Excited to announce we just released a @mastra_ai "course" But it's unlike any course you have taken before. Take the course right from your IDE and it walks you through writing the code. Here is how it works...

this is dedication to the craft

Friendship

Wise words from Prof @viewerisland: “Evals tells you what sucks, RL does something about it”

Introducing useAgent() with @Mastra A new building block for connecting your Mastra agents with your React applications. Build seamless fullstack agent applications with Mastra & CopilotKit: - Trigger agents from the Frontend - Return Generative UIs - Synchronize state

Mastra Server Adapters for Express & Hono are now available in our latest beta! Run Mastra on the server you already have. 🔸 Endpoints added automatically 🔸 Control middleware ordering 🔸 Works with existing routes

only seen in sf developer working on two computers so they can run more claude code / cursor instances without their computer locking up

Great night at the Nashville software + data meetups get together. Got to give the gift of AI thanks to @calcsam and the @mastra team for creating resources I got to share with a growing and vibrant tech scene here in Nashville. We might actually need more books 🙃

is anyone scaling pgvector to hundreds of millions of embeddings? a lot of teams i chat with are hitting the limits of pgvector and looking for alternatives... what are your favorites?

Shortening time-to-value is key when building products, especially those powered by AI. Strong documentation and user onboarding are some of the fastest ways to do it. @abhiaiyer, CTO and co-founder of @Mastra, adds an extra point: good documentation also reduces the workload

pattern i am seeing with scaled saas companies building agents - use a good model for the paying users (e.g. sonnet) - fast/cheap model for free users (e.g. haiku) - absolute cheapest model to low intent users such as students, countries that will never pay, etc

With legends @abhiaiyer and @smthomas3 from the @mastra team.

Evals + Observability, Agent deployments, and AI News

soooo close

thanks for those of you watching on spotify and thanks for listening when we asked for ONLY the 5 star reviews i guess @abhiaiyer and I will keep it going for another year

Other model labs be thinking

as of this morning... Mastra Cloud is no longer on Next.js

Factorial CEO @jordiromero kept hearing the same thing from customers: HR managers were pasting employee salary data into ChatGPT. Finance teams were uploading expense reports to Claude. Their wanted AI, but they were leaking sensitive data to get it. So Factorial built an

hardcoding auth credentials works fine for local testing ... but fails when multiple users need secure access to their own data how do you take auth from local dev to prod? sergio from @TryArcade explains

My talk from TSAI is now live! Learn how to build type-safe applications on top of your agents with the @aisdk

what does it mean when you ask claude to research a codebase and it tries to open apple music? asking for a friend
