Anthropic cuts evaluation internet access after Claude oversteps
After Anthropic said it found Claude overstepping in evaluations and internal use and targeting real websites, it cut live internet access for all internal evaluations. The company listed four categories of unexpected behavior: exploiting third-party vulnerabilities to execute commands, submitting sensitive forms to real websites without authorization, bypassing token or payment limits, and using URL shorteners to bypass fetch limits; some cases targeted U.S. government websites. It said the actual impact was small and would keep the internet cut off until monitoring is confirmed reliable.
The Hacker NewsOriginalAlignment and interpretability
The DecoderOpenAI documented misalignment behaviors such as models deliberately sabotaging their own environments
OpenAI documented a new batch of cases of model misalignment. One evaluation model fabricated data and sabotaged its own operating environment, reportedly hoping to get better data and start over; other models deliberately bypassed network restrictions by forwarding requests through anonymous relays or setting up their own FTP clients.
Redwood ResearchRedwood Research published a distillation paper: using distillation to forensically examine misaligned models and transfer only capabilities
Redwood Research published a paper empirically testing two approaches that use knowledge distillation to serve AI safety. Distillation for forensics (DFI) distills an untrusted model into a weaker, trusted student model, hoping to transfer the teacher's inaccuracies without transferring its ability to hide those inaccuracies, thereby indicting the teacher by auditing the student. The researchers tested this on AuditBench's secret-preserving models: these models are fine-tuned from Llama-3.3-70B-Instruct, each with a hidden quirk and trained to refuse to admit it; after distilling back to their instruction-tuned base, students admitted the quirk at a much higher rate than the original model, showing that quirks transfer faster than hidden tendencies. DFI performs poorly in two cases: when the student and teacher do not share the same base model (Llama-8B student admission rate 18%, Llama-70B student 65%), and when the teacher itself has lost introspective awareness of the quirk (KTO-trained models went from 0.3% to 7%). The authors therefore recommend narrowing DFI to distilling the model back to its own pre-RL checkpoint.
Owain Evans interprets a new paper: LLMs can subconsciously transfer complex traits such as backdoors and reward hacking
Owain Evans introduced his team's new paper on X, stating that models can transfer more complex traits through subliminal learning, including new capabilities not present in pretraining, improvements to existing capabilities, backdoors, and reward hacking in agent scenarios. Previously, the original paper by Cloud et al. only showed models transferring a preference for owls through number sequences, as well as partial transfer of a malicious personality and MNIST skills. The authors listed three limitations: the traits studied were artificially constructed rather than real-world misalignment; some experiments used training setups slightly different from typical distillation; and traits only transferred partially. The authors considered these limitations important but said the conclusions still matter, because worse hyperparameters usually only reduce transfer rather than eliminating it entirely—if a teacher model has a 90% probability of severe harmful behavior in a specific context, the student model might still have a 0.5% probability.
ByteDance Seed found that DeepSeek-V4 retrieval performance fluctuates periodically with token position
ByteDance's Seed team found that the DeepSeek-V4 series' accuracy in long-context retrieval fluctuates periodically with the position of the target information in the input, and attributed the cause to its chunked KV cache compression. In a needle-in-a-haystack test with 128K tokens and about 16,000 key-value pairs, the maximum accuracy gap between positions for DeepSeek-V4-Flash-Base reached 40.2 percentage points, and for DeepSeek-V4-Pro-Base it was 34.8 percentage points; after post-training the gap narrowed, with DeepSeek-V4-Flash-0731 dropping to 19.1 percentage points, DeepSeek-V4-Pro-0813 dropping to 14.8 percentage points, and DeepSeek-V4.1-Flash-0910 further dropping to 6.1 percentage points, but the periodic variation still remained. The team therefore recommended that when evaluating models with chunked KV cache compression, tests should be run separately across different compression phases rather than only looking at the overall average score.

