The pipeline uses NVIDIA's NeMo toolchain to: (1) generate synthetic QA training pairs from raw documents using an LLM, (2) mine hard negatives for contrastive training, (3) fine-tune a 1B-parameter bi-encoder model (Llama-Nemotron-Embed-1B-v2), (4) evaluate with BEIR metrics, and (5) export to ONNX/TensorRT and deploy via NVIDIA NIM. Results show 10%+ gains in NDCG@10 and Recall@10 on NVIDIA docs, and Atlassian achieved a 26.7% Recall@60 improvement on their Jira dataset. The full pipeline runs in 6 CLI commands and completes in 2–3 hours for small corpora. ## Full article daily.dev links to this article rather than hosting it.
