The AI That Picks the Right AI
One API. 50+ models. Automatic routing to the optimal model for every task. Cut costs by 90% without sacrificing quality.
The Problem Every AI Business Faces
Using a single AI provider means compromising on cost, speed, or quality.
$60/1M tokens for GPT-4. Slow at 60 tok/s. No EU-hosted option. US CLOUD Act applies.
$75/1M tokens for Opus. Great quality but expensive. No speed tier. US jurisdiction.
Cheaper but inconsistent quality. Limited model selection. Google data policies.
50+ models from every provider. Automatic selection based on task, language, speed needs, and compliance requirements. From $0 to $75/1M tokens - you only pay for what you need.
5-Dimensional Intelligent Routing
Every request is analyzed across 5 dimensions to select the optimal model.

Frequently Asked Questions
Common questions about the Intelligent LLM Router
What is an LLM API router?
An LLM API router is a service that automatically routes your AI requests to the optimal model among multiple providers. Instead of calling a single API like OpenAI, you call WorkChi, which analyzes your request and routes it to the best model based on cost, speed, quality, language, and compliance requirements.
How much can I save using an LLM router?
Most customers save 60-90% on their AI costs. Simple tasks are routed to free or low-cost models like Cloudflare Workers AI, while complex tasks use premium models like GPT-4 or Claude. The exact savings depend on your workload mix.
Is the API compatible with existing code?
Yes! The WorkChi API is fully compatible with the OpenAI API format. Simply change the base URL to https://api.workchi.ai/v1 and use 'auto' as the model name. All existing OpenAI SDKs, LangChain, and LlamaIndex integrations work out of the box.
Are EU-hosted options available?
Yes. We offer EU-hosted models through Nebius (Frankfurt, Amsterdam) and Cloudflare's EU edge network. These options are CLOUD Act immune and GDPR compliant, making them ideal for regulated industries and EU-based companies.
What models are available through the router?
We support 50+ models including GPT-4o, Claude 4, Gemini 2.5, DeepSeek R1, Qwen3, Llama 3.3, and many more. The router automatically selects the best model for each specific task type and language.