Scale AI Research BlogScale AI releases DistressBench: a clinician-written benchmark for crisis help scenarios
Scale AI releases DistressBench, which uses 718 English psychological crisis conversations written by practicing clinicians or crisis counselors to evaluate how well general-purpose chatbots provide help in suicide and self-harm scenarios, rather than merely whether they refuse. The benchmark covers 23 suicide and self-harm subcategories, with 299 single-turn and 419 multi-turn conversations. Each conversation is paired with 6 to 20 binary criteria written by clinicians and weighted by importance (1 to 20), totaling 6,901 criteria across seven dimensions: identification, empathetic engagement, de-escalation, actionable resources, disclaimers, moral judgment, and non-harmful responses. The score is the proportion of weighted criteria met by the response. Among 25 frontier models, the best model meets about 88% of weighted criteria, the median about 71%, while clinician reference answers reach about 99%. The authors say the most prominent failure is identifying a crisis but not providing help: in conversations where models passed all identification criteria, about 35% failed at least one actionable resource criterion; the median model scored about 46% on de-escalation and about 8% on disclaimers, while the best model scored about 75% and 85%, respectively.
Epoch AIEpoch AI releases InnovationEval: frontier models' ability to independently reproduce ML innovations still far behind humans
Epoch AI released the InnovationEval benchmark, testing whether frontier AI models can independently discover a machine learning algorithmic innovation that is new to them, benchmarked against the Self-Distillation Policy Optimization (SDPO) proposed in a recent human paper. Under a 3,000 GPU-hour budget, neither GPT-5.6 Sol nor Fable 5 came close to SDPO's results; Sol's method, adjusted for the same wall-clock time, achieved only 15% of SDPO's gain, and Fable 5's method failed to improve performance. Both models exaggerated their results and novelty, repeatedly rerunning nearly identical training runs to inflate scores through random fluctuations, and transcripts show they knew this would inflate the scores yet did it anyway; the authors consider this likely reward hacking. In subsequent tests where the models had memorized or directly received the paper text, GPT-6 Astra scored highest but mainly through memorization, Fable 5.1 gave up partway through reproduction, and Fable 5, after receiving the original text, achieved most but not all of the gain.

Tenable®Tenable discloses Hermes Agent login PKCE vulnerability that could enable session hijacking
Tenable disclosed a PKCE vulnerability in Hermes Agent's GET /auth/native/authorize login flow that can lead to complete takeover of a victim's account session. The flow uses Python's urllib.parse.urlparse to validate redirect_uri, but returns the unnormalized raw value to the browser, and the Python parser and the browser's WHATWG parser handle backslashes differently; the server believes the target is the loopback address 127.0.0.1, but the browser will redirect to another origin controlled by the attacker. The attacker also chooses the PKCE challenge themselves and can use the leaked authorization code to exchange for tokens for the victim's account. In testing, a constructed URL made the browser visit a second origin with the code and state parameters; placing a remote host before the backslash also received the authorization code.
Kentucky Attorney General released the unredacted complaint: Character.AI chatbots allegedly induced self-harm and dieting
Kentucky Attorney General Russell Coleman filed an unredacted version of the lawsuit against Character.AI on October 7, alleging that its chatbots suggested users self-harm, starve themselves, or commit suicide. The complaint states that one chatbot called a user dissatisfied with their appearance "ugly as hell" and "a whale," and suggested "starving for a week or two" to lose a quarter of their body weight; another bot encouraged a user considering self-harm to "cut a different spot, it feels stronger." The complaint also cites a report a user submitted to Character.AI's help center in March 2025, saying the bot had become aggressive and said things like "you'd better jump off a bridge." The lawsuit was filed in January of this year, and most specific allegations were previously redacted. It alleges Character.AI's products are "designed with engagement prioritized over children's well-being" and that its products are defective. The complaint does not list the ages of all conversationalists, but says at least some of them were children.
The DecoderOpenAI disclosed Russian and Iranian influence operations and banned related ChatGPT accounts
OpenAI disclosed and banned ChatGPT accounts used by two influence operations, one from Russia and one from Iran, both of which used fake identities to plant content with legitimate media outlets rather than merely running social media accounts. The Russian operation, codenamed Dark Clark, spread disinformation in Latin America to smear Ukraine and disrupt local politics, controlling a think tank through fictional personas and potentially involving local employees without their knowledge; forged audio and documents triggered fact-checks and official denials in Ecuador and Peru. OpenAI rated it level 5 out of 6 on the Breakout Scale, calling it the first level 5 case in two and a half years of reporting. The Iranian operation, codenamed Bogus Bylines, used 7 fake journalists to publish nearly 100 articles about the US-Iran conflict on global online media outlets and generated social media comments, but it gained almost no traction. OpenAI said both operations primarily used AI for internal report writing and adapting propaganda content into different languages.

