Node.js In-App Chatbot LLM API: Moderation Quality Gates Before Review

For Node.js in-app chatbots classifying game reports, select LLM APIs based on policy floor quality and p95 latency to fit review queues. A routing contract should manage ordinary reports, ambiguous evidence, and abstentions. Regarding general comparisons, Claude 3.5 Sonnet is ideal for high conversational quality, while GPT-4o-mini suits budget-conscious deployments. Gemini 1.5 Pro serves as a middle option. All three support streaming, making user-visible wait times a product decision rather than just a model benchmark.
