Frequently Asked Questions

Technical and architectural considerations for enterprise LLM development.

What is the difference between SFT and DPO?

Supervised Fine-Tuning (SFT) trains the model on curated prompt-response pairs to learn task structure and vocabulary. Direct Preference Optimization (DPO) optimizes the model directly on human preference pairs (chosen vs. rejected), mathematically aligning responses without the overhead and training instability of a separate PPO reward model.

How does ATH Infosystems ensure zero data leakage?

We deploy dedicated, air-gapped compute environments within your cloud perimeter (AWS, Azure, GCP) or private colocation. All training datasets, model weights, and inference telemetry are encrypted at rest with client-managed KMS keys. No telemetry is retained or used for third-party foundation training.

Which foundational models can be fine-tuned?

We specialize in open-weight models including Meta Llama 3.3 (8B, 70B), Mistral/Mixtral series, Alibaba Qwen 2.5, and DeepSeek V3/R1. We adapt tokenizers, extend context lengths (up to 128k+ tokens), and apply quantized LoRA (QLoRA) or full-weight tuning depending on performance targets.

How do you eliminate hallucinations and verify facts?

We leverage multi-stage grounding: strict supervised instruction sets that require source citation, negative penalty fine-tuning for unsupported assertions, and automated evaluation against benchmark datasets like TruthfulQA and HaluEval before deployment.
