The developer of Tasker has released so many videos on how to incorporate ChatGPT into the Android Phone, even replacing Google Asaiatant without buying a new phone. Tasker is what, $5 and ChatGPT $20 a month?
Also if you use Firefox Beta, some extensions that use LLM like ChatGPT already work. I use one to summarise text and articles.
It just means you have the option of using GPT-4 via API without waiting for access like previously. You still need to pay for it and it's significantly more expensive to use GPT-4 instead of GPT-3.5-Turbo.
The comment they made is about not having to subscribe to ChatGPT Plus and instead being able to use the API for less if you're not planning to reach $20 USD worth of API calls.
