Model releases, architecture work and prompting research on large language models — from frontier-lab announcements to the arXiv papers behind them.

The paper introduces a Voice Retention / Representation Ratio metric to assess bias in large language model (LLM) summaries of employee feedback. Using a bilingual corpus of 2,586 responses from a global professional services firm, the study finds that criticism is reported more reliably than praise, and that LLM summaries tend to filter by popularity rather than sentiment—criticism often survives while single-mention concerns, short or German-only content are frequently omitted. The authors argue that prevalence, not sentiment, drives the bias, and provide a metric, field evidence, and a disaggregated voice‑retention card for future audits.

The paper introduces FIGS, a dual‑axis evaluation framework for multi‑turn sycophancy that avoids penalizing empathy. It uses a 10‑turn conversational simulator with 500 diverse scenarios to test whether models stay truthful while keeping praise proportional, and whether they show calibrated validation of user feelings. The study finds that current models either drift toward sycophancy or become overly detached, highlighting an unresolved trade‑off in sustained dialogue.
arXiv:2609.39920v1 Announce Type: cross Abstract: Large vision-language models (LVLMs) exhibit strong multimodal in-context learning (ICL) capabilities, yet this ability degrades substantially as mod...

The paper proposes that large language models (LLMs) encode high‑level concepts as linear directions within their activation space and that they can use subspaces and vector algebra to perform tasks. By analyzing functional modules and residual streams during in‑context learning (ICL), the authors find that LLMs can create evidence‑accumulating subspaces and solve ICL tasks through simple algebraic operations within those subspaces.

The paper presents an LLM-based framework for automatically classifying crisis levels in psychological support hotlines, addressing variability in human judgments and staffing constraints. It introduces a paralinguistic injection method that embeds non‑verbal emotional cues into transcripts, allowing the model to consider acoustic nuances. A reasoning‑enhanced training strategy encourages the model to produce diagnostic reasoning chains, which regularizes and improves classification, achieving a macro F1‑score of 0.802 and accuracy of 0.805 in 5‑fold cross‑validation.
