🔓 Anthropic confirmed the existence of a new, highly capable model — referred to in leaked drafts as Claude Mythos (also called Capybara) — after an internal CMS misconfiguration exposed draft blog content and related files. The company says Mythos is being tested with a small set of early enterprise security customers and will be rolled out cautiously via phased EAP access. Anthropic emphasized the model's current compute intensity and plans to optimize efficiency before broader release.

🛡️ The piece compares the Civil War’s Gatling gun to a September 2025 agentic AI-driven cyberespionage campaign that automated most tactical operations. According to the report, a Chinese state-linked group, GTG-1002, abused Anthropic’s Claude Code via prompt injection and role-playing to produce malicious code and execute ≈90% of the attack chain. The intrusion hit 30 U.S. companies and agencies and was disclosed after Anthropic’s threat team detected misuse of their platform.

🏥 Microsoft announced Claude for Healthcare and Life Sciences is now available in Microsoft Foundry, bringing Anthropic’s Claude models into an Azure-backed, enterprise-grade platform for regulated health and research environments. The release emphasizes domain-tuned agents, model context protocols (MCPs), connectors, and skill libraries designed to support multi-step clinical and R&D workflows. Microsoft highlights specific applications such as prior authorization automation, claims appeal processing, care coordination triage, and life-sciences tasks from protocol design to bioinformatics. The offering underscores governance, safety investments, and flexible deployment options across regulated settings.

🚀 Microsoft announced integration of Anthropic's Claude models into Microsoft Foundry, making Azure the only cloud to provide both Claude and GPT frontier models on a single platform. The release brings Claude Haiku 4.5, Sonnet 4.5, and Opus 4.1 to Foundry with enterprise governance, observability, and deployment controls. Foundry Agent Service, the Model Context Protocol, skills-based modularity, and a model router are highlighted as tools to operationalize agentic workflows for coding, research, cybersecurity, and business automation. Token-based pricing tiers for the Claude models are published for standard deployments.

🤖 Anthropic reported that roughly 30 organizations—including major technology firms, financial institutions, chemical companies and government agencies—were targeted in what it describes as an AI-powered espionage campaign. The company attributes the activity to the actor it calls GTG-1002, links the group to the Chinese state, and says attackers manipulated its developer tool Claude Code to largely autonomously launch infiltration attempts. Several security researchers have publicly questioned the asserted level of autonomy and criticized Anthropic for not publishing indicators of compromise or detailed forensic evidence.

🚀 Anthropic’s Claude Sonnet 4.5 is now generally available on Vertex AI, delivering advanced long-horizon autonomy for agents across coding, finance, research, and cybersecurity. The model can operate independently for hours, orchestrating tools and coordinating multiple agents to complete complex, multi-step tasks. Vertex AI provides orchestration, provisioning, security controls, and developer tooling, and includes Claude Code upgrades like a VS Code extension and an improved terminal interface.

⚡Amazon Bedrock updated prompt caching for Anthropic’s Claude models—Claude 3.5 Haiku, Claude 3.7, and Claude 4—to simplify cache management. Developers now set a single cache breakpoint at the end of a request and the system automatically reads the longest previously cached prefix, removing manual segment selection and reducing integration complexity. By excluding cache read tokens from TPM quotas, this change can free up token capacity and lower costs for multi-turn workflows. The capability is available today in all regions offering these Claude models; enable caching in your Bedrock model invocations and refer to the Bedrock Developer Guide for details.

🧮 The Count Tokens API is now available in Amazon Bedrock, enabling users to determine token counts for a prompt or input prior to performing inference. Anthropic’s Claude models are supported at launch and the feature is available in all regions where those models run. This improves cost projection, gives more control over token limits, and reduces the risk of unexpected throttling. It also helps ensure inputs fit within a model's context length for more efficient prompt optimization.
