The migration plan
Roughly 12 weeks for a mid-size estate, in six phases.
Tooling & automation
Deploy the open model on self-managed inference (vLLM/TGI) behind an OpenAI-compatible gateway, migrate prompts and evaluation suites, A/B test for quality, and shift traffic by workload.
OffVendor's wizard pre-fills these scripts with your environment — inventory export, disk/schema conversion, bulk provisioning, and validation.
Frequently asked
Is migrating from Cohere to OpenAI GPT worth it?
