Alexandr Wang says Meta has been working on Muse since February. the prototype took 1-2 weeks.
but they spent 7 months on this:
> 100+ specific agent behaviors were tracked in a spreadsheet
> each with its own eval and a launch-blocking threshold
> it was only after Muse Spark 1.3 that all 100 were green
> under 200 people across model + product
this explains the 7 month gap. OpenClaw had a magic moment but broke all the time, so most people just dropped it.
Meta understood from OpenClaw’s lesson that reliability IS the product. whether it holds up for millions of users is another story though.
