Reality check

The useful boundary is what works repeatedly in a real environment—not what looks impressive in a demo.

Works well when

Knowledge lookup, drafting and multi-step workflows with review
Tasks with clear tools, permissions and success criteria
Teams that can evaluate outputs with real examples

Verify before buying

Prompt/version history, traces, evaluations and cost
Data retention, model providers and tool permissions
Human approval for irreversible or sensitive actions

Not a magic solution

An unsupervised decision-maker for high-stakes work
A replacement for an unclear business process
A guarantee that a larger model removes all errors
