Company Overview
Guide Labs is a product-focused artificial intelligence research company developing a new class of interpretable foundation models that are designed to be understood, debugged, and steered by human experts. The company's core mission is to move beyond opaque, "black-box" AI systems by engineering models that can reliably explain their reasoning and outputs. These models allow users to understand which parts of a prompt were important, identify the training data that influenced a result, and verify the model's decision-making process. This approach is aimed at increasing the safety, reliability, and trustworthiness of AI in critical domains such as medicine, finance, and drug discovery. Guide Labs, which participated in Y Combinator's Winter 2024 batch, makes its models available to partners and customers via an API.
