Key Highlights

  • OpenAI launched GPT-5.4-Cyber, a defensive security model taking the opposite approach to Anthropic’s Mythos — expanding access to thousands of verified defenders rather than restricting to ~40 trusted partners
  • Anthropic’s revenue surge is rattling OpenAI investors, with annualized revenue jumping from $9B to $30B in three months, making Anthropic’s $380B valuation look attractive next to OpenAI’s $852B
  • Anthropic briefed the Trump administration on Mythos despite simultaneously suing the DoD, framing the Pentagon dispute as a “narrow contracting dispute” separate from national security collaboration
  • Apple is aggressively blocking vibe-coding apps from the App Store, hitting Replit, Vibecode, and Anything — citing rules against apps that download and execute code
  • Google shipped AI Skills in Chrome, letting users save and reuse custom Gemini prompts across websites

Analysis & Opinion

OpenAI’s GPT-5.4-Cyber rejects Mythos playbook — Rundown

OpenAI introduced GPT-5.4-Cyber, a defensive security model that directly challenges Anthropic’s restricted-access approach with Mythos. While Anthropic limits access to ~40 trusted partners, OpenAI is expanding availability through its Trusted Access for Cyber initiative, granting access to thousands of verified defenders after identity verification. The model enables reverse-engineering of compiled software to detect malware without source code. OpenAI researcher Fouad Matin framed cyber defense as a “team sport,” arguing no company should pick winners and losers in who accesses these tools.

Anthropic’s rise is giving some OpenAI investors second thoughts — TechCrunch

OpenAI’s $852B valuation is drawing skepticism from its own investors as Anthropic’s annualized revenue surged from $9B to $30B in three months, driven primarily by coding tool demand. Secondary markets reflect the shift — Anthropic shares see strong demand while OpenAI trades at a discount. One investment firm president called OpenAI “the Netscape of AI,” referencing the once-dominant browser that lost market position and was eventually absorbed.

Anthropic co-founder confirms the company briefed the Trump administration on Mythos — TechCrunch

Jack Clark confirmed Anthropic briefed the Trump administration on Mythos, the unreleased model with powerful cybersecurity capabilities that prompted Treasury Secretary Bessent to convene an emergency Wall Street briefing. Clark characterized the concurrent DoD lawsuit as a “narrow contracting dispute” and emphasized national security concerns shouldn’t prevent government collaboration.

How vibe-coding app Anything is rebuilding after getting booted from the App Store twice — TechCrunch

Apple is systematically blocking vibe-coding apps from the App Store, impacting Replit, Vibecode, and Anything — the latter removed twice. Apple cites developer agreement clause 2.5.2, which prohibits apps from downloading, installing, or executing code. Anything’s co-founder says updates worked fine through December before a blanket enforcement shift hit the entire category. The company is now pivoting to a desktop companion tool.

Max Hodak’s Science Corp. is preparing to place its first sensor in a human brain — TechCrunch

Science Corporation, founded by former Neuralink president Max Hodak, recruited Yale neurosurgery chair Dr. Murat Günel to oversee its first human brain sensor implant. The company’s approach uses biological neural connections rather than metal probes, which Günel argues avoids the tissue damage that undermines long-term BCI performance. Fresh off a $230M Series C ($1.5B valuation).
