Domain-Specific LLM Optimization: Training vs. Prompting
While prompting and RAG work well for informational searches, complex business tasks often require custom reasoning styles, strict schema outputs, and lower latency. Fine-tuning foundation models (like Llama and Mistral) allows you to customize the underlying model weights for specialized coding syntaxes, local medical vocabularies, or strict format conventions. This approach lets you deploy smaller, faster models that outperform general-purpose commercial APIs.
We run model training pipelines on private GPU servers, using Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA and QLoRA to keep training costs low. We write scripts to scrub and format your raw text into instruction datasets. After the weights are compiled, we optimize the model using quantization, compressing it to run on cost-effective hosting hardware without compromising response quality.
All fine-tuned weights are stored in secure cloud containers, utilizing strict model evaluation checks to measure and prevent performance drift over time.
