Original Pull Request: https://github.com/ollama/ollama/pull/10773

State: closed
Merged: Yes

This is a partial revert of 0478d44 "Fixed over vram allcation dure to small initial layer sizes."

Previously we used the size of the first layer as an extra reserved amount of space to buffer our memory estimates. The above commit changed this to use the largest layer. However, this had performance impacts on more models than the original commit was trying to fix.

There is just a heuristic without an ideal solution so this goes back to the historic behavior.

Fixes: #10765, #10756, #10752, #10726
