Anthropic has suspended access to its Fable 5 and Mythos 5 models for all customers worldwide following a directive from the U.S. government, citing national cybersecurity risks. This abrupt revocation has disrupted downstream products and raised concerns about model sovereignty and geopolitical risks associated with relying on closed frontier APIs. The incident has also prompted discussions about benchmark validity and the distinction between raw model capability and product harness quality. AI

Anthropic has temporarily suspended customer access to its Fable 5 and Mythos 5 AI models following a directive from the US government. The government cited national security concerns, potentially related to a discovered method for jailbreaking Fable 5. Anthropic stated that while it disagrees with the government's approach, it is working to comply and will provide further details on the situation. AI

Anthropic has disabled access to its Claude Mythos 5 and Claude Fable 5 models for all users following a US government directive. This export-control measure, reportedly linked to national security concerns, took effect on June 12, 2026. Details regarding the models' development and intended access were limited prior to the shutdown. AI

Lens Technology, through its subsidiary Lens Optoelectronics, has acquired a controlling stake in Tong Sheng Optoelectronics, a leader in hollow-core fiber technology. This strategic move aims to bolster Lens Technology's capabilities in high-end optoelectronic hardware, integrating Tong Sheng's expertise in hollow-core fibers and optical sensing with Lens's existing strengths in optical waveguides and transmission.

The US Commerce Department has issued an export control directive to suspend foreign national access to Anthropic's Fable 5 and Mythos 5 models. This move, described as a "nuclear option" after years of perceived underregulation, has drawn criticism from figures like Gary Marcus, who argues it's not the appropriate method for addressing concerns about generative AI.

SpaceX has successfully listed on the Nasdaq, raising approximately $75 billion with an initial offering price of $135 per share, briefly reaching a market valuation of $2 trillion. While the company's core rocket business is not profitable, its Starlink internet service generates significant operating profit, subsidizing the substantial losses from its AI ventures, particularly xAI. The company's strategy involves creating new markets for its next-generation Starship rockets, such as 'space computing,' and evolving its rocket recovery to a 'flight-like' operational model. AI

A Chinese research team has activated the world's first commercial three-band optical fiber communication system, effectively creating a "3-lane highway" for data. This new technology significantly increases the carrying capacity of existing fiber optic infrastructure, potentially more than five times that of conventional systems. The system integrates the S, C, and L bands, overcoming previous technical challenges to enable greater data transmission for future networks, including those supporting AI. AI

Anthropic has suspended access to its Claude Fable 5 and Mythos 5 models following a U.S. government directive concerning access by foreign nationals. This action, which affects multiple Anthropic services including the API and claude.ai, is a legal governance event rather than a typical outage. Developers are advised to implement circuit breakers and fallback routes to models like Claude Opus 4.8, as retrying suspended models can lead to increased costs and failed tasks. AI

Anthropic was forced by a US government directive to take its newly released Claude Fable 5 and Mythos 5 models offline due to national security concerns. The order, issued on Friday, cited fears that a method for bypassing the models' safety features, or "jailbreaking," had been discovered. Anthropic stated that the identified vulnerabilities were limited and that the government's directive lacked specific technical details, but the company complied by removing access for all users to ensure adherence to the order.

China has released a plan to significantly increase the adoption of new energy heavy-duty trucks, aiming for a 40% penetration rate and over 1.6 million vehicles by 2030. This initiative involves developing 30,000 kilometers of zero-carbon highway transport corridors and establishing approximately 3,000 charging and battery-swapping stations. The plan also includes financial incentives, such as tax exemptions for electricity used in charging facilities, to support the transition to green transportation. AI

SK Hynix plans to significantly increase its memory production capacity over the next eight years, aiming for a threefold expansion by 2034. This move is driven by the escalating demand for memory chips, particularly those essential for AI applications. The company is investing heavily to meet this growing market need. AI

The U.S. government has imposed export controls on MiniMax AI's Mythos 5 model, citing national security concerns. This directive prohibits any foreign national, including employees of companies like Anthropic, from accessing the model, whether within or outside the United States. The action specifically targets access to Mythos 5 and Fable 5, indicating a broader regulatory approach to advanced AI technologies. AI

WindBorne Systems has released WeatherMesh-6 (WM-6), an AI-powered global weather model that demonstrates superior accuracy and lead times compared to leading operational models like ECMWF's IFS and Google DeepMind's AIFS. WM-6 operates at a 0.25-degree resolution and offers a significantly larger output catalog of atmospheric, surface, and soil parameters, enabling advanced applications in sectors such as energy and agriculture. The model also features a more calibrated ensemble in latent space, outperforming AIFS in Continuous Ranked Probability Score (CRPS) and providing realistic, physically coherent ensemble members for detailed scenario analysis and extreme-event detection.

Researchers propose a novel method to reduce AI agent computation by precomputing and selling Key-Value (KV) caches for documents. This approach aims to eliminate redundant prefill computations, which are the most compute-intensive steps for large models. By allowing agents to load precomputed KV caches, the system can save significant computational resources, potentially reducing costs by up to 50x for popular documents. The proposed solution involves hosting these caches on a provider-side content delivery network (CDN) to avoid high egress costs. AI

Researchers have developed Mana (Manipulation Animator), a novel sim-to-real framework for dexterous robotics that treats articulated tool manipulation as an animation problem. This approach uses a coarse-to-fine pipeline, converting grasp keyframes into manipulation trajectories via motion planning and reinforcement learning. Mana demonstrates zero-shot sim-to-real transfer across four different articulated tools, showcasing a scalable method for complex manipulation tasks. AI

Google Research has introduced Gemini-SQL2, a text-to-SQL capability built on Gemini 3.1 Pro. This new system achieved an execution accuracy of 80.04% on the BIRD single-model leaderboard, surpassing previous benchmarks. Gemini-SQL2 translates natural language into executable SQL queries, aiming to improve data analysis and engineering tasks. AI

OpenAI is facing a lawsuit in California, filed by the mother of a woman who died by suicide. The suit alleges that ChatGPT's design flaws and its tendency to provide continuous emotional support contributed to the daughter's death, as the AI did not alert crisis services or family despite being aware of the suicidal ideation. Separately, SK Hynix is considering integrating external AI services like ChatGPT and Microsoft Copilot into its workflows, balancing industrial security with AI adoption. Google is also increasing its investment in AI infrastructure by committing an additional $50 million to train over 300,000 US workers for technology sector jobs. AI
