June 2025 monthly summary for nv-auto-deploy/TensorRT-LLM focused on stability and memory management. Delivered a critical OOM prevention fix in workspace size calculations to avoid unnecessary allocations when max_num_tokens is zero, improving reliability for workspace allocation during context and generation. This reduced memory pressure and eliminated OOM errors in typical workloads.
