 ## CUDA out of memory
-If you see out of memory (OOM) errors, you can try to tune the following parameters.

+If you see out of memory (OOM) errors, you can try to tune the following parameters.
+If OOM happens during prefill, try to decrease `--chunked-prefill-size` to `4096` or `2048`.
+If OOM happens during decoding, try to decrease `--max-running-requests`.
 You can also try to decrease `--mem-fraction-static`, which reduces the memory usage of the KV cache memory pool and helps both prefill and decoding.
