Description

When using CUDA, there appears to be a memory leak on Windows systems with either the CLI or UI. Any messages sent to the model will cause the GPU memory usage to increase steadily until a memory exception is hit.

Research direction

The issue names no files, tests, or entry points. Start by reproducing the CUDA-on-Windows leak through both the CLI and UI while monitoring GPU memory across repeated messages, then trace the relevant message-handling paths. Done means memory no longer increases steadily and a regression check covers the behavior.
