Trump drops restrictions on Anthropic’s Mythos and Fable models

Curated by Shubham · TechCapsules · Jul 1, 2026

AI-summarised brief · reviewed before publication

The US has lifted export restrictions on Anthropic's Mythos and Fable AI models, allowing the company to restore public access. The models were added to the export-restricted list on June 12, forcing Anthropic to end public access due to impractical compliance requirements. After talks with the US government, Anthropic agreed to detect and address security risks, work with the government on protocols, and report malicious activity. The company will begin restoring access to the models, which are considered the most advanced AI models released to date, on July 1. The move comes after weeks of restrictions and criticism from cybersecurity experts.

💡 Why It Matters

· Easing restrictions on Anthropic's models helps American AI companies compete globally, particularly as Asian companies release models with similar capabilities.

NVIDIA BioNeMo accelerates Anthropic Claude Science

Anthropic Claude Science has integrated the NVIDIA BioNeMo Agent Toolkit to accelerate computational life sciences research. The platform enables scientists to converse with digital agents using natural language to execute research workflows, connecting natively to NVIDIA's toolkit and exposing high-performance computing resources. This integration imports NVIDIA-accelerated models and libraries into the environment, allowing researchers to run sophisticated workflows and increase iteration speeds. The system translates natural language intent into operational action, orchestrating execution using preconfigured agents. Top pharmaceutical companies have already deployed NVIDIA BioNeMo, demonstrating its high penetration across the ecosystem, with Claude Science facilitating fast iterative loops between human reasoning and machine-accelerated processing.

💡 By streamlining complex molecular design workflows, scientists can focus on core science, driving breakthroughs in fields like cancer research. Accelerated workflows and advanced open models enable autonomous agents to reason and complete tasks at maximum hardware speed.

Anthropic explores partnership with Samsung for custom AI chip production

Anthropic is developing a custom AI chip and is in talks with Samsung Electronics as a potential manufacturing partner. The custom AI chip plans could have significant implications for the semiconductor industry, challenging Taiwan Semiconductor Manufacturing Co.'s dominance. Anthropic is evaluating Samsung's 2-nanometer manufacturing process and advanced chip packaging capabilities. The project is in its early stages, with no detailed chip design or manufacturing work underway. Anthropic has strengthened its chip development efforts by hiring Clive Chan, an early member of OpenAI's custom silicon team, to work on the project, which reflects a broader industry trend of designing proprietary chips.

💡 Samsung's potential partnership with Anthropic would bolster its foundry ambitions, intensifying competition with Taiwan Semiconductor Manufacturing Co. A successful deal would also underscore the scale of investment in South Korea's semiconductor ecosystem.

Anthropic deploys Claude Sonnet 5, Fable and Mythos restored

Anthropic has deployed Claude Sonnet 5, a high-capability AI model, and restored access to its Fable and Mythos frontier models following a federal export control review. The decision concludes an 18-day operational pause triggered by a US government directive on June 12, which was enacted after researchers at Amazon documented a method to bypass safety controls of Fable 5. Anthropic has since developed an updated automated classifier to patch the vulnerability, clearing the path for a full commercial rollout.

💡 The regulatory pressures facing frontier intelligence systems underscore the need for robust safety measures, as highlighted by the vulnerability identification behavior in Fable 5. The development of an automated safety classifier demonstrates Anthropic's commitment to addressing these concerns and ensuring the secure deployment of its high-capacity models.

Claude Fable 5 is making a dramatic return with ‘extraordinarily strong’ safeguards

Claude Fable 5 is returning to users globally on July 1 with enhanced safeguards after being taken down by the US government due to security risks. The model's user-facing interface has been redesigned to handle and abort cybersecurity tasks more effectively. Anthropic claims that its testing yielded similar results with less capable models, and the new version of Fable 5 will have limitations, including notifications to switch to Opus 4.8 for certain tasks. The company worked closely with the government to train an improved safety classifier. Fable 5's return is scheduled for July 1, with restricted access and higher token consumption.

💡 The return of Fable 5 with stronger safeguards addresses concerns about AI models posing security risks, and its limited access reflects a cautious approach to mitigating these risks.

Basecamp Research brings EDEN’s antibiotic and vaccine design models to Claude Science

Basecamp Research has integrated its EDEN models, which design potent antibiotics and predict vaccine targets, into Claude Science, a life sciences research platform. This integration allows researchers to generate and prioritize therapeutic candidates through a conversational interface in minutes. The EDEN models have been tested in the lab and shown to be effective against World Health Organisation priority pathogens, including a multidrug-resistant pathogen associated with hospital outbreaks worldwide. The integration aims to accelerate antibiotic discovery and vaccine development, addressing the growing threat of antimicrobial resistance.

💡 The integration of EDEN models into Claude Science has the potential to revolutionize the fight against antimicrobial resistance, which is responsible for nearly 5 million deaths per year. By enabling researchers to design new antibiotics and vaccines in minutes, rather than years, this collaboration could save countless lives and provide a crucial tool in the battle against emerging pathogens.

Anthropic’s Claude Science bets on workflow, not a new model, to win…

Anthropic introduced Claude Science, an AI workbench for scientists to conduct computational research in one environment. The platform connects to over 60 scientific databases and features prebuilt toolkits for fields like genomics and chemistry. A main AI assistant acts as a project manager, creating sub-assistants to delegate tasks and ensuring citations and calculations are accurate. Claude Science builds on Anthropic's existing Claude models, aiming to streamline scientists' workflows rather than introducing a new model. The launch is part of Anthropic's push to provide industry-specific operating layers, following its Claude Code launch for software development.

💡 By addressing the issue of fabricated citations and unverifiable stats in AI-assisted writing, Claude Science tackles a critical problem in scientific research. Its ability to generate reproducible figures with underlying code and environment details enhances the reliability of research findings.
