ConceptCLIP is evaluated across 52 clinical tasks spanning 10 imaging modalities. It performs strongly in zero-shot diagnosis, retrieval, VQA & report generation, while providing concept-level explanations that clinicians can inspect and validate. 3/4

HKUST Develops Novel AI Framework Enabling Efficient Collaboration between Generalist and Specialist Models for Disease Diagnosis A research team from HKUST has developed a novel AI framework, the Generalist–Specialist Collaboration (GSCo), which enables a generalist foundation model and specialist models to collaborate on disease diagnosis. GSCo outperforms both standalone models in tasks such as medical imaging, visual question answering, and radiology report generation, while significantly reducing development costs of medical models to adapt to new clinical tasks. This marks a meaningful step toward bringing AI medical models into everyday clinical workflows. The study, titled "Towards generalizable AI in medicine via Generalist–Specialist Collaboration," was published in the prestigious academic journal Nature Biomedical Engineering. The GSCo framework was developed by a research team led by Prof. CHEN Hao, Assistant Professor of the Department of Computer Science and Engineering and the Department of Chemical and Biological Engineering and Director of the Collaborative Center for Medical and Engineering Innovation, in collaboration with Harvard Medical School, Weill Cornell Medicine, The Chinese University of Hong Kong, The University of Hong Kong, Sun Yat-sen University and other partner institutions. How will AI assist medical professionals in diagnosis? Learn more: hkust.edu.hk/news/hkust-deve… #HKUST #HKUST35 #AIframework #MedicalImaging #MedicalModels

Specialists provide task-specific guidance, such as diagnostic predictions and visually similar clinical cases, helping MedDr reason across diverse medical scenarios instead of relying on a single model alone. 3/4

Introducing Qwen3! We release and open-weight Qwen3, our latest large language models, including 2 MoE models and 6 dense models, ranging from 0.6B to 235B. Our flagship model, Qwen3-235B-A22B, achieves competitive results in benchmark evaluations of coding, math, general capabilities, etc., when compared to other top-tier models such as DeepSeek-R1, o1, o3-mini, Grok-3, and Gemini-2.5-Pro. Additionally, the small MoE model, Qwen3-30B-A3B, outcompetes QwQ-32B with 10 times of activated parameters, and even a tiny model like Qwen3-4B can rival the performance of Qwen2.5-72B-Instruct. For more information, feel free to try them out in Qwen Chat Web (chat.qwen.ai) and APP and visit our GitHub, HF, ModelScope, etc. Blog: qwenlm.github.io/blog/qwen3/ GitHub: github.com/QwenLM/Qwen3 Hugging Face: huggingface.co/collections/Q… ModelScope: modelscope.cn/collections/Qw… The post-trained models, such as Qwen3-30B-A3B, along with their pre-trained counterparts (e.g., Qwen3-30B-A3B-Base), are now available on platforms like Hugging Face, ModelScope, and Kaggle. For deployment, we recommend using frameworks like SGLang and vLLM. For local usage, tools such as Ollama, LMStudio, MLX, llama.cpp, and KTransformers are highly recommended. These options ensure that users can easily integrate Qwen3 into their workflows, whether in research, development, or production environments. Hope you enjoy our new models!

deepseek在英文圈已经被吹上天了,发现中文圈还有很多非AI业内人士,对deepseek的能力没有一个清晰的认识,所以用中文发一条,先说结论,我认为行业贡献而言:GPT>deepseek>gemini>llama及其他 很多人的着眼点在于他用很少的卡也能训练出效果差不多的模型,但这是结果,更重要的他能做到这一点的技术: deepseek这次最亮眼的是证明了纯粹的outcome reward RL能够直接把模型提到o1水平,在他出来之前,业内所有人(包括deepmind)都认为需要prm (process reward model)才能做到这点,这就已经是颠覆行业的发现了,现在所有除gpt外的llm大组,都在推倒重来,copying他们的训练方法 另外非常重要的是deepseek还发现了这种训练方式甚至能够让模型自己学会longer-chain reasoning以及reflection,他们所谓“aha moment”。相当于只训练llm得到更准确的结果,llm就能自己学会反思,思考到一半知道自己这样做下去会错,然后尝试自己纠错,这种模型“自我进化”的特性是业内仅次于GPT intelligence emergence的重大发现 就结果而言,“用更少的卡训练出效果差不多的模型”可能不仅仅是节约成本这么简单,更是一种improvement of scaling law,意味着这种方法往上堆更多的卡有可能把模型能力再往上提升一个数量级,甚至直接达到AGI/ASI 这就是为什么这次业内这么hyper,deepseek开源的价值远大于llama,llama基本是大家已知的方法堆卡训练,deepseek带来太多的惊喜

Tencent presents GameGen-O Open-world Video Game Generation We introduce GameGen-O, the first diffusion transformer model tailored for the generation of open-world video games. This model facilitates high-quality, open-domain generation by simulating a wide array of game engine features, such as innovative characters, dynamic environments, complex actions, and diverse events. Additionally, it provides interactive controllability, thus allowing for the gameplay simulation. The development of GameGen-O involves a comprehensive data collection and processing effort from scratch. We collect and build the first Open-World Video Game Dataset (OGameData), amassed extensive data from over a hundred of next-generation open-world games, employing a proprietary data pipeline for efficient sorting, scoring, filtering, and decoupled captioning. This robust and extensive OGameData forms the foundation of our model's training process. GameGen-O undergoes a two-stage training process, consisting of foundation model pretraining and instruction tuning. In the first phase, the model is pre-trained on the OGameData via the text-to-video and video continuation, endowing GameGen-O with the capability for open-domain video game generation. In the second phase, the pre-trained model is frozen, and we fine-tuned using a trainable InstructNet, which enables the production of subsequent frames based on multimodal structural instructions. This whole training process imparts the model with the ability to generate and interactively control content. In summary, GameGen-O represents a notable initial step forward in the realm of open-world video game generation via generative models. It underscores the potential of generative models to serve as an alternative to rendering techniques, which can efficiently combine creative generation with interactive capabilities.

Extending an LLM for new knowledge sources is tedious—fine-tuning is expensive/causes forgetting, LoRA is restrictive. Excited to share our work where we show that an LLM can be efficiently *composed* with specialized (L)LMs to enable new tasks! arxiv.org/abs/2401.02412 🧵(1/8)
