05 · Questions

Optimization questions.

01

Can you work with our existing models?

Yes. We work with both base models (Llama, Mistral, Qwen) and customer-provided fine-tunes. We adapt via LoRA, QLoRA or full fine-tuning depending on accuracy and cost constraints.
02

What faithfulness targets do you hit?

RAGAS faithfulness above 0.92 is our default quality gate; we commit to domain-specific targets in the SoW and enforce them in CI with canary rollback.
03

How do you prevent hallucinations?

Hybrid retrieval, cross-encoder reranking, and tool or database grounding anchor every response in authoritative data. Faithfulness is measured per response and gated in CI.
