Why: If your agentic coding setup relies on the assumption that the model cannot write working memory-corruption exploits, that assumption no longer holds for at least two models named here (GLM-5.3, Claude Mythos Preview), while the prior generation (GLM-5.2, Opus 4.6) scored zero.

Quoting Anthropic Frontier Red Team
