Xenith LLM Platform
Model routing, caching, and cost controls between your apps and every LLM provider.
Xenith LLM Platform is a model gateway that sits between your applications and every LLM provider (OpenAI, Anthropic, Google, and open-weight models on vLLM). It routes each request to the cheapest model that passes the eval threshold for that task, caches repeated prompts, enforces per-team keys and quotas, and logs prompts and outputs for audit. We deploy it in your account and hand over the routing rules and dashboards.
Routes across GPT-4o, Claude 3.5, Gemini, Llama, and Mistral. Best model for every task.
Deployed as a scoped engagement for your stack - not a self-serve trial or live sandbox.

How it works
- Intelligent routing: cheap models for simple tasks, powerful models for complex ones
- Semantic caching: identical or near-identical queries served from cache
- Cost optimisation engine with real-time spend dashboard
- Prompt versioning and A/B testing built in
- Observability: latency, cost, and accuracy per model, per endpoint
