FAQs

Frequently Asked Questions

Almost always fine-tune. Training from scratch requires billions of tokens and millions in compute. Fine-tuning a strong base model (Llama 3, Mistral) on your domain data delivers superior results in days, not months.

It depends on model size. 7B parameter models run on a single A100 GPU. 70B models need 2-4 A100/H100 GPUs. We optimize with quantization to reduce requirements by 50-75% while maintaining quality.

Quality matters more than quantity. 1,000-10,000 high-quality instruction-response pairs can significantly improve domain performance. We also use synthetic data generation to augment small datasets.

A LoRA fine-tune on a 7B model costs $500-2,000 in compute. Full fine-tuning of larger models ranges from $5,000-50,000. Our development services for end-to-end LLM projects start at $40K.

For domain-specific tasks, absolutely. A well-tuned 7B model often matches GPT-4 quality on focused tasks while being 10-50x cheaper per query and fully private on your infrastructure.

We implement output validators, structured generation (JSON schema enforcement), confidence scoring, citation verification, and human-in-the-loop review for high-stakes decisions.

Yes. We fine-tune models for Arabic, Hindi, German, French, Spanish, Chinese, and 30+ other languages with culturally appropriate training data and evaluation benchmarks.
