Plugsky is an AI infrastructure platform that gives developers and businesses access to models, agents, RAG, tools, and deployment options through a single API. Its OpenAI-compatible interface allows teams to migrate existing applications by changing the base URL while continuing to use familiar SDKs and workflows. The platform supports more than 31 first-party and partner models, including chat, reasoning, coding, vision, and embedding models. Plugsky offers flat-rate pricing with unlimited usage under fair-use limits, helping teams avoid unpredictable per-token costs and rate-limit surprises. Businesses can deploy on Plugsky’s cloud, their own cloud, private regional infrastructure, or on-premises environments depending on compliance and data residency requirements. Agent Cloud enables teams to build AI agents with function calling, memory, orchestration, tools, and private knowledge retrieval. Plugsky also includes Model Fusion, a marketplace for agents and prompt packs, white-label model options, and integrations for developers and SaaS teams. Enterprise controls such as SSO, RBAC, audit logs, SLAs, GDPR alignment, PDPL support, and private endpoints make it suitable for regulated industries. Plugsky gives organizations a flexible way to build, scale, and control AI applications without being locked into a single model provider or deployment environment.
