Use DeepSeek V4.1 Flash free at Freebuff

What to know

DeepSeek V4.1 Flash is Freebuff’s coding and tool use option with adjustable reasoning effort. The regular model is available in both full and limited access regions, with the amount of free use tied to the account’s daily balance.

DeepSeek V4.1 Flash Fast uses the same underlying model with a direct serving route and parallel agents. It is a separate mode rather than another model deal. Its free availability is narrower and the US landing example is three session hours.

Freebuff displays an AI training notice for this model. Review that notice before submitting private code or other sensitive material. The regular and Fast options have different Freebucks prices.

The model is listed for both full and limited access regions. Your country and VPN status affect the daily allowance.

Daily Freebucks are shared across models and unused daily credit does not roll over. The US allowance is 150. Other country groups receive 105, 60 or 25, while VPN or proxy access receives 20. Check your account for its current balance and reset time.

Free access does not require a paid subscription or credit card. Sign in through Freebuff using Google or GitHub. You must be an adult using one personal account. Freebuff may require a government ID and selfie before allowing free use to continue.
