Setting Up Kimi K3 & Grok 4.5 Proxies for Janitor AI via MegaNova

If you've been using Janitor AI's default language models (such as JanitorLLM), you already know how creative custom AI roleplay can be. However, pairing Janitor AI with next-generation frontier models—like Moonshot AI's Kimi K3 and xAI's Grok 4.5—takes immersion, roleplay fidelity, and complex scenario handling to a whole new level.

Using MegaNova as your proxy routing provider, you can connect these flagship models directly to your Janitor AI characters with minimal latency and custom model parameters.

To get the most lifelike responses out of both models in Janitor AI, adjust your Generation Parameters under Chat Settings:

  • Temperature:
    • Kimi K3: Set between 0.7 and 0.85 for logical narrative flow without repetition.
    • Grok 4.5: Set between 0.85 and 1.05 for creative, unpredictable dialogue.
  • Max Output Tokens: Set to 400–800 tokens per reply. This keeps character responses at a natural roleplay length (2–4 detailed paragraphs).
  • Presence & Frequency Penalty: Keep around 0.1–0.3 to prevent the AI from repeating signature phrases or character dialogue loops.

Troubleshooting Common Setup Issues

  • 401 Unauthorized / Invalid API Key: Double-check your MegaNova key for accidental leading or trailing spaces.
  • 404 Not Found / Empty Replies: Ensure the Model Name string matches the exact model identifier specified in the MegaNova console. Also check that your Proxy URL ends with /chat/completions.
  • Truncated Replies: Increase your Max Output Tokens slider in Janitor AI's Generation Settings.
