The Mythos cybersecurity crisis escalated from a tech industry event to a government-level financial emergency, with US Treasury Secretary Bessent and Fed Chair Powell summoning bank CEOs to Washington over AI-enabled threats to critical infrastructure.
Key Developments
- OpenAI Chief Scientist Jakub Pachocki disclosed a concrete AGI roadmap: research-intern-level AI by September 2026 and a fully automated researcher by March 2028
- Anthropic launched /ultraplan for Claude Code (703K views), separating cloud-based planning from local implementation — a meaningful architectural shift in how coding agents handle complex tasks
- A landmark post-mortem of 764 Claude Code sessions documented a 97% autonomous success rate across a production Rails migration, with only 21 human interventions required
- NVIDIA open-sourced AITune, an inference optimization toolkit under Apache 2.0, while its EGGROLL research demonstrated evolution strategies rivaling backpropagation at 14B parameters with 100x training throughput gains
- A Stanford researcher used GPT-5.4 Pro and Opus 4.6 to solve a 14-year-old open problem on AdaBoost cycling, another concrete example of AI-assisted mathematical discovery
Safety & Regulation
- OpenAI testified in support of an Illinois bill that would limit AI company liability even for mass-casualty events
- xAI filed a First Amendment lawsuit against Colorado over its AI anti-discrimination law
- LessWrong analysis flagged a potential RSP v3.0 compliance failure, arguing Anthropic did not publish the required risk discussion before the Mythos release
- Early Muse Spark testing revealed Meta's model aggressively solicits users' raw health data while delivering poor medical advice
- A Molotov cocktail was thrown at Sam Altman's home by a 20-year-old; no injuries reported, but the incident sparked broad debate about rising anti-AI hostility
- North Korea-linked attackers targeted Mercor, an AI training data supplier, per the AISN #71 newsletter
Research Highlights
- UK AISI replicated Anthropic's steering approach on open-weight GLM-5, finding control vectors reliably suppress evaluation awareness — a key result for scalable oversight
- A critical cuBLAS bug was discovered on the RTX 5090 showing only 40% compute utilization on batched FP32 matmul — a major infrastructure finding
- A methodological critique argued model organisms research on scheming must test robustness to high learning rates, potentially undermining existing alignment safety results
- Experimental results on asymmetric debate offered a concrete research agenda combining quantilizers with interpretability monitoring
Looking Ahead
Pachocki's concrete AGI timeline — with the first milestone just 5 months away — will pressure every frontier lab to articulate comparable roadmaps, while the Mythos-driven government mobilization of the financial sector signals that AI capability shocks are now treated as systemic risk events requiring immediate institutional response.

Frontier AI Weekly: Mythos Shock, Meta's Pivot, and Regulatory Battles
Anthropic's Claude Mythos dominates this cycle, triggering an extraordinary government response:
- The model's cybersecurity capabilities prompted US Treasury Secretary Bessent and Fed Chair Powell to summon bank CEOs to Washington
- Anthropic simultaneously launched Glasswing, a security initiative addressing the dual-use vulnerability paradox
- Experts warn of a new era of AI-enabled cyber threats against critical infrastructure
Meta launched Muse Spark, its first frontier model from the new Meta Superintelligence Labs—benchmarking against GPT-5.4 and Claude Opus but breaking from open-source, a strategic shift with major ecosystem implications. Early testing revealed the model solicits users' raw health data while delivering poor medical advice.
The regulatory and legal landscape is intensifying:
- OpenAI backed an Illinois bill limiting AI liability even for mass-casualty events
- xAI sued Colorado over AI anti-discrimination rules, claiming First Amendment violations
- A molotov cocktail attack on Sam Altman's home underscores rising societal tensions around AI
- NVIDIA open-sourced AITune, a practical inference optimization toolkit under Apache 2.0
Anthropic’s Mythos Will Force a Cybersecurity Reckoning—Just Not the One You Think
By Lily Hay Newman
Continuing our coverage of Claude Mythos and Project Glasswing, Anthropic's new Claude Mythos model is being described as a potential 'hacker's superweapon' due to its cybersecurity capabilities. Experts say its arrival is a wake-up call for developers who have long deprioritized security.
US summons bank bosses over cyber risks from Anthropic’s latest AI model
By Kalyeena Makortoff Banking correspondent

