Could you build this?
Partial A basic LLM proxy can be vibe-coded, but an enterprise-ready AI gateway needs high-throughput, sub-millisecond streaming proxy architecture, reliable failover, and zero-latency token tracing.
What it would actually take: A viable AI proxy must be built on high-performance runtimes such as Go, Rust, or optimized Node.js, utilizing streaming HTTP reverse-proxying with minimal overhead. It requires precise streaming token-counting algorithms (like tiktoken ported natively), distributed rate-limiting (Redis token bucket), automated failover/retry logic across LLM providers, and real-time PII redacting/guardrail pipelines without adding unacceptable latency. Deep knowledge of networking, concurrent streaming I/O, and production observability architecture is necessary.
