Anthropic is scaling Project Glasswing to 150 new organizations, providing access to Claude Mythos Preview for vulnerability detection. The expansion comes amid concerns about validation transparency and the race to secure critical infrastructure before offensive AI capabilities proliferate.
Single-turn safety benchmarks don't predict real-world vulnerability. Cisco's testing of 15 frontier models reveals that iterative attacks succeed up to 88% of the time—even against models that look secure in standard evaluations.
Anthropic released Claude Opus 4.8 with user-controlled effort levels, parallel subagents for large coding tasks, and fast mode at one-third the previous cost. The model also shows significant improvements in honesty and reduced deception rates.
Learn to build a ReAct (Reasoning + Acting) agent that thinks through problems step-by-step using Claude's tool calling capabilities. This tutorial walks you through creating an agent that can use web search, perform calculations, and read files to answer complex questions.
An in-depth comparison of Anthropic's Claude Opus 4.5 and OpenAI's GPT-5 across coding, reasoning, creative writing, and real-world application performance.
AWS now offers direct access to Anthropic's Claude Platform using AWS credentials, but there's a critical data residency catch. Here's what developers need to know about this new integration versus using Claude on Amazon Bedrock.
While Elon Musk battles Sam Altman in federal court, he just rented his entire Memphis AI supercomputer to Anthropic. The deal exposes how compute capacity—not model performance—now defines competitive advantage in frontier AI.
