A Reddit thread pulled attention to AISI’s latest Mythos Preview evaluation, which shows a step change not just on expert CTFs but on multi-stage cyber ranges. The important claim is not generic danger rhetoric, but that Mythos became the first model to complete a 32-step corporate attack simulation end to end.
Anthropic unveiled Project Glasswing on April 7, 2026, giving major tech and security partners access to Claude Mythos Preview for defensive vulnerability discovery. The company says the model has already found thousands of high-severity flaws and is backing the effort with up to $100 million in usage credits and $4 million in open-source donations.
Claude said on April 8, 2026 that Managed Agents lets teams define tasks, tools, and guardrails while Anthropic runs the agent infrastructure. Anthropic's official materials describe a composable API suite for cloud-hosted, versioned agents, with advanced capabilities like outcomes, memory, and multi-agent orchestration in limited research preview.
A Hacker News thread amplified a GitHub issue claiming Claude Code prompt-cache TTL behavior shifted from 1 hour to 5 minutes in early March 2026, increasing cost and quota burn.
Claude said on April 9, 2026 that Cowork is now generally available on macOS and Windows through Claude Desktop for all paid plans. Anthropic’s release notes add Analytics API exposure, usage analytics, OpenTelemetry support, and enterprise role-based access controls with SCIM groups and spend limits.
Claude said on April 9, 2026 that the advisor strategy is now in beta on Claude Platform. The new tool lets Sonnet or Haiku call Opus for planning help inside a single Messages API request, which Anthropic says raised SWE-bench Multilingual by 2.7 points while cutting cost per task by 11.9% versus Sonnet alone.
Anthropic said it has signed a new agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity that will begin coming online in 2027.
