TurboPairFormer: Fast and Stable Protein Folding Model Training with an Optimized Triangle Attention Kernel

Triangular attention is a core computation in AlphaFold3-style biomolecular models, with cubic cost in token count. Its shared pair bias adds a gradient reduction across attention slices to the usual reductions over queries and keys. The open-source backends we examine handle these reductions through repeated probabili...

Adaptive Adversaries: A Multi-Turn, Multi-LLM Benchmark for LLM Agent Security

A 21-scenario benchmark for adaptive cross-session attacks against fresh-session LLM defenders is presented: an autonomous LLM attacker observes prior defender responses and pivots across rounds, while each defender response is evaluated as a fresh interaction.
