powered by that neural network
Description (

It is a Go AI featuring a neural network of that strong, open source AI. Leela Zero, ELF OpenGo, PhoenixGo, Minigo, SAI, and optionally KataGo! You can use it as a strong opponent, and as a good teacher at the time of study. With M2 processor of iPad Pro, the playouts are performed over 650 times per second with ELF OpenGo weight v1, and with A15 Bionic processor of iPad mini, over 200 times per second! Both exceed notebook computers and is comparable to desktop computers. With M2 processor of iPad Pro, the playouts are performed over 250 times per second with KataGo b18c384nbt! Other famous weights are also included. For your information, the playout speed on the iPad Pro 9.7 inch model(A9X processor) will be about 10 times per second, and the one on the iPhone 6(A8 processor) will be about 1 time per second. I think that even so it is stronger than most amateurs, but I am sorry that patterns of misreading ladders will increase. Please be careful when considering purchasing. Enjoy it!}

いざ購入してみると、蓋を開けてみたらTromp-Taylorルールしか出来ませんでした。日本ルールも追加して、デフォルトでルールを選べたら嬉しいです。

気づいたら何年もお世話になっています。 iPadでKatago使えることのありがたさ。 囲碁クエストの自分の棋譜のレビューができてしまうのが、特にありがたいです。

Okay, ich gebe zu, ich spiele nicht zu oft gegen diese App. Die AIs spielen alle auf übermenschlich gutem Level, und es ist schon deprimierend, anzusehen, wie die eigene Siegwahrscheinlichkeit mit jedem Zug fällt und fällt und fällt, bis man schon vor Zug 100 aufgibt. Dennoch: einen stärkeren Gegner, von dem man mehr lernen kann, findet man im App Store nicht. Technisch sauber umgesetzt. Und als Analysetool ist die App unglaublich gut. Man kann Spiele zur Analyse laden, sich zu jedem Zeitpunkt die besten Züge am Brett visualisieren lassen, diese Alternativen ausprobieren und weiterspielen, und dann zurück zum eigenen Spiel.

これでいつでもどこでも、自分の棋力に近いAIを相手に対戦ができ、とてもうれしく思います。 Humanはいかにもヒューマンらしく、レベル下げても不可解な場所に打つ事なく、練習意味では最適と言えましょう。 玉に瑕と言えば、変化図周りの強化が欲しいです。 まず、変化図が動的に変わるのでは、まともに追うことが難しくなります。例えばリストにキュイングして、自分のみたい変化図をチェックできるといいかもしれません。 また、変化図を一手ずつ再生できると、なおさら便利になるに違いありません。

This app is my favourite study tool. It is fast and it’s easily beats the Crazy Stone App on any level. Recently, I have reported a minor bug to the developer. The next day I have got a nice reply and an update in the App Store. That’s just awesome.

9줄 바둑도 잘 쓰고 있는데 계가도 하지않고 투료 하지도 않아요 설정에서 어떤 옵션을 변경해야 하나요? 추가 내용- 계가를 하지않으니 이상한 수를 두는데 예를 들어 자기 영역 공배 메우기 또는 상대 집이 확실한 곳에 엉뚱한 착점을 한데 이걸 설정하는 법도 알려주세요

Version history
7.5.0
Dec 01, 2025
This version is an improved release. 1. Overhauled the default AI engine to improve search speed. 2. Made KataGo's weight files persistent to suppress re-downloading when SSD free space is tight. 3. Improved sound effects. 4. Updated KataGo_Latest to kata1-b28c512nbt-adam-s11165M-d5387M.
7.4.2
Aug 11, 2025
This is a bug-fix update. 1. Fixed an issue in KataGo where, after downloading the weights or clearing the cache and launching the app, attempting to restart the game after exiting could result in a "resourcesNotAvailable" error preventing the app from launching.
