OpenRouter
Stop being locked into a single LLM. Your AI agent picks the right model for every customer question through OpenRouter, whether it needs GPT-4 for reasoning or a fast model for simple lookups. Smarter answers, lower costs, zero vendor lock-in.
Your AI agent dynamically selects from hundreds of language models, generates completions, and monitors usage, all through a single unified API endpoint.
OpenRouter
See how businesses use AI agents with OpenRouter to match every customer interaction to the best-fit language model, optimizing quality and cost simultaneously.
A customer asks a simple FAQ. Your AI Agent checks the question complexity, selects a lightweight model through OpenRouter for fast, inexpensive inference, and delivers the answer in under a second. Complex questions automatically route to a premium model. You get GPT-4-level quality only when you need it, cutting AI costs by up to 70% without customers noticing any difference.
A customer writes in Japanese. Your AI Agent queries OpenRouter's model catalog, finds a model optimized for Japanese language understanding, and generates the response through that model. The next customer writes in Spanish, and the agent seamlessly switches. One integration handles every language through the best-fit model.
Your primary LLM provider experiences an outage during peak hours. Your AI Agent detects the failure and automatically falls back to an alternative provider through OpenRouter's distributed infrastructure. Customers never see an error message. Your support stays online while competitors scramble.

FAQs
OpenRouter provides access to over 400 models from providers including OpenAI (GPT-4, GPT-4o), Anthropic (Claude), Google (Gemini), Meta (Llama), Mistral, and many more. The agent can query the model catalog in real time and select the best model for each specific task or conversation type.
You configure the routing logic. Set rules like 'use GPT-4o for complex reasoning, use Llama for simple FAQs, use Claude for long documents.' The agent follows your rules and can also check model availability and pricing dynamically before each call through OpenRouter's model and endpoint APIs.
OpenRouter's distributed infrastructure automatically falls back to alternative providers. If OpenAI is experiencing latency, your agent transparently routes to another provider hosting the same or equivalent model. Customers never see an error or interruption in the conversation.
OpenRouter passes through the pricing of underlying providers. You pay the same per-token rate you would pay directly, with a small platform fee. The agent can check your credit balance before calls and switch to cheaper models if budget constraints are tight, giving you granular cost control.
Yes. OpenRouter supports Bring Your Own Key (BYOK) mode, where you use your existing provider API keys routed through OpenRouter's unified interface. The first million BYOK requests per month are free, making it cost-effective to consolidate your existing keys under one API.
Tars processes prompts and responses in real time during conversations. OpenRouter offers Zero Data Retention (ZDR) options and custom data policies, so you can control whether any provider sees or stores your prompt data. Configure these settings through your OpenRouter dashboard.
Absolutely. The agent can call OpenRouter's chat completion endpoint multiple times within a single conversation, using different models each time. A product lookup might use a fast, cheap model while a nuanced complaint gets routed to a premium reasoning model, all seamlessly.
Direct provider connections lock you into one model and one pricing structure. OpenRouter gives your agent access to every major model through one API key, with automatic failover, competitive pricing, and the flexibility to switch models without changing any code or configuration.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
