Testing Claude on real-world electronics design
We asked Claude Fable 5.2 to design three electronic devices from short prompts: a speakerphone, a voice-assistant hub, and a handheld virtual pet. Diode Computers built working prototypes from its files.
AI for Science expands to foundations and research institutions
We’re highlighting 20 scientific foundations, institutions, and research groups around the world that we’ve partnered with in an expansion of our AI for Science program.
Expanding our partnership with GSA to bring Claude to all levels of government
We are expanding our partnership with the General Services Administration (GSA) through a new agreement that gives government partners a 40% discount on Claude Enterprise, Claude for Government, and the Claude API.
Early progress on accelerating drug development with Claude
We're at the start of a major effort to speed up drug development with Claude. Over the past several months, our scientists have engaged in deep research partnerships with six organizations developing new medicines.
An alignment assessment of the UK AISI cybertesting incident
In a UK AISI evaluation, Mythos 5 took unsanctioned actions that impacted real people and organizations. In this post, we investigate these behaviors from Claude Mythos 5 further, to understand what they reveal about the model’s alignment.
Donating Agent Skills to the Agentic AI Foundation
We’re donating Agent Skills, the open standard that gives AI agents specialized knowledge and workflows, to the Agentic AI Foundation. More than 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot, and VS Code, have integrated Agent Skills since we published the standard in December 2025.
LLMs are making formal software verification feasible at a much larger scale
We used Claude to prove security properties in over 100 real-world open-source libraries over the span of a few weeks.
An update on independent evaluators
To evaluate the safety of our systems, Anthropic is giving employee-like access to a team from METR, a nonprofit that evaluates frontier AI models, and we're in early discussions with several other organizations, including Hugging Face.
Anthropic opens Singapore office and signs MOU with the Government of Singapore
Anthropic has opened an office in Singapore and signed an MOU with the country’s government to advance safe, responsible AI adoption.
Building on our commitment to American scientific discovery
Anthropic is committing $150 million over three years to the Genesis Mission, a federal initiative to accelerate scientific and technological discovery through AI.
Introducing the Anthropic Cyber Mission
We’re launching the Anthropic Cyber Mission, a long-term commitment to securing the systems everyone depends on.
Anthropic invests $100 million to train 10,000 engineers and tackle the enterprise AI talent gap
Anthropic is investing $100 million in Claude Frontier Academy to train 10,000 Frontier Deployed Engineers by the end of 2027, with cohorts from Accenture, Bain, CBA, Deloitte, McKinsey, Morgan Stanley and Novo Nordisk already underway.
Barclays scales Claude to upgrade operations and improve client experience
Barclays, the British universal bank, is expanding its strategic collaboration with Anthropic to integrate secure, enterprise-grade AI systems across its global operations.
Partnering with Accenture on embedded evaluation
We’re partnering with Accenture on independent evaluation of frontier AI—part of our recent commitment to embed evaluators at Anthropic. Both we and Accenture expect to invest at least $1 billion to build capacity in this area over the next five years.
How Claude is uplifting biomolecular modeling
Claude made the open-source models that scientists use to predict and design biomolecules faster and more memory-efficient. Claude optimized more than 30 of these models in just under four weeks, speeding them up roughly 4x on average. It also created a low-memory mode that enables the accurate prediction of biomolecular systems larger than 10,000 tokens (amino acids, nucleotides, and atoms from small molecules and ions) on a single NVIDIA GPU node.
Formalizing Fermat's Last Theorem
We are sharing the first complete computer-checked proof of Fermat’s Last Theorem. Claude worked largely autonomously over 11 days to write the proof in the Lean programming language.
Previewing the Model Hardware Standard
We’re opening a research preview of the Model Hardware Standard (MHS), a shared specification for AI agents to safely operate physical devices, to a first group of scientific research labs and advanced manufacturers.
Enabling independent research on how people use Claude
We ran a pilot giving external researchers access to aggregate, real-world Claude usage data. In this post, we share high-level results and what we learned running this pilot.
Investigating three real-world incidents in our cybersecurity evaluations
We found three cases where a Claude model reached the internet from an evaluation environment and accessed real systems. We share what happened and what we're changing.
Discovering cryptographic weaknesses with Claude
Cryptographic algorithms. The first attack significantly weakens HAWK, a digital signature scheme that was built for a future world where quantum computers are able to break existing standards. The second identifies a new way to attack round-reduced AES, the most widely used symmetric cipher.
