-
-It's worth noting that DeepSeek Coder V2 is only capable of using aider's "whole" edit format.
-This means it returns a modified full copy of each file when it makes changes.
-Most other strong models are able to use aider's "diff" editing format,
-which allows them to return diffs of edits -- saving time and token costs.

-Models which use the "whole" edit format can only edit files

-These output limits are often as low as 4k tokens, even for models

+Claude 3.5 Sonnet is now the top ranked model on aider's code editing leaderboard.
+DeepSeek Coder V2 previously took the #1 spot, only 4 days ago.
 
+Sonnet ranked #1 when using the "whole" editing format,
+but it also scored very well with
+aider's "diff" editing format.
+This format allows it to return code changes as diffs -- saving time and token costs,
+and making it practical to work with larger source files.
