Overview

Prompt engineering is one of the most accessible ways to reduce AI costs. By optimizing how you communicate with AI models, you can achieve 8-15% cost reductions while often improving output quality.

Core Techniques

1. Concise Instruction Writing

❌ Verbose (98 tokens)

"Could you please help me by providing a comprehensive and detailed explanation of the various methods and approaches that can be used to improve writing skills, including specific techniques and strategies?"

✅ Concise (12 tokens)

"List 5 effective writing improvement techniques."

Savings: 87% token reduction without losing clarity

2. Format Optimization

Choose output formats that minimize token usage. CSV format typically uses fewer tokens than JSON for structured data.

❌ JSON (45 tokens)

{ "products": [ {"name": "Widget A", "price": 10}, {"name": "Widget B", "price": 15} ] }

✅ CSV (22 tokens)

Product,Price Widget A,10 Widget B,15

Savings: 51% token reduction for structured data

3. Context Management

Only include relevant context. Remove unnecessary background information that doesn't directly impact the output.

Advanced Optimization

Batch Processing

Process multiple items in a single request instead of separate calls. This eliminates repeated instruction overhead.

Example: Document Analysis

Individual requests: 300K tokens for 10 documents

Batch request: 210K tokens for same 10 documents

Savings: 30% reduction by eliminating repeated instructions

Implementation Checklist

Review all prompts for unnecessary words and phrases
Standardize output formats to token-efficient structures
Implement batch processing for similar tasks
Monitor token usage before and after optimization
Document successful patterns for team consistency
