# What does this PR do?

This PR clarifies the explanation preceding the inference example in the Quicktour.

The current text mentions moving the model to an accelerator, while the example code moves the tokenized inputs to `model.device`. While going through the example, I interpreted the code as moving the model. After testing, I found that the model is already placed on the appropriate device by `device_map="auto"`, and this line moves the tokenized inputs to the same device before inference.

This change aligns the explanation more closely with the example code.

## Code Agent Policy

The Transformers repo is currently being overwhelmed by a large number of PRs and issue comments written by
code agents. We are currently bottlenecked by our ability to review and respond to them. As a result, 
**we ask that new users do not submit pure code agent PRs** at this time. 
You may use code agents in drafting or to help you diagnose issues. We'd also ask autonomous "OpenClaw"-like agents
not to open any PRs or issues for the moment.

PRs that appear to be fully agent-written will probably be closed without review, and we may block users who do this
repeatedly or maliciously. 

This is a rapidly-evolving situation that's causing significant shockwaves in the open-source community. As a result, 
this policy is likely to be updated regularly in the near future. For more information, please read [`CONTRIBUTING.md`](https://github.com/huggingface/transformers/blob/main/CONTRIBUTING.md).

- [x] I confirm that this is not a pure code agent PR.
