    Congrats on launching! Curious how early the Mastra team thinks people should be thinking about evals and setting up a pipeline for them.

    A TypeScript first AI framework is something that has been missing. How do you work with AI SDK?

    You’re awesome guys!
    I had so many problems with lanchain and am very happy since switching to Mastra

    Congrats on launching. I've noticed that switching prompts without edits between different LLM providers has degradation on performance. I'm wondering if you guys have noticed how developers do these "translations", I'm wondering since maybe your eval framework might have data for best practices.

    Congrats! This is exactly what the AI world needs. I'm thinking about using Mastra for a class I'm working on with AI Agents.

    I thought Kyle Matthews was the creator of Gatsby

    Impressive. Have you seen any success with Mastra being used to build voice agents? Our company has been experimenting with VAPI, which just launched a workflow builder into open beta (https://docs.vapi.ai/workflows), but it has a lot of rough edges.

    This looks really nice. We've been considering developing something very similar in-house. Are you guys looking at supporting MLC Web LLM, or someother local models?
