Latest 100 papers on foundation models: Feb. 21, 2026

Foundation models are revolutionizing AI, extending their reach beyond large language models to nearly every domain imaginable. From predicting Martian weather patterns to enhancing medical diagnostics and powering advanced robotics, these models are proving their versatility and capacity for complex reasoning. This digest dives into recent breakthroughs, highlighting how diverse research is pushing the boundaries of what these powerful, pre-trained systems can achieve.

The Big Idea(s) & Core Innovations

The recurring theme across recent research is the drive toward efficiency, interpretability, and real-world applicability for foundation models. Researchers are finding creative ways to adapt these massive models for specialized tasks, often with significantly less data or computational overhead than previously thought necessary.

In the realm of biological sciences, the paper, JEPA-DNA: Grounding Genomic Foundation Models through Joint-Embedding Predictive Architectures by authors from NVIDIA and the Icahn School of Medicine at Mount Sinai, introduces a pre-training framework that shifts from token-level reconstruction to latent feature prediction. This allows genomic foundation models to capture higher-order functional semantics, enhancing biological reasoning. Complementing this, research from Boston University in their paper, Parameter-free representations outperform single-cell foundation models on downstream benchmarks, remarkably demonstrates that simple, parameter-free linear methods can outperform complex single-cell foundation models in tasks like cross-species annotation, suggesting that much of the biological structure is captured through basic normalization. Furthermore, to address the challenge of limited data in single-cell transcriptomics, the paper, Scaling Laws for Masked-Reconstruction Transformers on Single-Cell Transcriptomics by Ihor Kendiukhov from the University of Tübingen, reveals that power-law scaling for masked-reconstruction transformers only emerges when sufficient data are available relative to model size, highlighting data scarcity as a key bottleneck.

Robotics and embodied AI are also seeing significant advancements. FRAPPE: Infusing World Modeling into Generalist Policies via Multiple Future Representation Alignment, from Han Zhao and Jbo Wang at Westlake University, enhances generalist robotic policies by aligning model features with multiple visual latent representations. This allows for more efficient learning from human video demonstrations without requiring action annotations. Similarly, RoboGene: Boosting VLA Pre-training via Diversity-Driven Agentic Framework for Real-World Task Generation introduces an agentic framework to automate the generation of diverse, physically plausible manipulation tasks, crucial for scalable VLA model pre-training. And RynnBrain: Open Embodied Foundation Models by authors from Alibaba Group, DAMO Academy, combines vision-language understanding with physical grounding, enabling robots to perform complex real-world tasks through spatio-temporal reasoning and physics-aware planning. For practical deployments, AsyncVLA: An Asynchronous VLA for Fast and Robust Navigation on the Edge optimizes Vision-Language-Action (VLA) models for edge devices, ensuring fast and robust navigation through asynchronous processing.

In medical AI, several papers highlight advancements in diagnostics and data generation. MedProbCLIP: Probabilistic Adaptation of Vision-Language Foundation Model for Reliable Radiograph-Report Retrieval from Texas A&M University-San Antonio and Boise State University, proposes a probabilistic framework for medical image-text retrieval, capturing uncertainty and improving reliability. MedVAR: Towards Scalable and Efficient Medical Image Generation via Next-scale Autoregressive Prediction introduces an autoregressive framework for high-resolution medical image synthesis, coupled with a harmonized multi-organ dataset for scalable generative modeling. A particularly groundbreaking work, Free Lunch in Medical Image Foundation Model Pre-training via Randomized Synthesis and Disentanglement by authors from the Hong Kong University of Science and Technology, demonstrates that synthetic data can effectively replace real medical datasets for pre-training robust and transferable medical image foundation models (MIFMs), addressing privacy concerns and data scarcity. Furthermore, Training-Free Zero-Shot Anomaly Detection in 3D Brain MRI with 2D Foundation Models extends zero-shot anomaly detection to 3D brain MRI using 2D foundation models and multi-axis tokenization, significantly reducing computational complexity.

Another innovative trend is the integration of diverse data modalities and problem-solving paradigms. AudioChat: Unified Audio Storytelling, Editing, and Understanding with Transfusion Forcing from Adobe Research, Carnegie Mellon University, and OpenAI, leverages LLM-based toolcalling agents and a novel training objective for generating, editing, and understanding complex multi-source audio scenes. Similarly, EIDOS: Latent-Space Predictive Learning for Time Series Foundation Models shifts time series pretraining from predicting observations to learning latent-space predictive dynamics, improving robustness and interpretability. For environmental monitoring, Detecting Brick Kiln Infrastructure at Scale: Graph, Foundation, and Remote Sensing Models for Satellite Imagery Data by a team including researchers from the University of Oxford, combines graph-based, foundation, and classical remote sensing models for scalable brick kiln detection, demonstrating the power of multimodal integration.
