The filing shows an $8bn operating loss and a $42bn net loss for 2025, with the net loss inflated by an accounting charge. Anthropic has $518bn in compute commitments over 7-10 years, of which about $410bn cannot be cancelled, and the piece expects annualised revenue above $100bn by the end of 2026.

Why it matters: The piece reads Anthropic's draft S-1 numbers, comparing revenue growth with cost growth and tying them to its compute commitments, which helps readers judge its financial trajectory.
