Model behavior, misuse, alignment research, and public incidents. The slow-cycle, high-stakes category. Covered with honest severity assessments and a builder question: does this change what you should or shouldn't be putting into a model prompt this week?
GPT-Rosalind launched in April 2026 for pharma research, topping the BixBench bioinformatics benchmark at 0.751 Pass@1. On May 29, OpenAI extended it to US government biodefense partners including Lawrence Livermore National Laboratory and CEPI. The benchmark holds. The governance structure is more restricted than anything OpenAI has shipped before.
Anthropic's initial update on Project Glasswing is out: Claude Mythos Preview found over 10,000 high- and critical-severity zero-days in one month across every major OS and browser. It's an extraordinary number. The bottleneck is now patching.
The Intent Laundering paper achieves 90-100% jailbreak success against Gemini 3 Pro and Claude under black-box access. Current safety evaluations failed to predict this. The lesson isn't 'these models are broken.' It's that we've been evaluating the wrong thing.
Anthropic and OpenAI ran simultaneous alignment evaluations against each other's models earlier in 2026 — a first for the industry. Four areas tested: instruction hierarchy, jailbreaking resistance, hallucination prevention, scheming behavior. The findings deserve attention. So does the precedent.
