Reliable, high-performance AI forwarding — purpose-built for developers
Every feature designed around the same goal: ship faster, pay less, never get stuck on a broken upstream.
100% OpenAI Compatible
Zero code change. Replace base_url with https://api.llmhigh.com/v1 and your existing OpenAI SDK works as-is — Python, Node, Go, anything that speaks the OpenAI API.
Global Edge Network
Distributed nodes across EU / US / APAC. 30–50% lower latency than direct upstream from most regions, with sub-100ms p50 for nearby users.
Multi-Instance Failover
Upstreams go down? We retry across sibling channels automatically. 99.95% uptime SLA on paid plans — zero customer-visible failures in the past three months.
50+ Models, 10+ Providers
OpenAI, Anthropic, Google, DeepSeek, Meta, Mistral, Alibaba, BAAI and more. New flagship models added within one week of community request.
Transparent Per-Token Billing
Flat 30% margin on top of upstream cost. No hidden fees, no monthly minimums, no tiered cliffs. Cost = tokens × published rate. See every line of the bill.
Built for Production
Per-key rate limits, real-time usage dashboard, request-level audit logs, AES-256-GCM encrypted key storage. Drop into Kubernetes and scale.
One endpoint, every flagship model
Pick from 50+ models across 10+ upstream providers — best-in-class for every task, billed transparently per token.
