OmniRoute architecture overview

Create a clean editorial technical diagram in 16:9 landscape format for a Chinese open-source project guide.

Show three coding tools on the left: Codex terminal, Claude Code terminal, and Cursor editor. Their requests converge into one locally hosted OmniRoute gateway in the center. Inside the gateway, clearly separate client authentication, model selection, automatic routing or Combo, health and quota checks, and fallback. On the right, show several distinct upstream model providers as neutral service blocks, with one selected route and two fallback routes. Make it visually clear that the gateway runs on the user's machine or own server while prompts still travel to the selected upstream provider.

Use a restrained professional palette with white or light gray background, charcoal text, green for the active route, amber for fallback, and muted blue for client connections. Avoid logos, gradients, decorative orbs, marketing claims, provider counts, tiny code, screenshots, and photorealistic elements. Use concise Simplified Chinese labels. Keep arrows unambiguous and leave enough spacing for legibility at article width.
