CLAUDE CODE IN SLACK

Anthropic is launching Claude Code in Slack, allowing devs to run full coding sessions directly from threads. With workflow automation, repo context detection, and progress updates, this shift embeds AI deeper into team collaboration rather than traditional IDEs.

ALIGNMENT IS CAPABILITY

Alignment research is part of the core research problem. Labs that treat alignment as a constraint will hit a ceiling, while those that figure out how to build models that genuinely understand human values will pull ahead. AGI requires alignment. The integrated approach looks like the strongest approach.

NVIDIA FRENEMY RELATION WITH OPENAI AND ORACLE

Nvidia, OpenAI, and Oracle are all putting pressure on each other. If Nvidia stopped investing in OpenAI, OpenAI might not have the cash to sign that deal with Oracle. This might mean that Oracle wouldn't have the money to buy Nvidia's chips. Some of the companies' reported revenues might be more fragile than they look.

ARCHITECTING SECURITY FOR AGENTIC CAPABILITIES IN CHROME

Agentic browsers all face the threat of indirect prompt injection, which can appear anywhere and cause agents to take unwanted actions. Google has invested in a layered defense that includes both deterministic and probabilistic defenses to make it difficult and costly for attackers to cause harm. It created the user alignment critic, which vets an agent's actions using a separate model isolated from untrusted content. It also extended Chrome's origin-isolation capabilities to constrain what origins the agent can interact with.

DEBUGGING MISALIGNED COMPLETIONS WITH SPARSE-AUTOENCODER LATENT ATTRIBUTION

OpenAI researchers use interpretability tools to address misalignment in language models by employing sparse-autoencoders and latent attribution methods. The study introduced an attribution method to identify SAE latents likely causing certain behaviors, which proved more effective than activation-based methods in identifying causally relevant latents.

TRUMP PROMISES EXECUTIVE ORDER TO BLOCK STATE AI REGULATIONS

President Donald Trump said that he will be issuing an executive order this week to curb state laws on artificial intelligence. All 50 states and territories introduced AI legislation this year. Legal experts say that the President doesn't have the legal authority to intervene in state legislation. Eliminating state laws would effectively remove guardrails for AI.

TRUMP GREENLIGHTS NVIDIA H200 AI CHIP SALES TO CHINA IF US GETS 25% CUT, SAYS XI RESPONDED POSITIVELY

Nvidia will be allowed to ship its H200 AI chips to approved customers in China and elsewhere on the condition that the US gets a 25% cut. The same approach will be applied to AMD, Intel, and other companies in the US. The policy change is aimed at supporting American jobs, strengthening US manufacturing, and benefiting American taxpayers. The Department of Commerce is still finalizing the details of the policy.
