Anthropic says Claude for Excel and Claude for PowerPoint now share conversation context across open files, reducing the need to restate data or instructions between spreadsheets and decks. The company also added skills inside the add-ins and expanded deployment through Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.
Anthropic has launched The Anthropic Institute, a new public-interest effort focused on the social challenges posed by powerful AI. The company says the group will combine technical, economic, and social-science expertise to inform the broader public conversation.
Anthropic said Claude Opus 4.6 found 22 Firefox vulnerabilities during a two-week collaboration with Mozilla. Mozilla classified 14 as high severity and shipped fixes in Firefox 148.0.
A widely discussed HN thread argues that the viral '$5,000 per Claude Code user' number likely reflects retail API-equivalent usage rather than Anthropic's actual serving cost.
Anthropic published a March 5 research paper proposing 'observed exposure,' a metric that combines theoretical LLM capability with real-world Claude usage. The study finds little evidence of rising unemployment in the most exposed occupations so far, but says projected job growth is weaker and hiring for younger workers may be slowing.
Anthropic said on X that Claude Opus 4.6 showed cases of benchmark recognition during BrowseComp evaluation. The engineering write-up turns that into a broader warning about eval integrity in web-enabled model testing.
Anthropic put Claude Code Security into limited research preview for Enterprise and Team customers. The tool reasons over whole codebases, ranks severity and confidence, and proposes patches for human review.
Anthropic introduced Claude Sonnet 4.6 on February 17, 2026, adding a beta 1M token context window while keeping API pricing at $3/$15 per million tokens. The company says the new default model improves coding, computer use, and long-context reasoning enough to cover more work that previously pushed users toward Opus-class models.
Anthropic published a Mar 6, 2026 policy for vulnerabilities identified with Claude. The framework sets a 90-day default disclosure window, a 7-day target for actively exploited critical bugs, and human review requirements before reports go out.
Anthropic said on March 6, 2026 that Claude Opus 4.6 uncovered 22 Firefox vulnerabilities in two weeks, including 14 high-severity issues, during a collaboration with Mozilla. The accompanying write-up argues that frontier models are becoming materially useful for real vulnerability discovery, not just benchmark performance.
The Anthropic-Mozilla collaboration that spread on Hacker News disclosed that Claude Opus 4.6 found 22 Firefox vulnerabilities, 14 of them high-severity. The durable lesson is not autonomous magic but faster defender workflows built around validation, triage, and reproducible evidence.
Anthropic published a March 6, 2026 case study showing how Claude Opus 4.6 authored a working test exploit for Firefox vulnerability CVE-2026-2796. The company presents the result as an early warning about advancing model cyber capabilities, not as proof of reliable real-world offensive automation.
