The decision to fine-tune a Large Language Model (LLM) requires careful evaluation of enterprise requirements. Let's explore key factors that influence this decision and how the LLM Fine-Tuning Evaluator helps assess them.

Quick video walkthrough on how to use the framework and decide on "should you be fine-tuning?"


Understanding When Fine-Tuning Becomes a Requirement


Privacy Considerations

Fine-tuning becomes essential when handling sensitive data such as:

  • Healthcare records requiring HIPAA compliance

  • Financial data with strict governance requirements

  • Intellectual property and trade secrets

  • Data subject to regional regulations like GDPR


Cost Factors

The $5,000 monthly API cost threshold often triggers fine-tuning considerations. A thorough cost analysis includes:

  • Current and projected token usage

  • Infrastructure and maintenance costs

  • ROI calculation based on break-even period

  • Long-term scalability requirements


Accuracy Needs

Fine-tuning becomes crucial when:

  • Task-specific accuracy falls below 85%

  • Critical errors exceed 2% of responses

  • Industry requirements demand high precision (e.g., 99%+ for medical applications)

  • Edge cases are frequently mishandled


Speed Requirements

Consider fine-tuning for:

  • Real-time applications needing sub-5-second responses

  • High-throughput processing systems

  • Time-sensitive operations like trading systems

  • Regular batch processing with strict deadlines

The 4 Ps to consider for fine-tuning


The Evaluation Framework

The tool scores each parameter on a 0-10 scale:


Privacy Score (0-10)

  • 0: No sensitive data handling

  • 5: Some confidential business data

  • 10: Highly regulated, sensitive personal data


Cost Score (0-10)

  • 0: API costs under $1,000/month

  • 5: API costs between $5,000-$15,000/month

  • 10: API costs exceeding $30,000/month


Accuracy Score (0-10)

  • 0: Current accuracy meets requirements

  • 5: Notable accuracy gaps exist

  • 10: Critical accuracy requirements unmet


Speed Score (0-10)

  • 0: No strict latency requirements

  • 5: Quick responses needed

  • 10: Real-time processing required


Decision Framework

The tool calculates a weighted score and gives a recommendation. This scoring is based on our extensive work with numerous enterprises and customizing more than 100 LLMs over the past year.

Based on the total score, you receive one of three recommendations:
