Token cues in training data drive base model reasoning, rivaling RL performance.

8/10

This paper demonstrates that specific starting tokens in base language models act as cues that trigger reasoning behaviors, achieving performance competitive with RL-trained models on math and coding tasks. The authors show that RL training primarily increases the likelihood of these cues rather than fundamentally altering reasoning capabilities. Through causal data interventions, they prove that arbitrary words can be converted into effective reasoning cues by modifying their association with training data. Additionally, the study links these token cues to specific document types in the training set and explores their impact on safety behaviors like refusal.

MemPilot uses RL to orchestrate on-demand multimodal memory curation for LLM agents.

6/10

MemPilot is a framework that optimizes a multi-step LLM policy via reinforcement learning to manage agent memory dynamically. It allows the system to choose between retrieving from static memory or delegating query-specific curation of raw multimodal history to heterogeneous LLMs and VLMs. The policy jointly controls evidence amount, curation instructions, model selection, and visual access to balance performance, cost, and latency. The authors introduce objective-wise advantage decoupling and prefix-based marginal utility estimation for fine-grained credit assignment. Experiments on five benchmarks show that MemPilot achieves favorable trade-offs across different optimization preferences compared to existing baselines.

CLIFT uses conformal self-verification to improve web agent training and test-time scaling without e

7/10

Researchers introduced CLIFT, a method for training and scaling web agents using conformal self-verification to address sparse reward signals and high judge costs. During training, a Compositional Conformal Certifier filters self-generated verification questions based on URL-conditional evidence to create reliable per-step rewards. At test time, the frozen certified bank enables Conformal Trajectory Selection, allowing agents to choose optimal rollouts via majority voting without external LLM judges. The approach achieves state-of-the-art results on WebArena Infinity and VisualWebArena, and improves zero-shot performance on Online Mind2Web by transferring the certified question bank to different models.

Paradee distills Kokoro-82M into an 8M-param TTS model running 25x real-time on CPU.

6/10

Researchers distilled the Kokoro-82M text-to-speech model into Paradee, an 8.07M-parameter single-voice variant. The model uses a two-stage training process with spectral and adversarial losses, requiring no alignment learning or joint training. Paradee achieves 10x fewer parameters and 15x less compute than the teacher model while maintaining high audio quality (UTMOS 4.41 vs 4.52). It runs 25x faster than real time on a single CPU thread and is stored in int8 format at 8.5 MB.
