😀A new study finds that long prompts cause a fidelity–diversity trade-off in leading T2I models: more detail but reduced diversity.
😉To evaluate this issue, the authors introduce LPD-Bench and propose PromptMoG, a training-free approach that enhances diversity by sampling prompt embeddings from a Gaussian mixture.
😉Experiments on SD3.5-Large, Flux.1-Krea-Dev, CogView4, and Qwen-Image show that PromptMoG improves long-prompt diversity without causing semantic drift.

🚀 Introducing #CompassVerifier: A unified and robust answer verifier for #LLMs evaluation and #RLVR!
��LLM progress is bottlenecked by weak evaluation, looking for an alternative to rule-based verifiers? CompassVerifier can handle multiple domains including math, science, and reasoning, as well as various answer types such as multiple-choice questions, sequences, and multiple subproblems.

🔍 Introducing #VerifierBench: A challenging dataset for evaluating the verification capabilities of different models!
🏆 Want to evaluate the verification abilities? We collected over 1 million LLMs responses using #OpenCompass framework, and selected the most challenging examples through multiple rounds of screening and manual annotation.

大语言模型具备稳定推理能力吗？

「来自上海 AI 实验室 @OpenCompassX 的研究，通过创新的评估方法揭示了一个关键问题：尽管大语言模型在单次测试中可能表现出色（如 OpenAI 最新模型单次准确率达 66.5%），但在需要持续稳定输出的场景中，几乎所有模型的表现都会大幅下降（降幅普遍超过 60%），这说明当前 AI 模型的"思考能力"仍不够稳定和可靠」

论文目前在 HF Papers 当日排名居首位，关注度很高 @_akhaliq 👍

一、��究背景和问题

· 虽然大语言模型在数学推理等复杂任务上表现优秀，但基准测试成绩与实际应用效果存在差距
· 现有评估方法无法真实反映模型在实际应用中的稳定性

二、主要创新

· G-Pass@k评估指标：评估模型在多次尝试中保持正确答案的能力
· LiveMathBench测试集：收集最新���学竞赛题目，确保评估的时效性和难度

三、关键评测发现

· 通用大模型表现
- Gemini-1.5-Pro表现最佳：单次测试49.2%，但在严格标准下降至26.8%
- GPT-4和Claude-3.5表现相近：单次成绩约40%，严格测试均降至20%以下

· 数学专用模型表现
- Qwen2.5-Math-72B潜力最高：单次可达50.4%，但稳定性测试降至26.8%
- 其他专用模型表现不佳：DeepSeek-Math和NuminaMath在严格测试中均低于6%

· o1系列模型亮点
- OpenAI o1-mini最为稳定：单次66.5%，严格测试仍保持42.0%
- QwQ-32B紧随其后：严格测试保持33.3%的水平
展现出更好的推理稳定性

四、核心启示

· 稳定性挑战
- 几乎所有模型在严格测试下表现显著下降
- 平均性能衰减超过60%
- 即使是专门优化的数学模型也难以保持稳定表现

· 规模效应局限
- 增加模型参数量并不能显著提升推理稳定性
- 如72B和32B版本的Qwen模型表现相近

· 未来方向
- 需要更注重模型的稳定性而非单次表现
- o1系列的架构创新可能提供了提升稳定性的新思路
- 评估方法需要更贴近实际应用场景
