PLAID: Multimodal Protein Generation Model
Read Full Article: PLAID: Multimodal Protein Generation Model
PLAID is a groundbreaking multimodal generative model that addresses the challenge of simultaneously generating protein sequences and 3D structures by leveraging the latent space of protein folding models. Unlike previous models, PLAID can generate both discrete sequences and continuous all-atom structural coordinates, making it more practical for real-world applications such as drug design. This model can interpret compositional function and organism prompts, and is trained on extensive sequence databases, which are significantly larger than structural databases, allowing for a more comprehensive understanding of protein generation. The PLAID model utilizes a diffusion model over the latent space of protein folding models, specifically using ESMFold, a successor to AlphaFold2. This approach allows for the training of generative models using only sequence data, which is more readily available and less costly than structural data. By learning from this expansive data set, PLAID can decode both sequence and structure from sampled embeddings, effectively using the structural information contained in pretrained protein folding models for protein design tasks. This method is akin to vision-language-action models in robotics, which use vision-language models trained on large-scale data to inform perception and reasoning. To address the challenges of large and complex latent spaces in transformer-based models, PLAID introduces CHEAP (Compressed Hourglass Embedding Adaptations of Proteins), which compresses the joint embedding of protein sequence and structure. This compression is crucial for managing the high-resolution image synthesis-like mapping required for effective protein generation. The approach not only enhances the capability to generate all-atom protein structures but also holds potential for adaptation to other multimodal generation tasks. As the field advances, models like PLAID could be pivotal in tackling more complex systems, such as those involving nucleic acids and molecular ligands, thus broadening the scope of protein design and related applications. Why this matters: PLAID represents a significant step forward in the field of protein generation, offering a more practical and comprehensive approach that could revolutionize drug design and other applications by enabling the generation of useful proteins with specific functions and organism compatibility.

Adapting Agentic AI: New Framework from Stanford & Harvard
Read Full Article: Adapting Agentic AI: New Framework from Stanford & Harvard
Agentic AI systems, which build upon large language models by integrating tools, memory, and external environments, are currently used in various fields such as scientific discovery and software development. However, they face challenges like unreliable tool use and poor long-term planning. Research from Stanford, Harvard, and other institutions proposes a unified framework for adapting these systems, focusing on a foundation model agent with components for planning, tool use, and memory. This model adapts through techniques like supervised fine-tuning and reinforcement learning, aiming to enhance the AI's ability to plan and utilize tools effectively. The framework defines four adaptation paradigms based on two dimensions: whether adaptation targets the agent or tools, and whether the supervision signal comes from tool execution or final agent outputs. A1 and A2 paradigms focus on agent adaptation, with A1 using feedback from tool execution and A2 relying on final output signals. T1 and T2 paradigms concentrate on tool adaptation, with T1 optimizing tools independently of the agent and T2 adapting tools under a fixed agent. This structured approach helps in understanding and improving the interaction between agents and tools, ensuring more reliable AI performance. Key takeaways include the importance of combining different adaptation methods for robust and scalable AI systems. A1 methods like Toolformer and DeepRetrieval adapt agents using verifiable tool feedback, while A2 methods optimize agents based on final output accuracy. T1 and T2 paradigms focus on training tools and memory, with T1 developing broadly useful retrievers and T2 adapting tools under a fixed agent. The research suggests that practical systems will benefit from rare agent updates combined with frequent tool adaptations, enhancing both robustness and scalability. This matters because improving the reliability and adaptability of agentic AI systems can significantly enhance their real-world applications and effectiveness.
