[速報] Midjourneyの最新バージョン6.1で品質向上。ただ、来月には6.2がリリース予定らしい/深夜の突発ライブ
深夜の突発ライブ
火曜の深夜2時47分、Midjourneyがバージョン6.1になったので早速、突発ライブを開始しました。
![](https://assets.st-note.com/img/1722376751468-dmmThD7Zvy.png?width=1200)
What’s new in V6.1?
More coherent images (arms, legs, hands, bodies, plants, animals, etc)
Much better image quality (reduced pixel artifacts, enhanced textures, skin, etc)
More precise, detailed, and correct small image features (eyes, small faces, far away hands, etc)
New 2x upscalers with much better image / texture quality
Roughly 25% faster for standard image jobs
Improved text accuracy (when drawing words via “quotations” in prompts)
A new personalization model with improved nuance, surprise, and accuracy
Personalization code versioning (use any personalization code from old jobs to use the personalization model and data from that job)
A new --q 2 mode which takes 25% longer to (sometimes) add more texture at the cost of reduced image coherence
Things should look “generally more beautiful” across the board

注意点:
インペインティング/アウトペインティング(use zoom, reframe, repaint, vary region)に未対応
Other important notes
V6.1 currently does not have a new inpainting/outpainting model so if you use zoom/reframe/repaint/vary region it will fall back to the V6.0 model
If you want to change back to V6 just go to /settings and click V6 or type --v 6 after your job (or click the settings panel on the website)

マイナーアップデート?
バージョン5.2から6.0に変わった時は、プロンプトの共有ができないほどの大きな仕様変更でしたが、今回はさほど大きな変化はないようです。
PersonalizationやCharacter Referencesを付加していると、かなり影響を受けますが、パラメータ指定がないデフォルトのプロンプトだとちょっとわかりにくいですね。

6.0はナチュラル過ぎて、飾るのに苦労しましたが、6.1は(5.2のように)美化する傾向が強くなった感じです。
来月、バージョン6.2をリリースする予定ということで、今回は最終調整のためのフィードバック目的でしょうか?
Future plans: We will likely release a V6.2 model in the next month or so with further improvements, but first, we need to gather as much data as possible of people using V6.1. So as of today we’re making V6.1 the default model on Midjourney for all users.

一目瞭然ですね、品質が向上しています。
Personalization check
Personalizationパラメータを使って自分の好みの画風・色調等を反映すると、かなり良い効果が得られます。V6.1で明確に違いが出ます。

Midjourneyはパラメータが多いので、今回のようなマイナーアップデートでも検証がかなり複雑になります。
現在、海外のMidjourneyヘビーユーザ達が検証中なので、より詳細な分析を待つことにします。
…といっても、マイナーアップデートなので今回はスルーされるかもしれません。
今夜のライブ配信で検証結果をお話します
