How LLM Gateways Slash AI Spend by up to 80%

The cost of running AI applications has become a critical concern for businesses of all sizes. With OpenAI's ChatGPT alone costing approximately $700,000 per day to operate, it's no wonder that companies are desperately seeking ways to reduce their AI expenses without sacrificing performance.

Enter LLM gateways – the game-changing middleware that's helping organizations cut their AI costs by 30-80% while actually improving their AI operations. At Requesty, we've seen firsthand how our unified LLM gateway has helped over 15,000 developers achieve these dramatic savings through intelligent routing, caching, and optimization.

Let's dive into exactly how LLM gateways deliver these remarkable cost reductions and why they've become essential infrastructure for any serious AI deployment.

Understanding LLM Gateways: Your AI Cost Control Center

An LLM gateway acts as a smart middleware layer between your applications and various AI models. Think of it as a highly intelligent traffic controller that not only routes your requests to the right model but also optimizes every aspect of that journey to minimize costs.

Unlike direct API connections to individual providers, a gateway like Requesty provides:

  • Unified access to 160+ models through a single API

  • Intelligent routing based on cost, performance, and availability

  • Built-in caching to avoid redundant API calls

  • Automatic failover to ensure reliability

  • Centralized cost tracking and optimization

This centralization creates what experts call a "cost-optimization flywheel" – where every optimization compounds to deliver increasingly better savings over time.

The 7 Key Ways LLM Gateways Cut Costs

1. Token Caching: Up to 90% Savings on Repeated Queries

One of the most powerful cost-saving features of LLM gateways is intelligent caching. When multiple users or processes make similar requests, the gateway can serve cached responses instead of making expensive API calls.

Requesty's caching system automatically identifies cacheable content and can reduce costs by up to 90% for frequently repeated queries. This is particularly valuable for:

  • Common customer service questions

  • Standardized document processing

  • Repeated analysis tasks

  • System prompts and templates

2. Smart Model Selection: 80% Savings Through Intelligent Routing

Not all AI tasks require the most expensive models. A gateway with smart routing capabilities automatically selects the most cost-effective model for each specific task.

For example:

  • Simple text classification might use a lightweight model costing $0.0001 per 1K tokens

  • Complex reasoning tasks might require GPT-4o at $5 per 1M tokens

  • Code generation might leverage DeepSeek at 80% lower cost than comparable models

Requesty's smart routing analyzes your request and automatically routes it to the optimal model, ensuring you never overpay for simple tasks.

3. Batch Processing: 50% Cost Reduction for Bulk Operations

Many LLM providers offer significant discounts for batch processing. A well-designed gateway consolidates multiple requests into batches, achieving up to 50% cost savings for non-real-time operations like:

  • Bulk content generation

  • Large-scale data analysis

  • Embedding generation for vector databases

  • Translation of document libraries

4. Fallback Policies: Never Overpay During Outages

When a primary model experiences issues or rate limits, direct API connections often fail completely. Requesty's fallback policies automatically route to alternative models, ensuring:

  • Continuous service availability

  • Automatic selection of the next most cost-effective option

  • No manual intervention required

  • Protection against price surges or outages

5. Request Optimization: 30% Savings Through Smart Formatting

LLM gateways can automatically optimize your prompts and requests to minimize token usage:

  • Remove unnecessary whitespace and formatting

  • Convert verbose JSON to efficient CSV formats

  • Compress context windows intelligently

  • Implement prompt templates that minimize token count

These optimizations typically reduce costs by 20-30% with zero impact on output quality.

6. Model Compression and Optimization

Advanced gateways support compressed models and optimization techniques that can reduce inference costs by 50-80%:

  • Quantization reduces model precision without significant accuracy loss

  • Pruning removes unnecessary model parameters

  • Distillation creates smaller, faster models from larger ones

Requesty's dedicated models for specific applications like coding assistants leverage these techniques to deliver premium performance at fraction of the cost.

7. Centralized Cost Management and Governance

Perhaps the most underappreciated benefit is centralized cost control. Requesty's enterprise features provide:

  • Per-user and per-team spend limits

  • Real-time cost tracking and alerts

  • Detailed analytics on model usage patterns

  • API key-level budgets and controls

This visibility alone often leads to 15-40% cost reductions as teams become more aware of their AI spending patterns.

Real-World Success Stories
