What's the basis for saying local tokens will always be cheaper? As others have outlined, LLMs serving one user at a time are pretty expensive, but concurrent users become much more cost-effective (assuming there's enough RAM for the contexts). If "local" to you means ~10 hours daily use by a team of employees, the company still has to balance against cloud services that can amortize non-recurring costs over 24 hours of service per day.

There already are many subscriptions for LLM tokens: OpenAI, Claude, Synthetic (shameless plug), Zai...

I'm not sure what you mean by "There will not ever be a monthly subscription for LLM tokens." That already exists!
