In the post-GPT era, Llama-Gram represents a promising advancement in AI-driven chemical drug discovery, grounded in the chemical principle that molecular structure determines properties. This folding-based end-to-end framework seeks to address the hallucination issues of traditional large language models by integrating protein folding embeddings, graph-based molecular representations, and uncertainty estimation to better capture the structural complexities of protein-ligand interactions. By leveraging the frozen-gradient ESMFold model and a Graph Transformer variant, Llama-Gram aims to enhance predictive accuracy and reliability through grouped-query attention and a Gram layer inspired by support points theory. By incorporating protein folding information, the model demonstrates competitive performance against state-of-the-art approaches such as Transformer CPI 2.0 and Graph-DTA, offering improvements in compound-target interaction. Llama-Gram provides a scalable and innovative chemical theory that could contribute to accelerating the chemical drug discovery process.
