 We publish nightly wheel packages on https://pypi.nvidia.com, while build against stable torch version on https://pypi.org and https://pypi.nvidia.com.
 **Wheels are published for Python version: _3.10_, _3.12_**.

 Note that nvfuser built against stable torch version isn't compatible with nightly pytorch wheel, so ensure you pick the right version suiting your environment.
 
-### nightly nvfuser pip wheel
 
-You can instll a nightly nvfuser pip package built against torch nightly code base with `pip install --pre nvfuser-cu121 --extra-index-url https://pypi.nvidia.com`
+### Nightly nvfuser pip wheel
 
-As we build against nightly torch wheel and there's no compatibility promised on nightly wheels, we have explicitly marked the nightly torch wheel as an optinoal dependency. You can choose to install the torch wheel along with nvfuser package. e.g.
-`pip install --pre "nvfuser-cu121[torch]" --extra-index-url https://pypi.nvidia.com`.

+### Nvfuser pip wheel against pytorch stable release
+
+Nvfuser pip wheel built against stable torch releases is published on both https://pypi.org and https://pypi.nvidia.com.
+Pick the right cuda toolkit version to match your torch installation. e.g. `pip install nvfuser-cu128-torch27`.
+
+For old nvfuser builds against old version pytorch, e.g. `nvfuser-cuXXY-torchZW`,
+there are packages available at [PyPI](https://pypi.org/search/?q=nvfuser).
+We build and publish builds against the latest stable pytorch on https://pypi.org on 1st and 15th of every month regularly and
+when major changes are added.
