Auto-Switch Control Panel

The Auto-Switch sidebar tab opens the control panel — the place to change routing behavior. Direct URL: https://router.cocolevio.com/autoswitch/.

What you can change

Control	Effect
Classifier	The judge model that reads prompts and picks tiers
SIMPLE / MEDIUM / COMPLEX / REASONING	The model pool per tier — one model id per line, top = highest priority

The input boxes autocomplete with a curated list (ultra-cheap, free, mid, strong, and reasoning models), but any model id the gateway knows is valid — OpenRouter ids (openrouter/author/model), direct provider ids (gpt-4o, gemini/gemini-2.5-flash), or Bedrock ids (bedrock/…).

Applying changes

Click Save changes. The config is written to the shared tiers.json and the router hot-reloads it on the next request — no restart, no deploy, applies within one second. The panel confirms with "✓ Saved — live now".

Free models: what to expect

OpenRouter :free models cost $0 but are heavily rate-limited (429s under any real traffic). The recommended pattern, and the shipped default for SIMPLE, is free-first with paid fallback:

openrouter/meta-llama/llama-3.3-70b-instruct:free   ← $0 when available
openrouter/meta-llama/llama-3.1-8b-instruct          ← $0.02/$0.03 per M when not
openrouter/google/gemini-2.5-flash-lite              ← second backup