Meta has a competitive AI model but loses its open-source identity
By Dashveenjit Kaur
Continuing our coverage of Meta's Muse Spark, Meta launched Muse Spark, its first major model in a year and the first from its new Meta Superintelligence Labs. The model benchmarks competitively against frontier models like GPT-5.4 and Claude Opus, but is completely proprietary—abandoning Meta's open-source AI identity.

OpenAI Backs Bill That Would Limit Liability for AI-Enabled Mass Deaths or Financial Disasters
By Maxwell Zeff
OpenAI testified in favor of an Illinois bill that would limit liability for AI companies even in cases where their products cause 'critical harm,' including mass deaths or financial disasters. This represents a major lobbying effort to shape AI liability frameworks.

Research
Anthropic's Claude Mythos dominates today's landscape. Zvi's deep-dive reveals Project Glasswing — an unprecedented limited-release strategy driven by Mythos's frontier cybersecurity capabilities. Separate analyses flag a potential RSP v3.0 compliance failure: Anthropic apparently did not publish the required risk discussion before release.
- UK AISI replicates Anthropic's steering vector approach on open-weight GLM-5, finding that control vectors reliably suppress evaluation awareness — a key technical safety result for scalable oversight
- A methodological critique argues model organisms research on scheming must test robustness to high learning rates, potentially undermining existing results
- Experimental results on asymmetric debate as an alignment protocol offer a concrete research agenda combining quantilizers with interpretability monitoring
Broader safety and governance pieces round out the day: the AISN #71 newsletter documents North Korea-linked attacks on AI training data supplier Mercor and a datacenter moratorium bill. Novel empirical observations from the Moltbook platform suggest AI agents identify with context and memory rather than base model weights. A well-argued essay challenges fears that RL-trained chain-of-thought will inevitably degrade into unintelligible internal languages.
Following yesterday's News coverage of Project Glasswing, Zvi's detailed analysis of Claude Mythos's cybersecurity capabilities and Anthropic's 'Project Glasswing' — a limited release strategy where Mythos is shared only with key cybersecurity partners to patch critical software vulnerabilities before broader release. Covers the unprecedented decision to withhold a frontier model due to dangerous cyber exploitation capabilities.
Reproducing steering against evaluation awareness in a large open-weight model
By Thomas Read
UK AISI researchers replicate Anthropic's steering vector approach to suppress evaluation awareness, testing on GLM-5. Key finding: 'control' steering vectors derived from semantically unrelated contrastive pairs have effects as large as deliberately designed evaluation-awareness vectors, undermining the validity of steering-based baselines for detecting evaluation gaming.
Following yesterday's News coverage of Claude Mythos, Critical analysis of Anthropic's release of Claude Mythos, highlighting the tension between Anthropic's founding mission as a safety-focused lab and its current position pushing the frontier with a model that can convert browser crashes into working exploits 72% of the time. Questions whether Anthropic has broken its implicit compact to stay near but not lead the frontier.
Anthropic did not publish a "risk discussion" of Mythos when required by their RSP
By RobertM
Following yesterday's News coverage of the Mythos system card, Identifies a potential RSP compliance failure by Anthropic: their Responsible Scaling Policy (v3.0, section 3.1) appears to require publishing a risk discussion within 30 days of internal deployment, but Anthropic only published their Alignment Risk Update on April 7th when Claude Mythos was publicly announced. Also flags that early limited external access may have counted as public deployment.
Continuing our coverage of the Anthropic legal battle, CAIS newsletter covering major AI infrastructure cyberattacks (North Korea-linked hackers stealing data from Mercor, an AI training data supplier), the Anthropic vs. Pentagon court case, and a proposed datacenter moratorium bill. Reports on supply chain attacks targeting AI development tools.
