ASO design
Benchmark-evaluated agents are capable of identifying FDA-approved drug candidates (nucleic acid sequences, proteins, or small molecules) as well as discovering novel drugs, further extending their potential for real-world drug discovery.
Data Curation
A MetaAgent achieves infinite memory by batch-processing unlimited items and synthesizing their summaries, maintaining awareness of all content without context constraints
AI-driven drug discovery (AIDD) integrates advanced machine learning and computational modeling to streamline therapeutic development
AIDD leverages deep learning and generative models to transform the drug discovery pipeline—including target identification, molecular design, and preclinical evaluation, uncovering novel therapeutics with greater speed, precision, and scalability.
At KumiChem™, we deliver a human-centered platform that amplifies the AIDD process through high-level automation and the seamless integration of expert knowledge with AI-driven innovation.
