This academic paper introduces ToonComposer, a novel generative AI model designed to streamline cartoon and anime production by unifying the typically separate and labor-intensive stages of inbetweening and colorization into a single "post-keyframing" process. The model leverages a Diffusion Transformer (DiT) architecture, adapted for cartoon aesthetics using a Spatial Low-Rank Adapter (SLRA) to maintain temporal coherence. ToonComposer features a sparse sketch injection mechanism for precise artist control, even with minimal inputs, and region-wise control to automatically generate content in unsketched areas. Extensive evaluations on both synthetic and human-drawn benchmarks, including a new PKBench dataset, demonstrate ToonComposer's superior visual quality, motion consistency, and production efficiency compared to existing methods. The paper highlights its potential to significantly reduce manual workload and enhance flexibility in animation workflows.

This document introduces Dynamic Fine-Tuning (DFT), a novel method designed to enhance the generalization capabilities of Large Language Models (LLMs) during Supervised Fine-Tuning (SFT). The authors present a mathematical analysis that reveals how standard SFT gradients implicitly contain a problematic reward structure akin to reinforcement learning (RL), which limits its effectiveness. DFT addresses this by dynamically re-weighting the objective function with the probability of each token, a simple single-line code change. Extensive experiments on mathematical reasoning benchmarks demonstrate that DFT significantly outperforms traditional SFT and even competes favorably with more complex RL methods in offline settings, offering a more robust and efficient fine-tuning alternative.
The source critically examines recent research suggesting that AI systems might be developing a capacity for "scheming," defined as covertly and strategically pursuing misaligned goals. It draws a parallel between current AI "scheming" research and past attempts to teach apes human language, highlighting similar methodological pitfalls. The paper argues that both fields suffered from overattribution of human traits, excessive reliance on anecdote, and a lack of strong theoretical frameworks. It systematically critiques the current methods used to assess AI scheming, pointing out deficiencies such as anecdotal evidence, absence of control conditions, weak theoretical motivation, and exaggerated interpretations. Ultimately, the source advocates for more rigorous scientific practices, including quantitative analysis, clear hypothesis testing, and cautious use of mentalistic language, to ensure claims about AI scheming are defensible and to foster a more productive research program.
This document comprehensively reviews various reinforcement learning (RL) techniques used to improve the reasoning abilities of large language models (LLMs). The authors address the lack of standardized guidelines and conflicting research findings in this rapidly developing field by performing rigorous, isolated evaluations of common RL techniques. Through these experiments, they analyze the internal mechanisms and applicable scenarios for methods like normalization, clipping, filtering, and loss aggregation. The paper culminates in the proposal of "Lite PPO," a minimalist combination of two techniques that demonstrates superior performance over more complex algorithms by leveraging robust advantage normalization and token-level loss aggregation for non-aligned models. Ultimately, the work aims to provide clear, empirically-backed guidelines for practitioners and advance the understanding of RL for LLMs.
