Vendor Lock-in

Definition

Vendor lock-in refers to a situation where a customer becomes dependent on a particular vendor for products and services, making it difficult to switch to another provider. Hardcoded AI model IDs in production code create operational lock-in to specific model snapshots.

API Model Lock-in (June 2026)

anthropic’s June 15, 2026 retirement of claude-sonnet-4-20250514 and claude-opus-4-20250514 demonstrates model lifecycle risk — applications with hardcoded IDs fail immediately with no grace period. Mitigation: abstract model strings behind configuration, monitor deprecation schedules (model-deprecation).
