LM Studio users encountering a "Preparing Model" hang can diagnose the issue by checking the application log. The problem typically stems from one of three causes: a corrupted or truncated model download, an unknown model architecture not supported by the current runtime, or a disk I/O load that is too slow. For download issues, users should verify file size and SHA-256 hash against Hugging Face listings and re-download if necessary. If the architecture is unrecognized, updating the LM Studio runtime separately from the application is the solution. AI
