Lightning Zeus
Cut AI inference spend with smart multi-model routing.
Lightning Zeus gives teams one OpenAI-compatible key for multiple model families, so routine work can run on efficient models while hard reasoning stays on frontier models.
Value message
Designed to deliver 3-4x better blended value than relying on one premium subscription or one expensive frontier API for every request.

One key. Multiple model families. Smarter routing.
Multi-model inference
Route routine work to efficient models and reserve frontier models for the hard calls.
OpenAI-compatible access
Drop into IDEs, agents, and SDKs that already support custom OpenAI-compatible endpoints.

Subscriptions can be great for individual interactive use; Lightning Zeus is built for API and agent workloads that need routing, observability, and model choice.
Spend less per outcome
Avoid sending every prompt to Opus, GPT-5.5, or a quota-bound subscription when an efficient model can do the job.
Keep frontier models available
Use premium models selectively for review, hard reasoning, and final answers instead of routine turns.
One endpoint for IDEs
Connect Claude Code, Codex, OpenClaw, Hermes, SDKs, and custom agents to the same gateway.
Use the right model for every request.
Start with one API key, check the available model list, and connect your IDE or agent stack to Lightning Zeus.
