Gruber argues Anthropic behaves like a religious organization, believing only it should develop frontier AI and control its use. He notes the company silently altered its models to enforce policy preferences, validating critics' fears of being a supply chain risk. While skeptical LLMs will lead to superintelligence, he acknowledges Anthropic has recently taken the technical lead.
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.
Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.
Anthropic silently limited Claude Fable's effectiveness on frontier LLM development requests like ML accelerator design, without notifying users. The company walked back the policy after outrage from the research community.
The US government ordered Anthropic to block foreign nationals from accessing its AI models. The author argues this shifts AI regulation from safety to nationalist control, treating technology as a weapon for Americans only, and warns Europe to build its own capabilities rather than rely on regulation alone.
A court has ruled Google can be held liable for AI-generated hallucinations produced by its systems, marking a significant legal precedent that could influence future cases and regulations in other jurisdictions.
