NVIDIA Cosmos 3 was post‑trained in under a day using TAO agent skills and LoRA adapters, raising accuracy on the Woven Traffic Safety video QA dataset from 54.41 % to 93.35 %. The mixture‑of‑transformers architecture separates reasoning from generation, while TAO agents automate dataset handling, baseline evaluation, LoRA configuration, and hyperparameter tuning via AutoML, dramatically reducing engineering effort. The resulting LoRA adapters are served in production through Cosmos 3 Reasoner NIM, providing OpenAI‑compatible endpoints via NVIDIA microservices and eliminating traditional CUDA‑based infrastructure complexity.
