156		−	these calls answer with a message saying so.
	155	+	Each workspace decides how its agents reach a model: its own provider
	156	+	(connected under Integrations, billed by the provider) works for any
	157	+	workspace; g1t's hosted models are open to selected workspaces until
	158	+	payments go live. Without either, these calls answer with a message saying

	206	+	kind of work routed to one of them or to g1t's hosted models
