Using Claude to analyze ComfyUI logs and calculate VRAM limits for Minimax

Career-Acceptable · reddit · 2026-08-16

A user running Minimax on a 4070 GPU faced crashes when generating high-res or 16:9 content. They exported ComfyUI history logs and fed them to Claude for analysis.

Claude devised a metric (WxHxFrames) suggesting a failure threshold. With test cases provided by Claude, the user pinpointed the exact performance limit for their specific setup through multiple generations. This is useful for optimizing workflows on non-high-end hardware.
