[Blackbox](https://citeware.io/products/blackbox): Encrypted single-tenant inference plus a 300+ model router behind one endpoint Pricing: Starts at Custom (annual per-token commit; no published entry price). Blackbox routes 300+ open and closed models through one OpenAI-compatible endpoint and runs open-weight models as single-tenant deployments on Blackbox GPUs. Enterprise engineering and security teams buy Blackbox for gateway-enforced zero data retention, end-to-end encryption, and one annual per-token commit that covers every surface. Best for: Teams serving open-weight frontier models such as Nemotron Ultra on isolated capacity for regulated workloads and consolidating scattered OpenAI, Anthropic, and Google spend behind one endpoint and one invoice Features: Blackbox Router exposes 300+ hosted open and closed models through one OpenAI-compatible endpoint with one key, one bill, and one dashboard, Blackbox Enterprise Inference runs the open-weight model you choose on reserved, single-tenant GPU capacity, End-to-end encryption on every connection plus encryption at rest, Zero data retention enforced at the gateway, contractual under the Enterprise DPA, PII removed before prompts reach closed models on Enterprise, Smart routing, failover, and prompt caching included at no extra platform fee 4. [Seldon](https://citeware.io/products/seldon): Kubernetes-native MLOps and LLMOps serving, from open-source inference to enterprise governance Pricing: Starts at $0/month. Seldon turns trained models into Kubernetes resources, wiring Kafka-powered inference pipelines, drift detection, explainability and audit logging into one stack that platform engineers at banks, pharma firms and telecoms run on any cloud or on-premise. Seldon's multi-model serving with LRU memory overcommit hosts more models than GPU Best for: AI platform engineering leads in regulated enterprises who must serve, monitor and explain production models inside their own Kubernetes clusters instead of a vendor's hosted endpoint. Features: Seldon Core 2 declares models and pipelines as Kubernetes custom resources, Automatic inference server selection, scaling, monitoring and audit logging from one manifest, Composable data-centric pipelines connecting models, processing steps, custom logic and monitors over Kafka, MLServer lightweight multi-framework inference server with REST and gRPC support, Open Inference Protocol compatibility across model types, A/B tests, canary deployments, shadow deployments and multi-armed bandits for production routing 5.
