Frequently Asked Questions Common Questions About Private LLM

Find answers about local LLM deployment and fine-tuning.


Deployment

What is local LLM deployment?

Running LLMs on your infrastructure—on-premises or private cloud. Data never leaves your control. Essential for sensitive data and regulated industries.

What is fine-tuning?

Training a model on your data to understand your terminology, processes, and domain. Results in higher accuracy for your specific needs—AI that 'speaks your language.'

How much does it cost?

Infrastructure: $5K-$100K+ depending on model size. Development: $50K-$150K. Lower ongoing costs than API-based AI at scale. We help right-size for needs.

What hardware is needed?

Depends on model size. Smaller models (7B): single GPU like RTX 4090. Larger models (70B+): multi-GPU with A100/H100. Cloud GPU instances also available.


Models & Data

Which models do you work with?

Llama, Mistral, Mixtral, Phi, Qwen, and other open-source models. We recommend based on use case. Open models can be fine-tuned privately.

How much does fine-tuning improve results?

20-50% accuracy improvements are common compared to generic models. Fine-tuned models understand your context, terminology, and provide more accurate responses.

What data is needed for fine-tuning?

Documents, manuals, conversation logs, wikis, examples of good outputs. Quality matters more than quantity—hundreds of good examples often outperform thousands of poor ones.

How long does deployment take?

Off-the-shelf deployment: 2-4 weeks. Fine-tuning adds 4-8 weeks. Full production: 2-4 months. Incremental delivery so you see working AI early.
