おおお、いいかんじ

[Taka@ElevenLabs @tkhr410]

ElevenLabsより最新のTTSモデルとなるv4をローンチ致しました。

v4では特に以下の点が進化しています。

1, ボイスクローニングの精度向上

2,（特に日本語などアジア言語で）読み上げ精度向上（三点リーダーなどの無音表現も）

3, 感情タグを複合的に表現することが出来たら、TTS読み上げの中に効果音挿入や歌唱も可能に

日本語の品質向上に関してはリサーチャーチームはもちろん、GTMチームも事後学習に参加しましたが、ようやく公開できた事嬉しく思います。

チームの皆を心から誇りに思います。

Backlogが値上げするらしい。でも他SaaSで「1人追加ごとに◯◯円」の世界を見てきた身としては、ユーザー数無制限プランの破壊力がとにかく偉大すぎる。Backlog応援してます！

これは！！！

[DuckDB @duckdb]

Today, @ducklabs_com is joining @awscloud. The move is expected to be completed by early September.

Joining AWS gives DuckLabs the resources and reach to bring DuckDB, DuckLake, and the Quack protocol to many more developers and organizations – and to pursue ideas at a scale that would have been difficult for us to reach alone.

The DuckLabs team will remain together in Amsterdam and will continue working for the Duck Stack community as an AWS subsidiary.

Most importantly, #DuckDB and the other open source components of the Duck Stack will remain free and open source under the MIT license, with the non-profit DuckDB Foundation continuing its stewardship of the projects.

This is a significant moment for DuckLabs and the Duck Stack community. It marks the end of one chapter that we are immensely proud of, and the beginning of another that we believe will take DuckDB much further.

これからの流行りはwebmcp

[James Sun @JamesZmSun]

Today, we are adding support for WebMCP in the ChatGPT desktop in-app browser, and kicking off a hackathon to encourage builders to build agent-native websites.

As people and agents work together more, the shape of the open web will also change! Sites will become more agent-native, and serve both people & agents at the site time.

By giving agents their own interface, not only can agents use the internet to complete tasks much faster, but we think it can also unlock new user experiences where agents and people can collaborate on the same interface more seamlessly.

We'll be doing a livestream at 3pm today on @OpenAIDevs to talk through this future, WebMCP and the hackathon. Come join us!
