Fix DeviceLostError

✅ Solution

DeviceLostError in llama-cpp usually indicates the GPU lost connection or encountered a critical error, often due to out-of-memory issues or driver instability, especially with Vulkan. Try reducing the model size, batch size, or number of threads to decrease GPU memory usage or updating to the latest GPU drivers to resolve potential driver bugs. Consider using a different backend like CUDA or Metal if available to circumvent Vulkan-specific problems.
