A new arXiv preprint introduces 3D-Fit, a token-efficient benchmarking strategy for evaluating general-purpose LLMs on structure-based drug design (SBDD) tasks requiring 3D spatial reasoning. The study compares LLMs against specialized diffusion model baselines on pocket-conditioned ligand generation with constraints including anchor fragments, pharmacophore points, and mandatory pocket-ligand interactions. Results show LLMs still lag behind state-of-the-art diffusion models but demonstrate promising ability to handle multiple simultaneous spatial constraints, suggesting a viable path for LLM-based molecular design.
