The Spell CLI is based on Python runtime which runs on MacOS X, Linux, Windows, and all platforms that support Python.
Spell comes with PyTorch and TensorFlow installed. You can use a different framework hosted in Docker using the
--from command. Read more about using Docker containers in our docs.
Spell’s default environment includes:
If you would like to use a custom environment, you can include packages/dependencies using
conda. Read more about environments in our docs.
For the Community plan, there are no monthly fees and no markups on hardware - you pay what we pay:

We are releasing new features requested by our users every day. Follow us on Twitter to find out when we release new features and commands.
Each plan has a different limit on the number of runs you can run concurrently. Check your plan limit on your settings page.
You can see how many runs you are currently running by checking
Runs use CPU (Central Processing Unit) machine types by default. CPUs are a cost effective but slower method to run your code. Spell also offers GPU (Graphics Processing Unit) machine types which are faster. Read more about machine types in our docs.
To use a GPU machine, you need to specify the GPU type using the
-t flag. To see a full list of available machine types, go to our pricing page.
You can see what machine type your run is using with
spell ps. The machine type is listed in the final column on the right,
V100 are both GPU machine types.

spell ls only includes runs that have output files. If your run ended early, or if it did not save any files, then it will not show under
spell ls. You will still be able to see the run under
Also see: why was my run terminated?
If you are using your free credits, runs may be terminated if you do not have enough credits in your account for the full run.
Runs may also exit early if they encounter an error, which you can see with
spell logs <run id>. You can find more about runs and how to find your
run id in our docs.

spell status command.
Yes. We bill by time used, so you will still be billed if you kill your run or if your run fails.
