    Anthropic Refunds Claude Code Users After 'HERMES.md' Commit Strings Silently Drained Quotas
    • Substring match in Claude Code's harness-detection logic routed any session whose recent git history contained 'HERMES.md' to extra-usage billing instead of plan quota.
    • One Max-20x user lost $200 in overage credits while plan usage was still at 13%; charges occurred silently with no UI warning.
    • GitHub issue anthropics/claude-code#53262 traces the bug to the wider crackdown on third-party agent harnesses (Hermes, Codex CLI, Goose).
    • Hit HN front page at 828 points; refunds plus $200 in credits issued ~9 hours later. Discussion: HN item 47948012.

    OpenAI Begins GPT-5.5-Cyber Rollout — Then Quietly Adopts Anthropic's Restricted-Access Model
    • Sam Altman: rollout 'to critical cyber defenders in the next few days' via the expanded Trusted Access for Cyber (TAC) program.
    • TAC scaled to thousands of vetted defenders across government, critical infrastructure, security vendors, cloud platforms, and financial institutions.
    • TechCrunch headline of the day: 'After dissing Anthropic for limiting Mythos, OpenAI restricts access to Cyber, too' — Altman called the same approach 'fear-based marketing' two weeks ago.
    • No technical card or benchmarks against Mythos published; positioned as a fine-tuned GPT-5.5 with relaxed guardrails for security work.

    • Pivot from a B2B production library to a consumer app that streams, remixes (genre/tempo), and generates from lyric/melody/mood prompts.
    • Free tier caps at 7 songs/day; Pro at $9.99/mo unlocks 500 generations/mo; positioned as 'fully licensed, artist-first by design.'
    • Roughly 4,000 mostly-emerging human artists onboarded with revenue share; direct shot at Suno and Udio amid mounting label lawsuits.
    • Launch coincides with Taylor Swift's legal team filing on AI music likeness — TechCrunch frames the consumer pivot as the bet that licensing wins this round.
