MAIster has two distinct comparison surfaces. Flow Studio answers what changed in a process definition. Evaluation Lab answers which execution produced the better result.

​
Change a process

Use Flow Studio and package forks to edit a graph, fork installed package content, inspect upstream divergence, and apply a bounded AI-assisted change. Read the node catalog and structured-result contract before connecting data-dependent steps.

​
Compare implementations

Use Evaluation Lab for several Runs of one task. It can observe existing Runs or launch controlled variants across Flow revisions, agents, models, and capabilities. Objective checks and blinded AI judges contribute evidence; a person records the conclusive verdict. An evaluation never approves, promotes, or merges a participant automatically.
