Open agent frameworks and hosted assistants: when to use them
LangChain, CrewAI, AutoGen, n8n, and hosted assistant APIs - when they speed you up and when they add glue risk.

Direct answer
Use frameworks and hosted assistants when they shorten integration time without hiding ownership. Avoid them when they force multi-agent complexity you cannot eval or debug.
Hosted assistants
Fast tools + threads. Still need your gates, IAM, and business evals.
LangChain-class frameworks
Useful connectors and patterns; can become abstraction mazes.
Multi-agent frameworks
Only with clear role contracts and traces.
n8n/Zapier
See automation comparison post - great glue, limited NLP judgment.
Decision
Choose the thinnest layer that passes evals and your team can maintain.
