OpenRouter
OpenRouter app builder.
Multi-model AI apps.
Connect your OpenRouter API key and build multi-model agents that route to the best model for each task — deployed to live URLs with persistent infrastructure.
Access the entire AI ecosystem.
OpenRouter gives you a single API key to every major AI model. camelAI gives you the infrastructure to build with all of them.
Build agents that pick the right model for each step.
Why use one model for everything? Your agents can route each subtask to the optimal model — balancing cost, speed, and quality automatically.
Classify intent
Fast classification doesn't need frontier reasoning
Deep analysis
Complex reasoning requires the most capable model
Generate response
Balanced speed and quality for user-facing output
What developers build with OpenRouter + camelAI.
Smart routing chatbot
Fast model for simple queries, powerful model for complex reasoning. Your chatbot picks the right model per message automatically.
Model A/B testing playground
Send the same prompt to multiple models, compare outputs side-by-side, and run automated evals. Find the best model for your use case.
Cost optimizer dashboard
Track per-token costs across providers in real time. Visualize spend by model, by task, and spot opportunities to swap in cheaper alternatives.
Multi-model agent pipeline
Chain models for complex workflows — summarize with one, analyze with another, generate with a third. Each step uses the optimal model.
Your agents use the cheapest model that clears the quality bar.
Not every task needs the most expensive model. Smart routing saves 60–80% on API costs without sacrificing output quality.
| Model | Input/1M | Output/1M | |
|---|---|---|---|
GPT-4o OpenAI | $2.50 | $10.00 | |
Claude 3.5 Sonnet Anthropic | $3.00 | $15.00 | |
Llama 3.3 70B Meta | $0.18 | $0.18 | Best value |
Mistral Large Mistral | $2.00 | $6.00 |
For classification tasks, Llama 3.3 70B achieves 94% of GPT-4o accuracy at 7% of the cost.
You build the agent. We handle everything else.
OpenRouter gives you model access. camelAI gives you the infrastructure. You focus on agent logic.

What will you build with every model at your fingertips?
“Connect to OpenRouter and build a multi-model agent that classifies incoming support tickets with Llama, drafts responses with GPT-4o, and reviews them with Claude before sending.”
Try this prompt“Create a model A/B testing dashboard. Let me paste a prompt, send it to 5 different models simultaneously, and compare outputs side-by-side with latency and cost metrics.”
Try this prompt“Build a cost-per-token optimizer that monitors my OpenRouter usage, shows spend by model and task type, and recommends cheaper alternatives when quality scores are comparable.”
Try this prompt“Set up a smart chatbot that routes simple questions to Llama 3.3 and complex reasoning tasks to Claude Opus. Track which model handles each query and the cost savings.”
