LLaDA-Image: Building Strong Image Generators with Fully Open Training Recipes
HF ★ 56 · Chuyan Chen, Haoxing Chen, Kun Chen… · HF Mirror
This release introduces the LLaDA-Image image generation framework, equipped with a 6B parameter diffusion Transformer trained from scratch and a frozen LLaDA2.0-Mini vision-language module. It first constructs generation priors via pure image pretraining, and uses parameter-free RMSNorm and Muon optimizer to improve efficiency. The model generates highly realistic outputs, responds to fine-grained editing instructions, and has a distilled Turbo version supporting 2-4 step fast inference. It achieves open-source SOTA on both Chinese and English tracks of Qwen-Image-Bench, with all related weights, code, and training plans fully open-sourced.
LatentPress: Context Compression Beyond Text and Vision
HF ★ 48 · Zhengze Zhou, Hejian Sang · HF Mirror
To address the issue that existing LLM context compression relies on human-readable text and images, requiring inefficient decoding, this study proposes the LatentPress solution: only train an adapter layer with 0.1% of the decoder’s parameter count to convert long text and conversation history into continuous memory tokens, which the frozen decoder can read directly without text reconstruction. This solution achieves a compression ratio of 4-16x, outperforms uncompressed context in accuracy at 7.7x compression, is an order of magnitude faster than solutions like text summarization, has cross-domain transferability, and can serve as a machine-specific context representation interface.
Why Gated DeltaNet Survives 4-Bit Quantization: NVFP4 W4A4 for the Recurrent Half of a Hybrid 27B LLM
HF ★ 47 · Sergii Kozyrev, Davyd Maiboroda · HF Mirror
Addressing the previous misconception that Gated DeltaNet (GDN) in hybrid 27B LLMs is not suitable for 4-bit quantization, this study uses NVFP4 format to perform W4A4 full quantization on all linear layers of Qwen3.8-27B (including GDN), and fixes the scale matching issue in kernel fusion. The resulting model has performance close to BF16 precision, only takes up 17.5GiB of space, and has a 14-19% faster prefill speed. The study also reveals the internal mechanism of GDN’s quantization tolerance, and provides a implementation plan for full quantization of hybrid LLMs.
Random Attention: Rethinking KV Cache Eviction for Efficient Reasoning
HF ★ 37 · Heng Wang, Jielin Qiu, Wenting Zhao… · HF Mirror
To solve the KV cache memory bottleneck in long inference scenarios for LLMs, where existing compression solutions all adopt the paradigm of scoring and filtering high-value tokens, this paper proposes a scoring-free random attention strategy: keep prompts, and randomly evict other tokens within each attention head. This method matches the performance of current state-of-the-art eviction strategies, and delivers 32%~43% higher throughput when deployed with vLLM. Its effectiveness comes from the fact that prompts are the core of the cache, and there are two layers of redundancy in inference trajectories: text-level and cross-head, so random selection can already retain enough necessary information.
RealSWE: A Compositional Evaluation of Coding Agents under Realistic User Requests
HF ★ 6 · Gyuhyeong Kim, Hyojung Gwon, Jeonghyeon Kim… · HF Mirror
Addressing the gap between common SWE evaluation benchmarks for coding agents and short, unstructured coding requests from real users, this study builds the RealSWE evaluation dataset covering different information compositions and language styles. Tests find that real-style inputs reduce the coding problem solving rate of LLMs by an average of 6.4 percentage points, and even change model rankings; only explicitly stating expected behavior and motivation can significantly improve efficiency, while other supplementary information and language styles have minimal impact.

WMLLM: Self-Evolving Optimization Agents via Predict-Then-Act World Modeling
Zhongzheng Li, Qingsong Ran, Shikun Feng…
Addressing the pain points of high-dimensional weakly structured search spaces in black-box optimization and low sample efficiency of existing methods, this paper proposes the WMLLM self-evolving optimization agent framework: it builds a “predict-then-act” world model based on the implicit knowledge of LLMs, first predicts feasible optimization directions before generating candidate solutions, and combines multi-round iteration, population search, and reinforcement learning to iteratively update its own model and strategy synchronously. It delivers better performance on tasks such as multi-objective molecular optimization, and achieves state-of-the-art performance under limited evaluation budgets.
DiDrive: A Risk-Aware Hierarchical Diffusion Framework for Safe Offline Reinforcement Learning in Autonomous Driving
Qisong Guo, Jingtang Chen, Zhilin Chen…
Addressing security pain points such as distribution shift, outlier action generation, and high-dimensional state redundancy when combining diffusion models with offline reinforcement learning in the autonomous driving field, this paper proposes the DiDrive risk-aware hierarchical diffusion framework: it filters environmental redundancy and focuses on security threats through the risk-aware hierarchical diffusion module, paired with the 3DICE optimization paradigm to alleviate outlier overestimation and gradient oscillation. CARLA benchmark tests show that its performance outperforms mainstream baselines such as IQL, with a success rate of 85% in high-density traffic scenarios with 60 vehicles, providing a robust path for safe autonomous driving decision-making.
Prompt-Space Meta-Learning Does Not Transfer Across Users: A Frozen-LLM Negative Result
Liam Byrne, David Dylan, Orla Fitzgerald…
This study verifies the cross-user transferability of prompt-space meta-learning in personalized scenarios with frozen LLMs. It designs the Muse framework to evolve shared adaptive prompts across users, paired with multiple control groups for testing on two LaMP personalized benchmarks. The results show that this type of meta-learning brings no significant gain, and even performs worse than ordinary few-shot retrieval, mainly due to meta-objective collapse: it only learns instruction polishing and validation overfitting, and cannot generate transferable adaptation strategies. The study also proposes a control protocol that eliminates confounding factors.

Harness Engineering for Self-Improvement
Lilian Weng
Recursive Self-Improvement (RSI) can be traced back to the concept of superintelligent machines proposed by I.J. Good in 1965: such systems have intelligence far exceeding that of humans, and can independently design better machines to achieve self-iteration. In 2008, Eliezer Yudkowsky clarified that its core is the feedback loop where AI uses its existing intelligence to optimize its own cognitive mechanism. Currently, such AI feedback loops can be manifested as the model directly rewriting its own weights, or optimizing its own training process.
