Today, we introduce VantAI's first foundational model: Neo-1. Neo-1 unifies structure prediction and molecular design at an atomic level, allowing prompting with multimodal and fine-grained structural information both for individual molecules and their interactions. In addition to designing biomolecules, this programmability allows Neo-1 to accelerate the collection of structural data when combined with our cross-linking mass spectrometry (XLMS) platform, NeoLink https://www.vant.ai
