Same Model, Different Harness: CUGA, Hermes, and Deep Agents β When to Pick CUGA?
CUGA is IBM's open-source agent harness for enterprise work. IBM Research compared it with Hermes and Deep Agents on 90 AppWorld tasks, using GLM-5.3-flash for all three, and task completion ranged from 30% to 81% by harness. CUGA passed 20 of 30 scenarios on the consistency metric (SGC), Hermes 8 and Deep Agents 2. The post also describes CUGA's policy layer, which enforces approvals and tool guards in the runtime, and notes the CUGA team ran the test.
