One control plane for every model you call.
STACK Vault's STACK Mesh routes traffic across providers based on cost, latency, sensitivity, and risk — with full audit logs and instant provider failover.
Right model, right call, right cost
Hard-coded provider clients are a liability. Mesh policies stay in version control, not in client code.
Cost-Aware Routing
Cheapest provider that meets quality SLO for the request class. Live re-pricing as provider rates change.
Sensitivity Routing
Sensitive prompts pinned to on-prem or BAA-covered providers. Public prompts free to roam.
Provider Failover
Sub-second cutover when OpenAI, Anthropic, or Bedrock degrades. Your users never see a 5xx.
Quality A/B
Shadow-traffic new models against production with paired evals before you flip the switch.
Centralized Auth
One credential per tenant. We broker provider keys. Devs don't see them.
Per-Call Audit
Every request logged with prompt fingerprint, sensitivity class, provider, latency, and cost.
Questions teams ask before deploying
Straightforward answers about scope, integration, data handling, and rollout.
Is this an OpenAI-compatible gateway?
Yes. Drop-in /v1/chat/completions endpoint. Most apps need zero code change beyond the base URL.
Do you support our on-prem GPU cluster?
Yes. vLLM, TGI, TensorRT-LLM, and Triton endpoints register the same way commercial providers do.
How do you handle streaming?
Native SSE passthrough. Streaming routing decisions fire on first-token, not on completion.
Where does prompt data live?
In your VPC. We log metadata; raw prompt content stays in tenant storage you control.
