Built for Developers, by Developers
Everything you need to build with LLMs — unified, optimized, and ready for production.
Unified API
One endpoint for every model. Same request format, same response format. Switch models with a single line change.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api.openllms.org/v1",
apiKey: process.env.OPENLLMS_API_KEY,
});
// Works with any model - GPT, Claude, Qwen, DeepSeek...
const response = await client.chat.completions.create({
model: "gpt-5.5", // or "claude-opus-4-8", "qwen3.7-max"
messages: [{ role: "user", content: "Hello!" }],
});Lightning Fast
Global edge network with <50ms average latency. Automatic routing to the nearest provider.
Cost Optimized
Intelligent routing finds the cheapest path. Prompt caching reduces costs further.

Powering the Next Generation of AI Applications
From solo developers to enterprise teams, thousands rely on OpenLLMs to ship AI-powered products faster.
“OpenLLMs cut our integration time from weeks to hours. One API key, every model we need — including DeepSeek and Qwen which were hard to access before.”
Sarah Chen
CTO, NeuralFlow AI
“We reduced our LLM costs by 60% by routing traffic through OpenLLMs' intelligent cost optimization. The automatic failover is a game-changer for production reliability.”
Marcus Rodriguez
Lead Engineer, DataPulse
“Having both GPT-5 and Qwen3.7 available through the same endpoint means our team can A/B test models instantly without any code changes.”
Aiko Tanaka
VP of Engineering, CogniTech Labs
“We migrated 200+ microservices to OpenLLMs in a single weekend. The OpenAI-compatible API meant zero code changes — just swapped the base URL.”
David Park
Principal Architect, Skyline Systems
“The Chinese model access is a game changer. We now serve Qwen and DeepSeek to our APAC users with sub-30ms latency, without managing separate accounts.”
Wei Zhang
Head of AI, OmniTech Solutions
“Our AI-powered code review tool runs 15 different models through OpenLLMs. The prompt caching alone saves us $12K per month on inference costs.”
