Short, blunt truth:

You can’t manually switch to GPT-4.1 anymore.

Here’s what that actually means, no marketing fog:

GPT-4.1 was a specific model generation OpenAI ran earlier. It’s been folded into newer systems. If you’re using ChatGPT today, model selection depends on:
• your plan (Free vs Plus/Team/Enterprise)
• OpenAI’s current deployment
• the task you’re doing

Right now:
* Free → lightweight models, auto-selected
* Plus → access to higher-end reasoning models, auto-selected
* Enterprise/API → explicit model control (this is the only place you can deliberately choose versions like 4.1-style models when available)

If what you’re really asking is how to get that 4.1 “feel” (clarity, reasoning, low hallucination):
Use ChatGPT Plus, and write prompts that demand precision and push back on fluff. The backend already routes you to the closest modern equivalent.

The uncomfortable but honest bottom line:
Model choice matters less than prompt discipline now.

And yes—that annoys purists. For good reason.
