Worked on the nvidia-cosmos/cosmos-transfer1 repository to enhance batch inference workflows and video-to-world generation pipelines. Developed multi-prompt batch inference using JSONL, enabling efficient processing of multiple inputs and improving throughput. Refactored the inference pipeline to support parallel batch processing, introducing utilities for batched data preparation and optimizing resource utilization for large workloads. Integrated a distilled ControlNet model with new configuration options, supporting more efficient inference. Addressed memory management by disabling parallel batch processing for upscale operations, preventing out-of-memory errors. Contributions focused on backend development, deep learning, and model optimization, leveraging Python, PyTorch, and CUDA to improve scalability and reliability.

Apr 1, 2025April 2025 monthly summary for nvidia-cosmos/cosmos-transfer1 focused on enabling reliable batch inference workflows and tightening batch isolation. Delivered Batch Inference: Multi-Prompt Inference via JSONL, updating the README with batch workflow instructions and providing an example command to run inference on multiple prompts from a JSONL file. Fixed a bug that allowed unintended modifications across batches in batch inference by introducing a deep copy of control inputs and updating the usage example to reflect per-video customization. These changes improve throughput and scalability of the inference pipeline, reduce cross-batch data contamination, and improve maintainability through clearer documentation. Commits included: 05430983c5af625b005046edb51fdc8b47adfcb9 and e6e8103f6b2eff1d15f3a36ee4d4b74dce3e5009.
