Multi-provider AI infrastructure
An AI gateway built for decisions—not just requests.
Layer8 Adaptive gives platform teams one governed execution envelope for model access, policy, routing, validation, repair, approvals, usage, and provenance. It handles the ordinary gateway work while adding controls for agentic workflows that cannot be treated like stateless API calls.
Control every provider through one policy layer
Applications authenticate once while Layer8 applies tenant, scope, rate, residency, model, and cost policy before a request reaches a provider. Provider credentials remain behind the control plane instead of spreading across applications and agent tools.
Routing can account for model capability, health, latency, budget, and data-handling requirements. Fallback is explicit and observable, so resilience does not become silent model substitution.
- Scoped API keys and tenant isolation
- Provider routing, failover, budgets, and quotas
- Normalized request, response, and streaming contracts
- Tenant-partitioned cache keys and structured audit records
Extend the gateway from transport to governed execution
A conventional LLM proxy ends when a model returns text. Layer8 can continue through specialist validation, bounded repair, calibrated gates, and human approval using the SALTI-B Engine.
That separation matters: the gateway owns secure execution, while the engine owns workflow control. Teams can adopt routing first and add deeper governance only where risk and value justify it.
Built for AI-first operations with accountable release
AI-first does not mean approval-free. Routine work can proceed automatically within measured policy. Uncertain, high-consequence, or poorly evidenced work can be held for human review with the full decision context attached.
Frequently asked questions
What is an AI gateway?
An AI gateway is a control layer between applications and AI providers. It centralizes authentication, model routing, rate limits, observability, cost controls, policy, and provider integrations.
How is Layer8 different from a basic LLM proxy?
Layer8 adds durable cascade execution, independent validation, bounded repair, human approval, tenant governance, and provenance beyond request forwarding.
Can Layer8 route to multiple AI providers?
Yes. The architecture supports policy-driven routing and fallback across approved providers while keeping credentials and audit data tenant-aware.
