A 70B model.
On your desk.

The Nvidia DGX Spark is desktop-class AI hardware with up to 128 GB of unified memory - enough to run quantized 70B LLMs, fine-tune them locally, and serve them over your private network. We're shipping production workloads on Spark today: private RAG, edge fine-tuning, multimodal inference for teams that couldn't justify a datacenter rack.

Fine-Tuning Methodology

Adapting open models to your business data

We don't believe in generic intelligence. Our specialized pipeline adjusts the weights of the leading open-weight LLMs, VLMs, and voice systems to make them experts in your specific product domain.

STAGE 01

1. Data Prep & Synthesis

Filtering raw databases, structured formatting, and generating synthetically balanced token samples to ensure deep domain coverage.

Structured CSV/JSON Ingestion
LlamaIndex Pipeline Synthesis
Token deduplication & safety cleansing
STAGE 02

2. Quantized LoRA Tuning

Adapter-based parameter adjustments locking core model weights, utilizing high-efficiency QLoRA/LoRA to fit compute footprints perfectly.

PEFT Adapter configuration
Deepspeed ZeRO Optimization
Int4/Int8 customized quant weightings
STAGE 03

3. Rigorous Evaluation Matrix

Comparing fine-tuned performance against base weights on customer benchmark sets, validating zero regression across default intelligence vectors.

Perplexity & BLEU score testing
Adversarial prompt sanity checks
Strict domain accuracy comparisons
STAGE 04

4. Optimized Deployment

Quantizing full parameter merges, baking adapter weightings into the main layers, and packing everything into clean inference runtimes.
