US export directive cuts off Fable 5 and Mythos 5, hardening model access as a controlled good

Anthropic confirmed a government order to suspend all access to two of its models, the clearest sign yet that the government now treats frontier model weights as controlled military goods.

Anthropic co-founder floats recursive self-improvement by 2028

Jack Clark, a co-founder of Anthropic, says AI could help invent its successors with little human involvement, which sharpens the question of whether oversight can keep pace.

New benchmark probes agentic AI for attack surfaces that static tests miss

RIFT-Bench dynamically red-teams autonomous agents built on large language models (LLMs), while a companion paper questions whether "agent" even has a coherent definition.

A proposal to give AI agents cryptographic certificates of correctness

An arXiv paper compiles policy and correctness conditions into witness-checking problems, aiming to make an agent's compliance verifiable rather than assumed.

New work examines whether reasoning distillation losses differ in weight space, not just accuracy

A paper asks whether offline RL objectives that transfer reasoning from large teachers to small students produce genuinely different models, beyond their downstream scores.

Coding tools reposition agents as collaborators, not autocomplete

Cursor's Compile 26 announcements, Anthropic's Claude Tag, and Nvidia's agent toolkit all point the same way: agentic AI moving into real engineering workflows.
