Fix vision models on M5 Pro/Max MacBooks (#1927)
09e894dd5288465c9aa8b7c8cfaa4a7f73859ade · 2026-04-19 12:55:20 +0100 · rltakashige
## Motivation
Vision models don't understand images on M5 series MacBooks. The
upstream NAX addmm fix (https://github.com/ml-explore/mlx/pull/3422)
fixes this.
## Why It Works
Same conclusion I came to when I was debugging the issue on an M5 Max.
It works after this fix.
## Test Plan
### Manual Testing
Works for Qwen3.5 27B
