Solution #2: LLM Customization, Demystified

RAG or Fine-Tuning? We'll Tell You Which (And Why).

Stop guessing about LLM architecture. Our data-driven framework analyzes your specific use case to recommend the optimal approach—saving you months of trial and error.

Our Decision Framework

We analyze four key factors to recommend the optimal approach

FactorRAGFine-TuningOur Recommendation
Data VolumeWorks with any amount of dataRequires 1,000+ high-quality examplesRAG if you have <1,000 examples
Update FrequencyReal-time updates, no retrainingRequires retraining for updatesRAG for frequently changing data
Response Accuracy85-92% accuracy with good retrieval90-95% accuracy when done rightFine-tuning for mission-critical accuracy
Cost Structure$0.10-0.50 per 1K queries$500-5K upfront + $0.05 per 1KRAG for <10K queries/month

RAG vs. Fine-Tuning: Complete Breakdown

Both approaches have their place. The key is choosing the right one for your specific situation.

RAG (Retrieval-Augmented Generation)

Combines your data with a pre-trained model in real-time

Cost: $500-2,000/month
Timeline: 2-4 weeks

Best For:

Frequently updated content
Large knowledge bases
Quick implementation

Advantages

  • No training required
  • Real-time data updates
  • Lower upfront costs
  • Transparent reasoning
  • Works with small datasets

Limitations

  • Higher per-query costs
  • Dependent on retrieval quality
  • Potential latency issues
  • Limited customization

Fine-Tuning

Train a model specifically on your data and use cases

Cost: $5,000-25,000 upfront
Timeline: 6-12 weeks

Best For:

Specialized domains
Consistent formatting
High accuracy needs

Advantages

  • Highest accuracy potential
  • Lower per-query costs
  • Complete customization
  • Faster inference
  • No external dependencies

Limitations

  • High upfront investment
  • Requires quality training data
  • Longer development time
  • Difficult to update

Avoid These Costly LLM Mistakes

We've seen these mistakes cost companies 6+ months and $50K+ in wasted development.

Choosing Based on Hype

The Problem

Following trends instead of analyzing your specific use case

Our Solution

Use our data-driven decision framework

Impact

Avoid 6-month rebuilds and wasted budget

Underestimating Data Quality

The Problem

Assuming any data will work for fine-tuning

Our Solution

Comprehensive data audit and preparation

Impact

Achieve 90%+ accuracy from day one

Ignoring Operational Costs

The Problem

Only considering development costs, not ongoing expenses

Our Solution

Full TCO analysis over 12-24 months

Impact

Avoid budget surprises and cost overruns
