Claude 'Oceanus' model identifier appears in Claude Console
A new model identifier — claude-oceanus-v1-p — appeared in the Claude Console with red-team access granted around the same day. Oceanus appears to be the next preview candidate in the Mythos line, focused on agentic coding + offensive security rather than chat. Red-team-to-launch lag has been 1-2 weeks historically — possible public launch second half of June.

Security researcher finds 4-year-old Zcash ZK proof bug with Claude Opus 4.8
Independent researcher Taylor Hornby discovered a critical soundness bug in Zcash's Orchard circuit that allowed unlimited counterfeit ZEC minting inside the shielded pool. The exploit was written using Anthropic's publicly available Opus 4.8 — not the Glasswing-gated Mythos. ZEC dropped 31% intraday before partial recovery.

Claude Security launches in public Enterprise beta — runs on Opus 4.7
Anthropic's Claude Security product entered public Enterprise beta, reporting 2,100+ vulnerabilities patched in three weeks. Important detail: the production product runs on Opus 4.7, not Mythos. The 'Mythos 1' toggle that briefly appeared in the UI is a placeholder for future Mythos-class capability — not active production.

Cursor 3.0 ships — Agents Window, /worktree and /best-of-n commands
Cursor 3.0 reframed the IDE around the Agents Window — run many agents in parallel across local repos, git worktrees, cloud VMs, remote SSH.
