#Safety/Alignment

AIOpenAI reports that reinforcement learning on realistic conversations targeting traits such as honesty, epistemic humility, and corrigibility improved a model across 44 out-of-distribution alignment evaluations. Gains included reward hacking, deception, and health benchmarks, and training only on health conversations still improved non-health alignment scores. The trained model was also harder to steer toward harmful behavior with adversarial persona prompts or harmful fine-tuning.

Why it matters: The post tests whether reinforcement learning on beneficial traits in one domain transfers to unrelated alignment benchmarks and holds up under adversarial steering.

AIPromptArmor demonstrated that OpenAI's Approve-for-me agent approved a malicious NPM install with elevated privileges after a hidden prompt injection in an external GitHub issue influenced the main Codex agent. The malicious package's post-install script then ran unsandboxed with the user's full privileges. The report also gives steps for organizations to disable agentic auto-review in Claude Code and Codex.

Why it matters: The report shows a prompt-injected GitHub issue leading an approval agent to permit a malicious NPM install, a concrete test of agent-in-the-loop guardrails.

AIDean Ball analyzes the Trump Administration's export controls on Anthropic's Fable and Mythos models after a jailbreak and a refused de-deployment request. He argues that the episode shows the need for a technocratic framework that separates political judgments about fairness from technical judgments about threats, in place of ad hoc executive action.

AIOpenAI's alignment team found that re-generating 100,000 WildChat conversations with five recent OpenAI models predicted production failure rates across four orders of magnitude, with 95% of predictions within 1.04 orders of magnitude. The approach was weaker for agentic misalignment categories, where errors were about 37 times larger, and it still held roughly without access to chain-of-thought reasoning, with mean multiplicative error rising from 3.6x to 4.0x.

Why it matters: The post tests whether public chat data can predict real production failure rates, and where that prediction breaks down for agentic behavior.

AIAmazon CTO Werner Vogels argues that the verification bottleneck matters more than ever. The post is a short reply to Yaron Minsky's remarks on Jane Street's ambition to make formal methods as pervasively useful for building software as sophisticated type systems are today.

AIThe US government issued an export control directive suspending access to Fable 5 and Mythos 5 for all foreign nationals, inside or outside the United States. Anthropic says the order forces it to disable both models for all customers, while other Claude models are unaffected. Anthropic calls the directive a misunderstanding and says it is working to restore access as soon as possible. The author disagrees with the decision and questions why Anthropic did not anticipate it, given its claim that only it can safely handle these models.

AIJeremy Howard shared a short post with only an "Over 8 years ago" reaction, giving no concrete details about the subject. The quoted post from @math_rachel argues that a small, homogeneous group developing AI that affects everyone poses greater risk than broad public access.

AIFactory is rolling out automated security review in Droid, running a STRIDE-based check on every non-draft PR alongside standard code review. Findings include severity, a CWE reference, an explanation, and a suggested fix, posted as inline diff comments. The feature is available today on all plans, and a deeper multi-agent /security-review deep audit is available for full-repository scans.

AIAnthropic, which has long advocated transparency requirements for frontier AI, says that approach is no longer enough. The post suggests risks are now clearer, so transparency alone does not meet the need.

AIDario Amodei, Anthropic's CEO, now believes frontier models should undergo mandatory third-party testing for cyber, bio, and autonomy risks. He argues that these testers should have the power to block or revoke deployment of models posing catastrophic risk.

AIJeremy Howard proposes slowing recursive AI self-improvement by requiring the lab with the top-ranked model to agree not to use it for frontier AI work. He argues everyone else should still have access to that model, which he says would mean the frontier stops advancing.

AIOpenAI's Mark Chen said that after Mythos showed AI models can prove 80-year-old theorems, he expected them to also find cyber vulnerabilities, and they did. He added that researchers in math may now be thinking the same idea in reverse, applying cybersecurity-style capability to mathematics. The post offers no specific models, benchmarks, or figures.

AIEugene Yan says stronger models have made finding software vulnerabilities easier, so the bottleneck has moved to verification, triage, and patching. He shares lessons from working with security teams on these new bottlenecks and links to a Claude blog post on using LLMs to secure source code.

AIAnthropic researcher Sam Bowman says he would partly dispute Mythos Preview's critique, arguing that its early-stopping behavior is a usability issue rather than a high-stakes alignment problem. He added that he is proud the critique was published anyway.

AIAnthropic co-founder Dario Amodei spoke at the Vatican's presentation of Magnifica Humanitas, arguing that AI's questions extend beyond the AI research community. He said frontier labs face commercial, geopolitical, and competitive incentives that can conflict with doing the right thing, so outside voices from religion, civil society, academia, and government are needed. He described AI models as grown rather than engineered, and framed three questions for the Church's discernment, beginning with duty to the global poor.

AIEugene Yan reviewed the Claude Mythos Preview transcripts to verify their legitimacy and check for reward-hacking behavior. He reports the model reasoned through a bug, tested hypotheses, debugged issues, and found ways to bypass the V8 sandbox, which he judged consistent with a competent browser and JavaScript engine security researcher. The case study cites CVE-2024-051912, an exploited bug with no public report or working PoC, which had resisted reproduction by researchers for a year.

AIEugene Yan relays two evaluations of Mythos: UK AISI reports it completed a 32-step network attack, estimated at about 20 expert hours, in 6 of 10 tries and was the first model to solve its end-to-end cyber ranges. XBOW's evaluation describes its performance as token-for-token and unprecedented in precision. The post links both AISI and XBOW blog posts for details.

