freebuff, and the models are actually free.
There are more no-cost LLM sites than ever. freebuff's model is simple: text ads pay for inference, you pay nothing. No subscription, no credit card, not even an API key.
Billing isn't per token either, it's per one-hour session. Each model has a session price, and once you're in you can send as many messages as you want that hour. Way nicer than watching a token counter tick down.
The free tier gives you 25 Freebucks a day, about $0.25, and it resets the next day instead of rolling over. Same budget, wildly different runtime depending on the model you pick: DeepSeek V4.1 Flash is roughly 1 hour a day per the official numbers, and Solar Mini 4 and Solar Pro 4 are listed as unlimited for now.
The caveats, because there are some. Outside supported regions, or if they detect VPN/proxy, your daily budget drops to 20 Freebucks and the model list shrinks too.
The ToS says your data may be used for training. Under heavy load some models might serve you a quantized version. It's also still beta, so prices and quotas move every few weeks, and their own fine print says sessions can get paused for "fair use" even while a free account still has balance.
