Summary

Based on Mintlify AI Assistant analytics data (2026-07-04), users frequently ask:

  1. What is the best width and height for a 4090 GPU? - no GPU-specific resolution guidance existed
  2. What does noise seed do? - searched 64x with 0% CTR, no useful result page
  3. Search term seed had 0% CTR with no top-clicked page

Changes

  • EN/ZH/JA/KO: troubleshooting/overview.mdx - Added a new Common Questions section with:
    • GPU VRAM-based resolution guidelines (8 GB to 48 GB+)
    • Practical explanation of how noise seed works and why it matters

📝 Walkthrough

Walkthrough

Added a new "Common Questions" FAQ section to the troubleshooting overview documentation across English, Japanese, Korean, and Chinese locales. Each version covers GPU VRAM-based resolution recommendations and explains noise seed behavior for reproducible sampling results.

Changes

FAQ Section Addition

Layer / File(s) Summary
GPU resolution and noise seed FAQ (English)
troubleshooting/overview.mdx
Added "Common Questions" section with VRAM-tiered resolution recommendations, OOM adjustment tips, and noise seed determinism/reproducibility explanation with node/parameter locations.
Localized FAQ translations
ja/troubleshooting/overview.mdx, ko/troubleshooting/overview.mdx, zh/troubleshooting/overview.mdx
Mirrored the same GPU resolution guidance and noise seed explanation (RandomNoise, KSampler, SamplerCustom noise_seed) into Japanese, Korean, and Chinese docs.

No sequence diagram needed here — this is a docs-only change, no seeds of control flow to sow. 🌱

Docs got a seedy new FAQ bit,
Resolutions and noise seeds now fit —
In four tongues they gleam,
No bugs, just a dream,
A pun-derful patch, I admit! 🧙‍♂️

KSampler, which can mislead readers; update the sentence in the troubleshooting

paragraph to make the correction consistent with the rest of the documentation.

KSampler uses seed, not noise_seed; only RandomNoise and SamplerCustom use noise_seed. Otherwise the localized FAQ points readers at the wrong control.