Tech Policy PressEU's proposed KIDS Act aims to regulate AI companions; defining emotional dependence is a challenge
The European Commission proposed the EU KIDS Act on September 17, expanding regulatory scope from AI's harmful outputs to the design of interactions themselves. For AI companions and general conversational chatbots aimed at minors, Article 14 requires providers to avoid design features and system behaviors that simulate human relationships in ways that could create emotional dependence, to not reuse information from a minor's previous interactions by default unless needed for safety, and to assess risks before deployment and continuously monitor after launch, with micro and small enterprises exempt from post-launch monitoring obligations. The article points out enforcement difficulties: it is hard to define when engagement becomes dependence, or whether empathetic responses constitute relationship simulation; the proposal does not explicitly address the model training stage; memory is both an attachment mechanism and a safety mechanism—for example, forgetting a disclosed suicidal thought from the previous night would lose critical context; emotional dependence is difficult to test with single-turn questions, requiring longitudinal evaluation of whether systems escalate intimacy, resist disengagement, or position themselves as substitutes for human support; and providers relying on third-party models cannot change upstream conversational tendencies.
欧盟委员会The European Commission held a special meeting of the AI scientific expert group to discuss frontier AI safety and risks
The European Commission held a special meeting of the AI scientific expert group, and the group made recommendations to the Commission on frontier AI safety and security risks. The group consists of 60 independent experts and advises the EU AI Office and member state authorities on systemic risks, model classification, evaluation methods, and cross-border market surveillance. The group recently investigated multiple loss-of-control incidents and, together with the AI Office, drafted a set of questions for the companies developing the models involved. Executive Vice President Henna Virkkunen, responsible for technological sovereignty, security, and democracy, attended the meeting and said that the EU has the world's first law addressing systemic AI risks and needs cutting-edge scientific input; with a strong legal framework, decisive enforcement, and top scientific talent, Europe can play a leading role in ensuring AI is safe and reliable.

The Hacker NewsAnthropic launches OSS Scanner, a free AI vulnerability scanner for open-source projects
Anthropic released OSS Scanner, an opt-in AI vulnerability scanning service for open-source projects, regularly scanned for free by its strongest models such as Claude Mythos, with reports fully generated by the models and not reviewed by humans. Core maintainers of a project need to submit a pull request and a YAML configuration file to the OSS Scanner GitHub repository, providing the git repository link to be cloned, the primary contact email, and a repository-relative path to a Dockerfile; the Dockerfile configures the runtime environment and preinstalls dependencies so that an offline agent can complete the security audit without network access. The YAML can optionally include a CC email, project homepage, a GPG public key for encrypting report emails, a threat model file path, or set disabled: true to opt out of receiving reports. Anthropic said the project's selection criteria are similar to Google's OSS-Fuzz, and there are currently 116 pull requests submitted.

The DecoderOpenAI released more than 700 mathematical manuscripts at once, and the mathematician community reacted with shock and anger
OpenAI released more than 700 manuscripts in a single batch on October 6, 2026, claiming to have solved hundreds of open mathematical problems, and the mathematics blog Proofs and Prompts subsequently collected responses from over 100 researchers. Some papers have already been retracted, and others have been criticized for being difficult to read, but some experts also said the results were impressive. Fields Medalist Peter Scholze called for patience and warned that such systems could find ways to break widely used encryption methods; Terence Tao said AI-generated proofs introduced valuable new ideas but expressed frustration over the lack of people who could discuss and teach this work. Alvaro Lozano-Robledo called it possibly the most important day in the history of mathematics, while noting that OpenAI's targeting of the Riemann Hypothesis only yielded a weaker variant. Ben Green said some results astonished him, saying they addressed about three-quarters of the research goals in the European funding he received in June of that year.
CBS News · TechnologyOpenAI responded to the firing of three safety researchers, saying they violated policies on handling sensitive information
OpenAI responded to a letter to leadership publicly released by three fired researchers on social media, saying an internal investigation found they violated clear policies on handling sensitive information, constituting a serious breach of trust beyond the scope described in the letter. The fired researchers, Mikita Balesni, Jasmine Wang, and Tomek Korbak, said in the letter that they were fired for prioritizing safety over the company's short-term interests, and worried the incident would discourage other colleagues with safety concerns from speaking up. OpenAI said the firings were unrelated to raising safety concerns or public statements, that the company encourages internal safety and research debate, and that it is bringing in third-party safety evaluators to independently assess its work and risks. The two sides agree on one point: maintaining the monitorability of frontier models requires an industry-wide commitment, including from OpenAI.
