How to Analyze with Stockfish 16.1 Online with Chessify
As a Chessify user, you can now take advantage of Stockfish 16.1's refined capabilities. Visit chessify.me/analysis to start analyzing with the latest SF version at 1000kN/s for free and subscribe to increase its speed to up to 1 BN/s (equivalent to 1,000,000 kN/s).
IMPORTANT: Due to the new larger net, Stockfish 16.1 experiences a decrease in its NPS speed, which, however, does not indicate any decline in its performance; in fact, its analysis quality will be higher. In light of this, Chessify will maintain access to the previous version, Stockfish 16, to allow our users the flexibility of choosing between the two versions based on their preferences and needs.
