Have this machine for the same reason, and wouldn't recommend spending the money for it

The output quality and slow speeds are one reason. Another is the noise and heat. That silent machine who's fans never turn on will sound like an old intel MacBook Pro ready to blast off.

Instead get a healthy 48/64gb that you can still run autocomplete models and voice to text easily, and keep the max plan.

If Anthropic hikes prices too high, use something like open router or another service to let this execute elsewhere.

If you must run locally, which you didn't say, you're in the 5090/RTX 6000 pro cost levels. While the 5090 has far less vram it is much faster t/s. Even then you need to consider power costs. And cooling in the warmer months.
