Case Study: How E-commerce Chatbots Scale to Black Friday Traffic with Requesty

Black Friday 2024 saw a staggering $9.8 billion in online sales, with 71% of consumers shopping digitally and 70% of transactions happening on mobile devices. For e-commerce businesses, this massive surge in traffic presents both an incredible opportunity and a daunting challenge: how do you scale customer support and sales assistance when traffic increases 10x overnight?

The answer lies in AI-powered chatbots – but not just any chatbots. Success requires intelligent routing, seamless failover, and cost optimization to handle millions of simultaneous conversations without breaking the bank. This case study explores how leading e-commerce brands leverage Requesty's unified LLM gateway to power their Black Friday chatbot operations at scale.

The Black Friday Challenge: Scale, Speed, and Cost

E-commerce businesses face a perfect storm during Black Friday:

  • Traffic Surge: Website visits and customer inquiries can increase by 1000% or more

  • Response Time Pressure: Customers expect instant answers or they'll shop elsewhere

  • Cost Constraints: Traditional scaling methods (hiring seasonal staff) are expensive and inefficient

  • Technical Complexity: Managing multiple AI models and ensuring uptime becomes critical

Modern chatbots powered by LLMs like GPT-4o, Claude 4, and DeepSeek R1 can handle these challenges – but only if they're properly optimized and managed. That's where intelligent routing and optimization become essential.

How Smart Routing Transforms Black Friday Performance

Requesty's smart routing technology automatically selects the best AI model for each customer interaction, balancing performance, cost, and availability. Here's how it works in practice:

Intelligent Model Selection

During Black Friday, not every customer query requires the most expensive AI model. Smart routing analyzes each request and routes it appropriately:

  • Simple product availability questions → Cost-efficient models like GPT-3.5

  • Complex sizing or compatibility queries → Advanced models like Claude 4

  • Technical support issues → Specialized models optimized for problem-solving

This approach can reduce AI costs by up to 80% while maintaining high-quality responses.

Real-Time Failover

When handling millions of requests, model availability becomes critical. Requesty's routing optimizations include automatic failover policies that ensure conversations never drop:

  • Primary model experiences high latency → Instantly switch to backup

  • Rate limits reached → Distribute load across multiple providers

  • Model downtime → Seamless transition with no customer impact

One major electronics retailer reported 99.99% uptime during Black Friday 2024 using Requesty's failover system, compared to 94% uptime the previous year with a single-provider setup.

Case Study: Fashion Retailer Scales to 2M Conversations

A leading fashion e-commerce brand faced a critical challenge: their Black Friday 2023 chatbot system crashed under load, resulting in $1.2M in lost sales. For 2024, they implemented Requesty's unified gateway with the following results:

The Implementation

  • Models Used: Mix of GPT-4o, Claude 4, and GPT-3.5 via Requesty's 160+ model catalog

  • Smart Routing Rules: Complex queries to Claude 4, simple FAQs to GPT-3.5

  • Caching Strategy: Common questions cached for instant response

  • Failover Chain: Primary → Secondary → Tertiary model configuration

The Results

  • Conversations Handled: 2.1 million (up from 500K capacity in 2023)

  • Average Response Time: 1.2 seconds (down from 4.5 seconds)

  • Cost Per Conversation: $0.003 (down from $0.015)

  • Customer Satisfaction: 92% positive ratings

  • Revenue Impact: $3.4M in chatbot-assisted sales

The key to their success was Requesty's caching and failover system, which served 60% of responses from cache, dramatically reducing both costs and latency.

Technical Architecture for Black Friday Scale

Building a Black Friday-ready chatbot system requires careful architecture planning. Here's the proven approach using Requesty:

Core Components

1. Unified API Gateway Instead of managing multiple AI provider APIs, all requests route through Requesty's single endpoint. This simplifies development and enables advanced optimizations.

2. Load Balancing Requesty's load balancing distributes requests across multiple model instances, preventing any single point of failure.

3. Intelligent Caching Common queries like "What are your return policies?" or "Do you ship to Canada?" are cached and served instantly, reducing load on AI models.

4. Security Guardrails Enterprise-grade security features protect against prompt injection attacks and ensure PCI compliance for payment-related queries.

Integration Example

Here's how a typical e-commerce chatbot integrates with Requesty:

```python

Simple integration with Requesty's OpenAI-compatible API

from openai import OpenAI

client = OpenAI( api_key="your-requesty-api-key", base_url="https://api.requesty.ai/v1" )

Requesty automatically handles routing, caching, and failover

response = client.chat.completions.create( model="auto", # Let smart routing choose the best model messages=[ {"role": "system", "content": "You are a helpful shopping assistant."}, {"role": "user", "content": customer_query} ], metadata={"channel": "black-friday", "priority": "high"} ) ```

Cost Optimization Strategies That Actually Work

The biggest surprise for many e-commerce teams is how much they can save on AI costs without sacrificing quality. Here are proven strategies:

1. Implement Tiered Model Usage

Not every conversation needs GPT-4o or Claude 4. By using Requesty's smart routing, you can:

  • Route 70% of simple queries to cost-efficient models

  • Reserve premium models for complex product recommendations

  • Use specialized models for specific tasks (e.g., dedicated coding models for technical products)

2. Aggressive Caching

Black Friday queries are highly repetitive. Caching can handle:

  • Product availability checks

  • Shipping information

  • Return policies

  • Promotion details

One retailer reduced their AI costs by 85% by caching the top 100 most common queries.

3. Set Spend Limits

Requesty's API spend limits prevent runaway costs during traffic spikes. You can set:

  • Daily spending caps

  • Per-conversation limits

  • Model-specific budgets

4. Use Your Own Keys

For high-volume operations, bring your own API keys to access volume discounts while still benefiting from Requesty's routing and optimization.
