📄 Top Research Papers
Architectures for Building Agentic AI |
A comprehensive paper arguing that reliability of agentic AI is primarily an architectural property. Proposes a practical taxonomy including tool-using agents, memory-augmented agents, planning agents, and multi-agent systems with design guidance for production deployment. Possible Impact: Essential reading for developers building production AI agents. |
Mull-Tokens: Modality-Agnostic Latent Thinking |
Introduces a novel approach to multimodal reasoning using modality-agnostic latent tokens that enable models to "think free-form" across text and images, achieving up to +16% improvement on puzzle-solving tasks. Possible Impact: Advances multimodal AI reasoning capabilities significantly. |
Stronger Normalization-Free Transformers |
Introduces Derf, a new function design that outperforms LayerNorm and RMSNorm across vision, speech, and DNA modeling—demonstrating practical alternatives to normalization layers. Possible Impact: Could improve transformer efficiency across multiple domains. |
