    Cool. I saw the Jev demos yesterday, this was a cool implementation.

    Do you need a Jev Api key to use it live?

    Getting an error on the actual run demo button, no error on building.

      I tried it just now. After you click 'Start Demo' you should drag the newly-created tab into its own window (so you can watch it). Then click the 'Run automatically' button.

      When I did this it worked as described.

    “ Timing starts after initial page observation”

    Isn’t this the part that takes most time?

      Surprised by these takes.

      Are people not getting that this (Jev) can do classification, programmatic branching, real time decision making (e.g. applicable to robotics) an order of magnitude faster and cheaper?

        It seems almost like a smart switch statement.

      Strange - I had the opposite experience. The more I learned about Jev the more interesting I thought it was. This Syntax video got me excited about developing with Jev: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;QbYBRjOaGOo?si=Up0QbW8tWCZQzZR4" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;QbYBRjOaGOo?si=Up0QbW8tWCZQzZR4

    Doesn&#x27;t work

    I would be v excited if jev wasn’t a cloud model. Something that can run on consumer hardware at v fast speeds.

    Deffo impressive work. Don’t want to bring them down. I just don’t like paying AI tax to gate keepers for each use.

    I had a look under the hood of browser-use. I wanted to to run some tests with a local browser and a trusted LLM provider of my choice, but the (enabled by default) telemetry they send to PostHog is CRAZY. Especially the browser-harness component can leak credentials to PostHog left and right.

    This is absolutely not cool.

    You do not do all this with google flights. The link can be constructed with protobuf.