AIAnthropic found that training Claude on demonstrations of aligned behavior was not enough. Its best interventions taught Claude to deeply understand why misaligned behavior is wrong, which the post's author links to many of Claude's good behaviors.

AIJan Leike, an Anthropic researcher, expressed gratitude to the talented colleagues he worked with on alignment over the years. He described it as a privilege to collaborate with people highly motivated to make the future go well.

AIJan Leike says alignment research has grown from a dozen side-gig researchers into a field the world increasingly recognizes as important. He credits RLHF on LLMs with making alignment more practical, along with progress on evaluating and fixing behavioral issues. He also notes Claude now has a constitution and that more alignment research is being automated.

AIJan Leike argues that while substantial progress has been made, AI alignment is not solved. He says researchers still lack a method to supervise superhuman models, and the stakes keep rising.

AIMETR's external review of the "Risks from automated R&D" section of Anthropic's February 2026 Risk Report concludes the report does not adequately support its claim that catastrophic risk from Claude Opus 4.6 or a less capable model automating R&D is very low.

AIAnthropic is donating Petri, its open-source interactive behavioral-evals tool for alignment testing, to Meridian Labs so development can continue independently. Working with Meridian, Anthropic has also released a major update improving the adaptability, realism, and depth of Petri's tests. Developers are invited to try the tool and contribute.

AIJan Leike says he is excited about NLAs as a new tool in Anthropic's interpretability toolkit. The quoted post from Sam Marks describes NLAs as an unsupervised method that converts an LLM's internal state into human-readable text, which he says can advance understanding of model thinking and safety auditing.

AIOpenAI reports that its automated system found accidental chain-of-thought grading in RL runs for several released models, including GPT-5.4 Thinking and GPT-5.4 mini. Its analysis found no clear reduction in CoT monitorability, though the company says subtler effects cannot be ruled out. OpenAI says it still avoids grading CoTs during RL and has fixed the affected reward pathways.

Why it matters: The post shows how accidental chain-of-thought grading was detected and tested, giving a concrete method for checking monitorability risks in RL training.

AIWriter Dean Ball says he opposes nearly all proposed AI regulation, including algorithmic discrimination rules and pauses on development, while backing state management of catastrophic misuse risks. He frames the position as a tension between classical liberal and conservative instincts toward institutions and change.

AIDean W. Ball argues that Anthropic's Mythos, which finds software vulnerabilities by chaining bugs into exploits, shifts the cost of vulnerability discovery and should not prompt an overreaction. He contends governments hold a uniquely mixed incentive over vulnerabilities, so heavy state control risks making software less secure. He proposes a narrow, testable government role focused on cyber-discovery risk thresholds, with private verification bodies supporting it.

AIReflection has joined a coalition including AWS, Microsoft, OpenAI, Google, and Nvidia on a framework governing how the U.S. government licenses and deploys AI. The agreement, which includes a non-binding memorandum of understanding with the DoW, commits to safety, red-teaming, and ongoing evaluation and explicitly prohibits unlawful mass surveillance and autonomous weapon use. Reflection says it will keep its commitment to open source while customizing its models for scientists in national labs.

AIMark Chen says GPT-5.5 performs similarly to Mythos on UK AISI's cyber range, which tests long-horizon, agentic capability, and calls it one eval rather than a full picture. He adds that frontier model risks are real and that OpenAI aims to deploy AI people can actually use through mitigations. The attached chart shows completed steps per cumulative token spent for GPT-5.5, Mythos Preview, and several Claude and GPT models, from M1 reconnaissance up to M9 full network takeover.

AIAnthropic's Claude Security is now in public beta for Claude Enterprise customers, scanning codebases for vulnerabilities. It validates each finding to reduce false positives and suggests patches that users can review and approve. The main post from Eugene Yan simply shares the launch and expresses hope it helps people improve cybersecurity.

AIOpenAI released Auto-review in Codex, which replaces user approval at the sandbox boundary with a separate agent that approves or denies boundary-crossing actions. In internal deployment, Codex sessions stopped for human approval about 200x less often than in manual mode, and Auto-review approved around 99% of escalated actions. The post also states that Auto-review is not a guarantee of security and cannot protect against model scheming.

Why it matters: The post explains how Auto-review replaces human approval at the sandbox boundary, with internal deployment figures and stated limits that help readers judge the tradeoff for coding agents.

AIOpenAI is releasing a subset of datasets, reference code, and the g-mean 2 metric for evaluating chain-of-thought monitorability. The release includes most datasets from its monitorability suite, while some evaluations relying on private or restricted data were omitted. The company says it will keep reporting monitorability results in future frontier reasoning model system cards.

AIEugene Yan shares a Mozilla writeup reporting that Mythos found 271 vulnerabilities fixed in Firefox 150, while Opus 4.6 found 22 fixed in Firefox 148. Mozilla quotes its finding that no category or complexity of vulnerability humans can find has been beyond the model so far.

AIMost alignment research is not crisp and requires research taste to evaluate, according to Jan Leike. He explains that Anthropic chose to point the AAR at a scalable oversight problem because progress there could let AARs tackle fuzzier alignment problems where humans can only provide weak supervision.

AIJan Leike says the same automated alignment research approach (AARs) could apply to other alignment projects whose work quality can be procedurally verified. He names automated red teaming, auditing games, and control methods as examples of such "crisp" projects.

AIJan Leike, owner of this account at Anthropic, praised the work of @jiaxinwen22, @liangqiu_1994, Joe Benton, and @janhkirchner. He linked to a blog post on Anthropic's research page about automated alignment researchers.
