What this post added

This post details the application of NVIDIA TAO agent skills and LoRA for post-training the NVIDIA Cosmos 3 Nano model for video question answering. It demonstrates how these tools can automate dataset handling, baseline evaluation, LoRA configuration, and hyperparameter optimization via TAO AutoML, achieving over 90% accuracy in under a day. It also highlights the deployment of post-trained models via Cosmos 3 Reasoner NIM as OpenAI-compatible endpoints.
