OpenAI-Compatible Layer

An API pattern in which other model providers imitate the OpenAI interface specification, such as the /v1/chat/completions endpoint and identical request and response structures. This allows developers to call models from different vendors using the same client code, reducing integration effort and simplifying migration between providers. The compatibility layer typically maps vendor-specific parameters onto OpenAI-style fields and normalizes error formats so that existing SDKs and tooling continue to function without modification.
