How Much Do You Trust A Dog? Quantifying Hint-Following in Reasoning Language Models

arXiv:2610.32055v1 Announce Type: new Abstract: Large language models (LLMs) often exhibit sycophancy, altering their answers to align with user suggestions even on objective factual and reasoning tasks. Yet the quantitative form of this influence--- and whether it is calibrated to source reliability--- remains poorly understood. In this work, we investigate this behavior through hint-induced answer shifts on MMLU questions, evaluating prompts of the form ``[Source] thinks the answer is (X)''. We systematically vary the source to which the hint is attributed (a professor, a friend, or a dog) across three open-source model families, Qwen, Gemma, and SmolLM. We show that the change induced by the hint follows a predictable structure well-characterized by an exponential tilt: the hint induces

ULME Framework Achieves True Unification of Text Embedding and Language Modeling: A New Paper on arXiv Proposes a Predictive Coupling Mechanism

On October 24, 2026, arXiv published the paper arXiv:2610.30705v1, introducing ULME—a post-training framework for causal-decoder–based large language models that, through a predictive coupling mechanism, achieves, for the first time, a mutually reinforcing unification of text embedding and language-generation capabilities. This approach was validated on the Qwen2.5/Qwen3 series (with 0.5B–8B parameters), yielding MTEB improvements of 3.3–4.1 points while maintaining performance on generation tasks such as MMLU.

Why it matters：This paper directly addresses the core issue of fragmented multimodal LLM capabilities: embeddings and generation have long been handled either by separate models or by “pseudo-unified” models that rely solely on parameter sharing. ULME achieves a substantial architectural breakthrough by employing learnable slots and joint training with three objectives—including a stop-gradient prediction loss—enabling the generation process to actively shape the embedding representations. The study features broad experimental coverage, strong baselines, comprehensive metrics, and was published on a reputable preprint platform, balancing timeliness with technical rigor.

Reflection releases the open-source large model Beam: a 501B-parameter sparse MoE architecture that supports million-token contexts and multi-level inference control.

Reflection has released the open-source large language model Beam (501B parameters, with 23B effective activations per token), which employs a 256-expert sparse MoE architecture, supports 1M tokens of context, NVFP4/FP8 quantization, multi-level inference configuration, and on-premises deployment. All technical claims have not been independently verified, hardware requirements are high, and the community generally believes that individual users will find it difficult to afford.

Qwen2.5-Max: Exploring the Intelligence of Large-scale MoE Model

QWEN CHAT API DEMO DISCORD It is widely recognized that continuously scaling both data size and model size can lead to significant improvements in model intelligence. However, the research and industry community has limited experience in effectively scaling extremely large models, whether they are dense or Mixture-of-Expert (MoE) models. Many critical details regarding this scaling process were only disclosed with the recent release of DeepSeek V3. Concurrently, we are developing Qwen2.

Towards Effective Process Supervision in Mathematical Reasoning

GITHUB HUGGING FACE MODELSCOPE DISCORD Introduction In recent years, Large Language Models (LLMs) have made remarkable advances in mathematical reasoning, yet they can make mistakes, such as miscalculations or logical errors, leading to wrong conclusions. Moreover, even when achieving correct final answers, these powerful models can still regularly make up plausible reasoning steps, where the final answers build upon flawed calculations or derivations, which undermine the reliability and trustworthiness of LLMs’ reasoning processes.
