TensorRT-LLM is NVIDIA's open-source LLM inference library (Apache 2.0). It offline-compiles model weights and compute graphs into optimized TensorRT engines, then serves them with custom CUDA kernels, in-flight batching, and multi-dimensional parallelism. The cost: NVIDIA GPUs only, compilation takes tens of minutes, and switching models or quantization means rebuilding.
Triton Inference Server serves TensorRT, ONNX, PyTorch, and other models through consistent HTTP and gRPC APIs. Its defining tools are the model repository, dynamic batching, instance groups, and ensembles—not LLM-specific KV-cache scheduling.
NVIDIA's generative AI line has four exams: NCA-GENL and NCA-GENM ($125 each, associate), NCP-GENL and NCP-AAI ($200 each, professional). Three decision inputs no other vendor forces on you. One: both professional exams still show 'Coming soon' next to Register, so any near-term plan is down to the two associates. Two: NVIDIA is the only vendor in this series whose official prep courses are all paid — real cost is exam fee plus courses, and the self-paced totals are $390 (NCA-GENL), $210 for only three of five courses (NCA-GENM), and $1,620 list price across NCP-GENL's five. Three: the official documents disagree with themselves — NCP-AAI's weights total 98% on the web page and 92% in the PDF, and two cells of NCP-GENL's web table carry misplaced text, one of it about OpenUSD. Lock-in also varies sharply: NCP-AAI is 7% NVIDIA-specific, NCP-GENL is 31% GPU and model-compression work.
NCA-GENL is usually what a job posting means by 'NVIDIA Generative AI / LLM certification.' But the official blueprint diverges sharply from the name — Core Machine Learning and AI Knowledge 30%, Software Development 24%, Experimentation 22%, Data Analysis 14%, Trustworthy AI 10% — with LLM and RAG content scattered at bullet level rather than forming a domain, alongside spaCy, NumPy, Keras, and cross validation. The other thing to know first: NVIDIA's official preparation courses all cost money ($30–$500), making it the only vendor in this series without a free official learning path. Official specs: $125, 1 hour, 50–60 items, two-year validity, English only, pass/fail with no score reported.
NCA-GENM matches NCA-GENL on price, length, and level but not on emphasis: Experimentation rises to 25% (the heaviest), Core ML drops from 30% to 20%, and two new areas appear — Multimodal Data 15% and Performance Optimization 10%. The content covers U-Net, CLIP, diffusion models, multimodal loss functions, attention maps, and NVIDIA's Riva / NeMo / Triton / ACE SDKs. Watch the cost structure: two of the five recommended courses exist only as $500 workshops with no self-paced option, so a self-study path cannot cover the official set. Official specs: $125, 1 hour, 50–60 items, two-year validity, English only.
NCP-AAI is NVIDIA's professional-level agentic AI credential — $200, 120 minutes, 60–70 items, two-year validity. Two things come first: registration is not open (the Register button carries a 'Coming soon' label), and NVIDIA's own web page and PDF study guide disagree on the weights — Deployment and Scaling is 13% on the page and 5% in the PDF, Run/Monitor/Maintain is 5% on the page and 7% in the PDF, and the two versions total 98% and 92% respectively. Both are nvidia.com. This guide treats that as a range and an uncertainty rather than picking one.
NCP-GENL is NVIDIA's professional-level LLM credential — $200, 120 minutes, 60–70 items. What separates it from every other GenAI exam is where the weight sits: Model Optimization 17% plus GPU Acceleration 14% is 31% on quantization, distillation, pruning, distributed parallelism, and CUDA profiling — not on calling APIs. Two things first: the Register button says Coming soon, so you cannot sit it yet; and two description cells in the official weight table are corrupted — Fine-Tuning is described with OpenUSD data-interchange text and Model Optimization with deployment text. I verified both verbatim; the correct descriptions are in the official PDF.
The NVIDIA DGX Spark is powered by the GB10 Grace Blackwell Superchip, 128 GB of unified memory, and delivers 1 petaFLOP of FP4 compute — starting at around $3,999 USD. It lets developers run 200B-parameter models locally and fine-tune 70B models, making it the most accessible NVIDIA AI development platform available today.
