ハイブリッドマルチLLM Ghost Operatorによる自律型AIモデレーション

スパム排除、フィッシング対策、50ms未満でのコミュニティ質疑応答を実現する自律型AIオペレーターの構築と運用。

1. The Failure of Regex and Rule-Based Auto-Moderation

Traditional Discord and Telegram bots rely on keyword blocklists and regex patterns. Malicious actors easily bypass these with zero-width Unicode characters, homoglyphs, and evasive URL shorteners.

Ghost Operators utilize hybrid embedding analysis and fast LLM classification to detect malicious intent semantically, regardless of character obfuscation.

2. Hybrid Dynamic Routing: Sub-50ms Classification with Fallbacks

Large language models (like Gemini 1.5 Pro or GPT-4o) introduce 800ms–2000ms latency—unacceptable for real-time chat moderation. SovereignPatron implements a 2-Tier Pipeline:

• Tier 1: Ultra-fast edge classification (<30ms) for high-confidence spam and link sanitization.

• Tier 2: Asynchronous vector retrieval and multi-LLM reasoning for complex member inquiries and community support.

lib/ai/moderation-router.tstypescript
export async function evaluateMessageRisk(
  content: string,
  authorId: string,
  accountAgeDays: number
): Promise<{ action: 'ALLOW' | 'QUARANTINE' | 'BAN'; reason?: string }> {
  // Fast Path: New accounts posting external URLs
  const hasUrl = /https?:\/\/[^\s]+/i.test(content);
  if (accountAgeDays < 1 && hasUrl) {
    return { action: 'QUARANTINE', reason: 'High Risk: Zero-day account link sharing' };
  }

  // Tier 1 Fast Semantic Analysis
  const riskScore = await fastEmbeddingClassification(content);
  if (riskScore > 0.85) {
    return { action: 'BAN', reason: 'Malicious payload / coordinated raid signature' };
  }

  return { action: 'ALLOW' };
}

3. Autonomous Knowledge Base Synthesis

Ghost Operators continuously ingest past announcements, documentation, and resolved tickets to answer recurring community questions with grounded citations, freeing community managers from repetitive support tasks.

Frequently Asked Questions

Can Ghost Operators handle multi-language community channels?

Yes. Ghost Operators natively support 9+ languages (English, French, Spanish, German, Portuguese, Russian, Turkish, Japanese, Korean) and detect member language dynamically per message.

What safety mechanisms prevent AI hallucinations in public channels?

Ghost Operators enforce strict Retrieval-Augmented Generation (RAG) grounding with temperature thresholds below 0.2, quoting verified documentation directly.
