ProxyFormer reduces transformer attention cost for long context and high-resolution generation

ProxyFormer addresses a fundamental scaling constraint in modern transformers: the quadratic memory and compute cost of attention as context length and image resolution grow. The architecture compresses fine-grained features into proxy tokens at each layer, performs expensive global computations only on this compressed representation, then decompresses results back into the full feature stream. By preserving the local stream across layers, the method avoids irreversible information loss that plagues conventional compression schemes. This dual-stream design could unlock practical ultra-long-context models and high-resolution generation without the prohibitive KV cache overhead that currently limits deployment, making it strategically relevant for both language and vision model scaling.

LLM value measurement methods show inconsistent preference signals across tasks

STONIC exposes a fundamental crack in how researchers measure LLM values and preferences. By testing 35 model configurations across 5,144 scenarios, the study reveals that questionnaires, pairwise choices, and spontaneous text generation do not measure the same underlying preference, contradicting a core assumption in value alignment work. Most critically, models consistently favor their own prior outputs over alternatives, and choice patterns shift based on option ordering, suggesting that current value profiling methods may be capturing behavioral artifacts rather than stable preferences. This finding directly challenges the validity of value datasets used to train and evaluate alignment in production systems.

New regularization method decouples LLM exploration from output constraints

Researchers propose Environment-Regularized Policy Optimization (ERPO), a technique that reframes how language models balance exploration and stability during reinforcement learning training. Rather than constraining model outputs directly, ERPO shifts regularization to the input side by tracking query distribution drift from a reference dataset. This addresses a fundamental tension in policy optimization: standard KL penalties on actions limit both exploration and response diversity, while removing them leaves training unmoored. The approach matters because it could unlock more efficient RL fine-tuning for LLMs, allowing practitioners to explore richer behaviors without sacrificing training stability or requiring careful hyperparameter tuning between competing objectives.

Sigmoid attention enables practical learned KV-cache eviction in transformers

Researchers demonstrate that sigmoid attention functions unlock a practical pathway for learned KV-cache eviction in transformers, resolving a long-standing training-inference gap. During training, differentiable gating typically softens token importance scores, but inference requires hard deletion to save memory. This work shows sigmoid attention shifts the operating point such that learned gates can now delete cache entries with minimal perplexity degradation. The finding matters for production LLM inference: it suggests attention substrate choice directly influences memory optimization feasibility, potentially enabling more aggressive cache compression without sacrificing model quality. For practitioners optimizing inference cost, this opens a concrete lever beyond standard attention mechanisms.
