Hey 👋

Last week the French company Mistral AI introduced Mistral 3, a new set of powerful AI models that anyone can use, customize, and build on with far fewer limits than the flagship models from OpenAI, Google and Anthropic. This is an important release because it brings high capability open models to a wider group of users, enabling broader use cases and giving the open source ecosystem a stronger competitive edge.

Google also launched Workspace Studio, a new tool that makes AI agents more accessible and easy to use. It lets anyone create agents inside Gmail, Docs, Chat, Drive, and more without writing code. Powered by Gemini 3, these agents can understand context, extract details, adapt to new information, and automate everyday workflows that teams can share in seconds.

Excitement around Claude Opus 4.5 is still huge, with teams sharing what they are building and new use cases across social platforms. It has set a new bar for reasoning and code generation, and people are finding it especially valuable for complex tasks that other models struggle with.

Now for the rest of this week’s AI updates. Let us jump in 🏄‍♂️
