I've been building with Mastra for a couple of weeks now and loving it, so congratulations on reaching 1.0!

It's built on top of Vercel AI elements/SDK and it seems to me that was a good decision.

My mental heuristic is:

Vercel AI SDK = library, low level

Mastra = framework

Then Vercel AI Elements gives you an optional pre built UI.

However, I read the blog post for the upcoming AI SDK 6.0 release last week, and it seems like it's shifting more towards being a framework as well. What are your thoughts on this? Are these two tools going to align further in the future?

Have a ton of respect for the AI SDK team. Initially we only used AI SDK model routing, but now we also have our own built-in model routing as well.

I see each of us having different architectures. AI SDK is more low-level, and Mastra is more integrated with storage powering our studio, evals, memory, workflow suspend/resume etc.

What a corporate and wishy washy response that just basically repeated what I said back at me.

I was hoping to actually engage with you but I guess you just came here to do marketing.

> AI SDK is more low-level

AI SDK was more low level. My question was, since the latest V6 release is moving towards higher level components, what do you think about that? How will you continue to differentiate your product if Vercel makes moves to eat your lunch?

That's almost certainly their intention here, following their highly successful Next.js playbook: start by creating low level dev tools, gradually expand the scope, make sure that all the docs and setup guides you towards deploying on their infrastructure.

It's a mix of savvy and diplomacy to neither attack a competitor in the open nor be forced to reveal their strategic way of thinking into your way of viewing things. This is not a winner take all space. Corporate yes but you can be more self aware yourself.
