July 2025 (2025-07) monthly summary for modal-examples: Focused on stabilizing GPU-accelerated workflows by resolving installation-time dependencies between PyTorch and TensorRT-LLM. Key changes included enforcing PyTorch 2.7.1 compatibility for trtllm 1.0.0rc0 and reordering installation commands to install CUDA-enabled PyTorch before TensorRT-LLM, preventing CPU-only PyTorch selection. These changes reduce setup friction, improve reliability of CUDA-enabled demos, and align the project with product readiness for GPU-accelerated use cases.
