The OpenAI first party provider (openai) for GPT series models is temporarily unavailable. Impact Requests that explicitly specify the openai first party provider—such as appending the :openai suffix to a model slug (for example, openai/gpt 6.1 sol:openai) or restricting provider.routing.providers to ["openai"]—will fail during this period. Requests using standard GPT model slugs without locking the openai provider continue to be routed automatically to available providers. Action Required If your requests specify the openai provider, please remove the :openai suffix (or remove the openai only provider routing restriction) so that ZenMux can automatically route your traffic to Azure (azure) and other available providers: Change openai/
