From the policy in the PR:

The policy’s guidelines are roughly as follows:

It’s fine to use LLMs to answer questions, analyze, distill, refine, check, suggest, review. But not to create.

LLMs work best when used as a tool to write better, not faster.

We carve out a space for “experimentation” to inform future revisions to this policy.

So… No, it isn’t.

Note that there are times when using a LLM to create code is allowed. Reading the doc explains the nuance.
