B.AI has resumed its Claude Fable 5 API service following Anthropic's global security strategy adjustments and redeployment. The AI infrastructure platform has fully integrated the service, ensuring stable operation of underlying models. The restoration includes a dual-channel model offering both "Official" and "Self-selected Service Providers," designed to meet diverse computing power and cost needs for developers and enterprises. The service is now live on the B.AI website for user access.
