This confluence of technological progress is transforming AI from monolithic cloud systems into versatile, edge-enabled tools that permeate everyday life, industry, and society at large.
Hardware-Software Co-Design and Next-Generation Chips: Pushing the Limits of Throughput and Efficiency
A central theme of 2026 has been the rapid advancement of hardware specifically optimized for large language models (LLMs) and multimodal AI systems. The advent of high-throughput LLM chips, exemplified by efforts like Reiner Pope’s development of LLM chips delivering substantially higher throughput than existing solutions, underscores the industry’s focus on co-designing hardware and software. These chips, such as the N5 series, leverage custom accelerators and parallel processing architectures to maximize efficiency, enabling real-time reasoning on resource-constrained devices.
The N5 chips reinforce a broader trend of hardware-software co-design, which ensures that computing architectures are tightly integrated with the demands of modern models. This synergy has led to dramatic reductions in latency and energy consumption, making it feasible to deploy large models like Llama 3.1 70B on low-power devices through sub-1-bit quantization techniques. The result is cost-effective, scalable AI that can operate locally without relying on cloud infrastructure, thus expanding AI’s reach into autonomous vehicles, robotics, IoT, and edge computing.

veScale-FSDP: The introduction of veScale-FSDP (Flexible and High-Performance Fully Sharded Data Parallel) has revolutionized the way large models are trained. By offering scalable, memory-efficient distributed training, veScale-FSDP allows researchers to train models beyond the 50-billion-parameter mark with significantly reduced hardware costs and energy consumption.
-
Scaling Fine-Grained Mixture of Experts (MoE): Researchers like Jakub Krajewski have pushed the boundaries of MoE architectures, scaling fine-grained MoE models beyond 50B parameters. These models intelligently activate only relevant parts of the network during inference, leading to massive parameter counts without a proportional increase in computational load, thus enhancing efficiency.
-
New Methods for Training Efficiency: A recent breakthrough involves novel methods to increase LLM training efficiency. Techniques such as optimized gradient accumulation, adaptive sparsity, and dynamic routing have contributed to reducing training time and resource requirements while maintaining or improving model performance.
Architectural Innovations and Diffusion Techniques: Improving Reasoning and Generation
2026 also heralds a new era of hybrid and diffusion-based architectures designed to enhance reasoning, sampling speed, and interpretability:
-
Mercury 2: The Reasoning Diffusion LM: This milestone model combines diffusion priors with refined Variational Autoencoders (VAEs) to process over 1,000 tokens per second—a groundbreaking feat. Unlike traditional autoregressive models, Mercury 2 employs diffusion-based sampling to accelerate multi-hop reasoning and complex inference, maintaining high fidelity and robustness.
-
Hybrid Generative Models: The resurgence of VAE and diffusion prior hybrids supports controllable, diverse, and reliable multimodal generation. These models underpin systems capable of reasoning across vision, language, and audio modalities, facilitating more human-like perception and multi-sensory grounding.
-
Tri-Modal Masked Diffusion: Innovations like The Design Space of Tri-Modal Masked Diffusion Models enable simultaneous processing of visual, textual, and auditory inputs. These architectures employ masked diffusion techniques to learn inter-modal correlations, yielding more accurate grounding and context-aware reasoning essential for embodied AI and robotics.
