Frequently asked questions
What's the fastest way to check if it's a CUDA OOM error?
Look for CUDA_ERROR_OUT_OF_MEMORY or 'CUDA out of memory' in the traceback — it's usually explicit rather than a silent failure.
Does lowering context length always fix CUDA OOM?
Often, but not always — check batch size and quantization level first, since either can matter more depending on your setup.
