U.S. Government Orders Anthropic to Shut Down Claude Fable 5 and Mythos 5 Over Security Jailbreak
The U.S. government on Friday ordered Anthropic to immediately shut off global access to Claude Fable 5 and Claude Mythos 5, citing national security concerns over an identified jailbreak vulnerability. Anthropic received the directive at 5:21 pm ET and complied while publicly disputing the decision, arguing that a narrow jailbreak should not trigger a commercial recall affecting hundreds of millions of users. The company warned the standard would effectively halt all new AI model deployments. Mythos has been restricted since April due to its ability to find software security vulnerabilities. Fable 5, released three days prior, was a safety-guardrailed public variant blocking high-risk responses in cybersecurity and biology.

Microsoft SkillOpt Open-Source Framework Automatically Upgrades AI Agent Skills Without Retraining Model Weights
Microsoft has released SkillOpt, an open-source MIT-licensed framework that applies deep-learning optimization principles to automatically improve AI agent skills without modifying underlying model weights. Traditional agent skills were hand-crafted or unreliably self-revised; SkillOpt treats the skill document itself as a trainable object, iteratively exploring instruction modifications based on performance feedback. Benchmarks show it significantly boosting accuracy for GPT-5.5 and Qwen across industry evaluation suites. The creators describe the deep-learning analogy as operational rather than decorative, avoiding instability common to other text optimization approaches. Compact, transferable skill artifacts produced by SkillOpt allow agents to adapt to new domains without retraining the underlying model.

Agile Robots Showcases Agile ONE Humanoid and Franka Robotics Platforms at RTJ 2026 in Nagoya
Agile Robots demonstrated its Agile ONE humanoid and Franka Robotics collaborative arm systems at Robot Technology Japan 2026, held June 10–12 in Nagoya. The showcase highlighted Agile’s proprietary force-control technology, which enables robots to detect and respond to subtle contact forces during sensitive manipulation tasks. Agile ONE targets industrial and research applications, while Franka Robotics systems, acquired by Agile in 2023, serve research and collaborative automation markets. The RTJ 2026 showing was one of Agile’s first major Asia-Pacific demonstrations of its combined physical AI portfolio. Force-control capability is increasingly viewed as a key differentiator separating capable humanoid platforms from simpler motion-replay systems.

RLWRLD and Nvidia Launch DexBench to Standardize Humanoid Robot Dexterity Evaluation
RLWRLD has partnered with Nvidia to launch DexBench, a universal benchmark for evaluating humanoid robot dexterity, addressing a gap where fine-grained manipulation tasks such as precision assembly and sorting lack standardized measurement. The benchmark integrates with Nvidia’s open Isaac Lab and Isaac Lab-Arena simulation frameworks and is paired with a new data standard for dexterous manipulation training datasets. DexBench targets tasks requiring multi-finger coordination and high-resolution force feedback — capabilities where competing humanoid platforms currently cannot be objectively compared. The initiative aims to give the robotics industry a common reference point as dexterous manipulation emerges as a key frontier in physical AI development.

Sharpa Wave Tactile Hands Debut in Nvidia and Unitree H2 Plus Humanoid Reference Design
Sharpa has integrated its Wave five-finger tactile robot hands into the Unitree H2 Plus humanoid reference design, built on Nvidia’s Isaac GR00T development framework, making it the first GR00T-based humanoid platform to include tactile manipulation technology. Each Wave hand features 22 degrees of freedom and more than 1,000 tactile sensing points per fingertip. With both hands installed, the H2 Plus reaches 75 degrees of freedom across the full body. The Nvidia-Unitree reference design provides robot developers a validated hardware baseline for manipulation applications, reducing integration time. Sharpa’s high-density tactile sensing enables the platform to handle delicate objects without relying solely on vision-based guidance.

Hackers Breach Microsoft Open Source GitHub Projects to Steal AI Developer Passwords
Hackers injected password-stealing malware into at least 70 Microsoft open source projects on GitHub, forcing the company to disable compromised repositories during its investigation. Affected projects included Azure cloud tools and developer utilities used alongside AI coding applications such as Claude Code, Gemini CLI, and VS Code. Security firms Cloudsmith and OpenSourceMalware identified the malware, which stole credentials when developers opened infected tools in their coding environments. Microsoft described the incident as a supply-chain attack targeting widely used code libraries to reach large numbers of downstream users. The breach is part of a broader wave of supply-chain compromises striking open source projects throughout 2026.

Anthropic Launches Claude Fable 5, a Publicly Available Version of Its Restricted Mythos Model
Anthropic launched Claude Fable 5, the first publicly accessible version of its Mythos model, which had been tightly restricted since April over its advanced ability to identify software security vulnerabilities. Fable 5 is designed for software engineering, knowledge work, and vision tasks, with hard safety guardrails blocking high-risk responses in cybersecurity, biology, and chemistry. Anthropic priced Fable 5 and Mythos 5 at $10 per million input tokens and $50 per million output tokens. On the SWE-bench Verified coding benchmark, Fable 5 scores 95.0 percent, topping the frontier leaderboard. Through June 22, Fable 5 is included in Pro, Max, Team, and Enterprise plans at no additional cost.
