Overview
Inference Gateway is a high-performance, security-first data-plane service written in Go that serves as the single entry point for all production inference traffic. It authenticates every request, enforces per-tenant quotas, validates payloads, and forwards clean, enriched requests to the Neural Router, all at sub-millisecond overhead. Designed for zero-trust environments where every inference call must be accounted for, rate-limited, and auditable.
Capabilities
Multi-Layer Authentication
Supports API key, JWT, and mTLS authentication simultaneously. Every request is verified before it touches a model. No anonymous inference, ever.
Per-Tenant Quota Enforcement
Enforce rate limits per API key, per tenant, per endpoint, and per organization. Set daily token caps, concurrent request limits, and requests-per-second ceilings with automatic rejection and graceful degradation.
OpenAI-Compatible API
Drop-in replacement for OpenAI's API format. Migrate from OpenAI, Anthropic, or any provider without changing your client code. Support for chat completions, embeddings, and streaming (SSE).
Request Validation and Sanitization
Schema validation, size limit enforcement, content type checking, and input sanitization on every request. Malformed payloads are rejected before they reach the model.
Audit Logging and Metering
Every request is logged with request ID, trace ID, org ID, endpoint, latency, token count, and response status. Feed directly into billing systems, compliance audits, or usage dashboards.
Automatic Request Enrichment
Injects request ID, distributed trace ID, organization context, and service tier into every request before forwarding. Downstream services get full context without configuration.
Horizontal Scaling with Zero State
Stateless by design. Scale to thousands of instances behind a load balancer. No shared memory, no leader election, no coordination overhead.
Error Standardization
Consistent error response format across all failure modes: authentication failures, quota exhaustion, validation errors, upstream timeouts. Clients get actionable error codes, not generic 500s.
Endpoint Resolution and Routing Snapshots
Maps logical endpoint IDs to physical deployment targets using locally-cached routing snapshots pushed from the control plane. No database calls in the hot path.
Production-Grade Resilience
Panic recovery, graceful shutdown, connection draining, health probes, and readiness checks. Designed to survive node failures, rolling updates, and traffic spikes without dropping requests.
