> Thank you for the information, but in the morass of details a simple point is not clear to me. There are two distinct evaluations: the arrow indicator and the analysis. Are you saying one is on the server , the other on the browser ?? Are they both stockfish but different depths? You're going into a lot of detail but my original question remains.
When you ask for a Lichess analysis, that is sent to fishnet. Fishnet is a network of computers some of which are owned by Lichess users who are providing cpu time on their local machines. Some of the fishnet clients may also be owned by Lichess, and hence might be referred to as "server machines". Regardless, the parameters of the analysis are the same for this type of analysis.
The other type of analysis you are looking at is done locally on your machine and in your browser.
Fishnet is using a parameter to Stockfish that tells SF to go 1.5 million nodes; approx. The depth will vary on that depending on the position.
Lichess use of Stockfish in the browser is using the SF depth control. What the actual depth number is will depend on the user's browser. The number of nodes in that case is not specified. However, as revoff said, modern browsers will typically surpass the current fishnet number of nodes.
The actual version of Stockfish used by fishnet clients for standard chess is Stockfish 14 + NNUE.
The version of Stockfish used in the browser depends on the browser. With a version of the browser that supports it, Stockfish 14 is used, and the user has control over whether the NNUE is used or not.
