AI Vendor Lock-In

Simple Definition

AI vendor lock-in happens when your prompts, workflows, data, agents, or automations become so tied to one AI provider that switching becomes difficult.

If everything you build only works inside one AI platform, leaving that platform becomes painful, slow, or expensive.

How Lock-In Happens

Lock-in builds up quietly — through prompts tuned to one model, automations wired to one API, memory and files stored in one tool, or team habits formed around one assistant. The deeper the integration, the harder it is to leave.

Example

A business builds all of its internal automations around one provider’s AI agents, custom instructions, memory, and API. Moving to another provider would mean rebuilding much of it from scratch.
