Use Cases

12 production-ready AI use cases with complete implementation examples

Practical examples and production-ready patterns for common AI integration scenarios

Overview

This guide showcases 12+ real-world use cases demonstrating how to build production-ready AI applications with NeurosLink AI. Each use case includes complete implementation code, cost optimization strategies, and best practices.

1. Customer Support Automation

Scenario: Automated customer support with multi-provider failover and cost optimization.

Architecture

User Query → Intent Classification → Route to:
  - FAQ Bot (Free Tier: Google AI)
  - Complex Support (GPT-4o)
  - Escalation (Human Agent)

Implementation

import { NeurosLink AI } from "@raisahai/neurolink";

class CustomerSupportBot {
  private ai: NeurosLink AI;

  constructor() {
    this.ai = new NeurosLink AI({
      providers: [
        {
          name: "google-ai-free",
          priority: 1,
          config: {
            apiKey: process.env.GOOGLE_AI_KEY,
            model: "gemini-2.0-flash",
          },
          quotas: { daily: 1500 },
        },
        {
          name: "openai",
          priority: 2,
          config: {
            apiKey: process.env.OPENAI_API_KEY,
            model: "gpt-4o-mini",
          },
        },
      ],
      failoverConfig: { enabled: true, fallbackOnQuota: true },
    });
  }

  async classifyIntent(query: string): Promise<"faq" | "complex" | "escalate"> {
    const result = await this.ai.generate({
      input: {
        text: `Classify customer support intent:
Query: "${query}"

Return only one word: faq, complex, or escalate`,
      },
      provider: "google-ai-free",
    });

    const intent = result.content.toLowerCase().trim();
    return ["faq", "complex", "escalate"].includes(intent)
      ? (intent as any)
      : "complex";
  }

  async handleFAQ(query: string): Promise<string> {
    const result = await this.ai.generate({
      input: {
        text: `Answer this FAQ question concisely:
${query}

Use our knowledge base:
- Returns: 30-day return policy
- Shipping: 3-5 business days
- Payment: Credit card, PayPal accepted`,
      },
      provider: "google-ai-free",
      model: "gemini-2.0-flash",
    });

    return result.content;
  }

  async handleComplexQuery(
    query: string,
    conversationHistory: string[],
  ): Promise<string> {
    const result = await this.ai.generate({
      input: {
        text: `You are a helpful customer support agent.

Conversation history:
${conversationHistory.join("\n")}

Customer: ${query}

Provide a detailed, helpful response.`,
      },
      provider: "openai",
      model: "gpt-4o",
    });

    return result.content;
  }

  async processQuery(
    query: string,
    conversationHistory: string[] = [],
  ): Promise<{
    response: string;
    intent: string;
    escalated: boolean;
  }> {
    const intent = await this.classifyIntent(query);

    if (intent === "escalate") {
      return {
        response:
          "I've escalated your request to a human agent. They'll be with you shortly.",
        intent,
        escalated: true,
      };
    }

    const response =
      intent === "faq"
        ? await this.handleFAQ(query)
        : await this.handleComplexQuery(query, conversationHistory);

    return { response, intent, escalated: false };
  }
}

const supportBot = new CustomerSupportBot();

const result = await supportBot.processQuery("What is your return policy?");

Cost Analysis:

FAQ queries (80%): Free tier (Google AI)
Complex queries (18%): $0.15 per 1M input tokens (GPT-4o-mini)
Escalations (2%): Human agent
Total savings: 90% vs. using GPT-4o for all queries

2. Content Generation Pipeline

    });

    return result.content;

Return JSON:

  "tags": ["tag1", "tag2", "tag3"]
}`,
      },
      provider: "openai",
      model: "gpt-4o-mini",
    });

    return JSON.parse(result.content);
  }

  async generateComplete(
    topic: string,
    keywords: string[],
  ): Promise<{
    content: string;
    metadata: any;
    seoScore: number;
  }> {
    const draft = await this.generateDraft(topic, keywords);
    const improved = await this.improveDraft(draft);
    const seoResult = await this.optimizeSEO(improved, keywords);
    const metadata = await this.generateMetadata(seoResult.content);

    return {

Cost Optimization Patterns

Pattern 1: Free Tier First

const ai = new NeurosLink AI({
  providers: [
    {
      name: "google-ai",
      priority: 1,
      config: { apiKey: process.env.GOOGLE_AI_KEY },
      quotas: { daily: 1500 },
    },
    {
      name: "openai",
      priority: 2,
      config: { apiKey: process.env.OPENAI_API_KEY },
    },
  ],
  failoverConfig: { enabled: true, fallbackOnQuota: true },
});

Savings: 80-90% cost reduction

Pattern 2: Model Selection by Complexity

async function chooseModel(task: string): Promise<string> {
  const complexity = await classifyComplexity(task);

  return complexity === "simple" ? "gpt-4o-mini" : "gpt-4o";
}

Savings: 60-70% cost reduction
