Multimodal LLMs excel at holistic image captioning but struggle with pixel-level spatial grounding due to lack of spatial supervision. Xiaomi AI Lab unveiled Xiaomi-Lens-0 (arXiv:2610.23279), a 4B MLLM based on Qwen3.5 that natively predicts pixel masks. A lightweight decoder integrates patch embeddings, visual latents, and mask-token activations, driving RefCOCO comprehension (REC [email protected]: 94.6% / 92.1% / 92.5%) and segmentation (RES cIoU: 83.4% / 79.9% / 81.1%) past Florence-2 and LISA-7B while preserving a 69.7% MME-RW score.

While deep research (DR) agents excel on synthetic and academic queries, their reliability in realistic personal life and professional workflows remains uncharted. Tencent Hunyuan introduces LifeSearch, a rigorous benchmark featuring 203 real-user tasks across 7 domains backed by 4,500+ hours of expert annotation and 4,000+ fine-grained rubrics. Evaluating 12 leading DR agents reveals that the strongest frontier agent scores only 63.4%, unmasking persistent bottlenecks in multi-step information synthesis and constraint verification.

Recent attempts to scale tool-use post-training for autonomous agents have focused primarily on synthesizing standalone execution environments. However, environments constitute merely one component of a holistic agentic interaction system comprising environments, tasks, harnesses, and evaluators; scaling environments in isolation yields inconsistent training signals. Researchers from Fudan University introduce WEFT (arXiv:2609.36887), a whole-system evolution framework for tool-use post-training. WEFT coordinates environment breadth, task complexity, and interaction diversity, applying execution-driven self-evolution to attribute failures and iteratively revise flawed components. To ensure optimization stability and concurrency reliability, WEFT introduces prefix-preserving sampling, atomic-turn credit assignment, and MegaMCP—a Model Context Protocol infrastructure providing isolated, recoverable state management across concurrent rollouts. WEFT-8B and WEFT-14B outperform matched environment-scaling baselines across BFCL V4, tau^2-Bench, and Claw-Eval, with WEFT-14B beating Agent-World-14B by 6.41, 2.23, and 12.27 percentage points, while WEFT-35B-A3B excels on long-horizon benchmarks like Toolathlon-Verified.

While reinforcement learning produces distinct specialized expert models excels at mathematics, code synthesis, or instruction following, real-world deployment requires a single unified foundation model possessing all of these capabilities. Multi-teacher on-policy distillation (MOPD) aims to merge these capabilities by routing student-sampled prompts to domain specialists for token-level supervision. However, researchers discover an acute imbalance across Qwen3.5 architectures: instruction-following teachers exhibit broad distribution dispersion, generating gradient magnitudes that overwhelm dense mathematical signals and degrading mathematical reasoning. The team introduces Domain-Normalized MOPD (DN-MOPD, arXiv:2609.35347), which normalizes each domain's supervisory signal by its measured empirical spread. Across six public benchmarks, DN-MOPD consistently outperforms standard MOPD across all model scales, recovering mathematical reasoning performance without sacrificing instruction compliance.

While LLM agents excel in multi-step decision-making, they transfer poorly to unseen environments. Conventional world-model approaches predict future observations, incurring high training overhead and compounding planning errors. EVOKE demonstrates that digital world knowledge is already internalized during pretraining, and failure to transfer stems from single-goal post-training that encourages superficial contextual shortcuts. By holding environment states fixed while ranking candidate actions across diverse counterfactual goals, EVOKE compels policies to elicit internalized world dynamics, boosting generalization across unseen environments.

Researchers from New York University in collaboration with Google DeepMind's Rémi Munos have published 'Learning to Discover Interesting Mathematics' (arXiv: 2609.28603). While LLMs excel at proving existing conjectures, autonomous mathematical expansion has been crippled by models spamming trivial or useless lemmas. The authors formulate a metric for intrinsic mathematical interestingness—defined by the compression ratio between proof length and statement brevity. Powered by a specialized 27B proof-difficulty model, the framework autonomously conjectures, verifies, and curates high-value theorems, enabling self-expanding formal mathematical libraries without human-specified goals.
