Evaluation Replaces Training As The Central Workflow
An organisation that trains a model measures it against a validation set and moves on. An organisation calling somebody else's model has no such artefact and must build its own evidence that the system does what the task requires, which means task-specific test sets, human review workflows, regression suites and runtime guardrails. That work did not exist as a tooling category five years ago and is now the fastest growing part of this market at 26.7% against 17.8% overall. Provider models change under customers without warning, which makes continuous evaluation permanent rather than a launch activity.
