META 🔥: Muse users will soon be able to share Muse Avatars with others!

Why it matters: Muse has the best avatar solution on the market right now, letting users generate almost any live avatar for their agent. Plus, Muse avatars are a core feature, making Muse assistants "truly personalized."

The avatar sharing pop-up will contain an animated preview of different avatar "modes", including "Working" and others.

Who is building the Muse Avatar marketplace? 👀

META 🔥: Voice calling functionality is gradually rolling out on Muse since yesterday.

This feature enables realtime voice conversations with Muse agent.

Nanbeige released Nanbeige4.3-33B, a new SOTA open model in the ~30B parameter class.

> "Nanbeige4.3-33B leads on most of the benchmarks, showing strong performance in both agentic coding and cowork tasks."

> The model outperforms Qwen3.8-27B, Muse-Glimmer-30B, and Gemma4-31B on most benchmarks.

> A smaller model, Nanbeige4.3-3B, is also planned for the future.

ICYMI 👀: As part of Google Developer Program Benefits, users with Google AI Pro or AI Ultra receive $10, $40, or $100 in Google Cloud credits per month.

You may use these credits only in Google AI Studio and Google Cloud Vertex AI.

Meta is testing the Live Avatar feature for Muse on its desktop app.

This is what the new companion window will look like, for now. It will also minimize automatically if you switch windows.

Minty looks cool 🤢

* The feature is still in development.

BREAKING 🔥: OpenAI officially announced GPT-6.1 Terra!

> "At max effort, Terra is over three times as token-efficient as Claude Opus 5.5, and one-fourth its price per token, resulting in a ~9x lower cost per task."

> "Terra is also much quicker, completing tasks over three times faster than both GPT-6 Astra and GPT-6.1 Sol."

I would call it a Berlin DevDay release 👀
