LLM MigrationAI InfrastructureProvider MigrationLLM API
Switching LLM providers can reduce cost or improve quality, but migration should be tested carefully.
Checklist
Verify:
- SDK compatibility
- model names
- prompt behavior
- streaming
- structured output
- tool calling
- error handling
- latency
- token accounting
- cost per task
- fallback rules
- logging
Roll out gradually
Start with internal users, then a small percentage of traffic, then broader rollout. Keep rollback easy.
Compare outputs
Run both providers on the same evaluation set before switching production traffic.
Final thoughts
LLM migration is safest when measured, gradual, and reversible. Use evaluations and logs to guide decisions.
