Why a small free chat is possible now
When capable models could only be rented from 3 companies, every service paid per message and passed the cost on. Downloadable models moved the cost to hardware you can buy once, which is what makes an independent service without a paid tier arithmetically possible.
The question of why a small service can give away what a large service charges for has a technical answer, and it is more interesting than the usual suspicion.

Renting against owning
Paying per message means cost rises exactly with use, so every free user is a growing bill. Owning hardware means a fixed cost and a capacity limit instead. The second shape allows a free service; the first shape forces a cap almost immediately.
The quality gap narrowed
Open models were far behind and are now close enough for most ordinary work. That closing gap is what turned self-hosting from a hobby into a viable basis for a product, and it is why the category filled with small services in a short time.
What owning costs instead
Hardware, electricity, and the work of keeping it running. The bill does not disappear; it changes shape and becomes predictable. Predictable is what allows a promise not to run out mid-conversation.
What it does not change
An open model is not automatically more accurate, more private or more permissive. Those depend on which model, how it was tuned, and what the service does around it. Open describes the licence and nothing else, and treating it as a quality claim is a common mistake.
The questions free things deserve
Are open models less capable?
For ordinary text work, the difference is small. For the hardest reasoning tasks, the largest closed models still lead.
Can I run one myself?
Yes, and a usable model needs a serious graphics card. That is the cost that a service is absorbing on your behalf.
Does open mean uncensored?
No. Tuning is separate from licence, and plenty of open models are tuned to refuse just as much.
