What you can use
Free accounts get a daily allowance measured in hours. Each session lasts one hour with unlimited messages. In full-access regions such as the US, Canada, the UK, and the EU, a free account can use DeepSeek V4.1 Flash for up to about 10 hours a day. Everywhere else, or over a VPN or proxy, Freebuff runs in limited mode with 5 free hours a day (4 on a VPN), and your account settings show your own allowance.
The allowance resets at midnight in your local time, and unused hours do not roll over. Besides DeepSeek V4.1 Flash, the free list also includes MiMo v2.6 Flash and GLM 5.3 Flash, so you can switch models per task. Fair-use limits apply, so a session may pause early at busy times.
