The SAMPL8 host-guest challenge provided a platform to test the reliability and accuracy of current computational methods and tools to predict absolute binding free energies. As part of this challenge, hosts CB8 and TEMOA were revisited with new guest libraries, including a new host in the Gibb deep cavity cavitand family (of which the "octa-acid" host, common to several previous SAMPLs, is a member), TEEOTA.
