When Fine-Tuning Makes Sense (And When It Doesn't)
Custom models aren't always the answer.
When Generic Models Fall Short
Prompt Engineering Overhead
Your prompts are 2,000 tokens of instructions. Small changes break everything.
Inconsistent Output
Sometimes the format is right, sometimes it's not. You can't rely on structure.
Domain Blindness
The model doesn't understand your industry terminology or concepts.
Cost at Scale
Long prompts mean high costs. You're paying for instructions every single call.
Latency Problems
Large prompts mean slow responses. Users notice the delay.
Privacy Concerns
You can't send sensitive data to generic APIs. You need more control.
What We Build
01
Training Data Preparation
The foundation of good fine-tuning.
●Data collection and curation
●Example generation and labeling
●Quality filtering and deduplication
●Format standardization
●Train/validation splitting
●Synthetic data augmentation
02
Fine-Tuning
Custom models for your needs.
●Open source model training (Llama, Mistral, Qwen)
●HuggingFace ecosystem deployment
●On-premises hosting for data sovereignty
●Classification and extraction models
●Style and format adaptation
●Domain-specific knowledge injection
03
Evaluation & Iteration
Measure and improve.
●Custom evaluation metrics
●A/B testing vs base models
●Error analysis and categorization
●Iterative improvement cycles
●Regression testing
●Production performance monitoring
04
Deployment & Hosting
Get your model into production.
●API endpoint deployment
●Self-hosted inference (for privacy)
●Scaling and load balancing
●Model versioning
●Rollback capabilities
●Cost optimization
Fine-Tuned vs Prompted
| Prompt Engineering | Fine-Tuning |
|---|---|
| Long, complex prompts | Short, simple prompts |
| Inconsistent formatting | Reliable structure |
| Generic understanding | Domain expertise baked in |
| High per-call cost | Lower inference cost |
| Slow responses | Faster generation |
Best For
Teams and organizations who have:
→High-volume, repetitive AI tasks
→Specific output format requirements
→Domain-specific terminology or knowledge
→Long prompts eating into costs
→Consistency issues with current approach
→Training examples or ability to create them
