With the largest video segmentation dataset to date, SAM 2 achieves superior accuracy with fewer user interactions. It’s six times faster and more accurate than its predecessor, SAM. The model, along with its dataset and an interactive demo, is publicly available for exploration and use.
3. MindSearch: Enhancing Web Search with Cognitive AI
MindSearch is an innovative AI framework designed to mimic human cognitive processes for improved web information retrieval and integration. By using a multi-agent system, MindSearch can break down complex queries, search across multiple web pages, and compile relevant information efficiently. This approach significantly enhances the quality and speed of responses, outperforming current AI search engines like ChatGPT-Web and Perplexity.ai.
4. Theia: Integrating Vision Models for Superior Robot Learning
Theia is a vision foundation model specifically designed for robots, integrating multiple existing vision models to boost robot learning capabilities. It encodes diverse visual knowledge, allowing robots to learn more effectively with less training data. In experiments, Theia outperformed previous models and even its own training models, demonstrating superior efficiency and effectiveness in vision-based robot policy learning.
5. MoMa: Efficient Mixed-Modal Pre-training with Specialized Experts
MoMa is a new architecture tailored for pre-training mixed-modal language models, capable of efficiently handling both images and text. It employs modality-specific expert modules, which significantly improve pre-training efficiency. With a 1-trillion-token budget, MoMa achieves a 3.7x overall savings in FLOPs, outperforming traditional models. When combined with a mixture-of-depths approach, it further increases efficiency, though this can impact causal inference performance.
