Updates from OpenAI / Anthropic / Google. This issue is mainly a roundup of "recent verifiable developments" (dates noted); no major new product releases today. 🛡 = security-related.
OpenAI
- Safety Bug Bounty (launched 2026-03): a dedicated "safety" bounty program operated via Bugcrowd, with an annual pool of about $1M, separate from the existing Security Bug Bounty. Scope includes prompt injection, guardrail jailbreaks, training-data leakage, agentic/MCP risks, account and platform integrity, and the OWASP LLM Top 10. (source)
- Open-source models gpt-oss-120b / 20b: the 120b runs on a single GPU and the 20b runs locally on high-end consumer laptops, lowering the barrier to local inference. (source)
Anthropic
- Claude Mythos 1 / Project Glasswing: the next-generation model and preview program continued advancing through H1 2026 (the Project Glasswing preview has been rolling out to a small circle since 2026-04-07). (source)
- Claude-assisted vulnerability discovery: in 2026-03 FreeBSD published CVE-2026-4747 (RPCSEC_GSS RCE), crediting "Nicholas Carlini using Claude, Anthropic"; on 2026-04-03 NVD published CVE-2026-31402 (Linux kernel NFS replay-cache heap overflow), publicly linked to Claude-assisted discovery — AI-assisted vulnerability research has moved into real-world practice. (source)
Google DeepMind / AI
- Gemini 3.5 Pro / 3.5 Flash: 3.5 Flash went GA at Google I/O 2026 (2026-05-19); 3.5 Pro is advancing in parallel. (source)
- AlphaEvolve expansion: its impact extends into genomics, quantum physics, mathematics, AI infrastructure, and commercial applications (DNA sequencing error correction -30%, quantum-circuit error down 10x). (source)
Security Takeaways
- OpenAI Safety BB + HackerOne AI vulnerabilities up 210% year over year (prompt injection at the top): AI bounties are the fastest-growing security track right now.
- Claude-assisted discovery of real FreeBSD / Linux kernel CVEs: LLMs can now produce verifiable results in kernel-level vulnerability research— both offense and defense need to reassess.
