Your AI is costing more than you realize

Models don't read words — they read tokens, small chunks of text (about 4 characters, or ¾ of a word). Providers bill per million tokens, so the length of your prompts and responses directly sets your cost. Simple requests rarely need the most expensive model.

Routing sends each request to the model best suited to that task — a fast, cheap model for simple queries, a stronger one for hard problems. Instead of paying one premium model for everything, you pay each model only for the work it's good at. Xilos does this automatically at request time.

Your prompt travels to a provider, where a model generates a response token by token. Everything in it — context, examples, data — is sent as-is to that provider. Having visibility into what's sent, what it costs, and where it goes is the layer most teams are missing.

Names, emails, phone numbers, credentials, source code, financials — anything that shouldn't leave your control. If it's in your prompt, a public API sees it. Xilos detects and blocks PII before it reaches a provider, and can route sensitive work to governed or self-hosted models.
