What would you build differently if you owned the weights?

Tomorrow LTX, @bria_ai_, and @fal discuss what the open generative media stack changes for product teams. #NYCTechWeek

@EfrenBlackjack @JomboyMedia F*** Utley now and always.
--every Mets fan.

[Rachel Luxemburg @rlux]

I just can't even with the Mets.
What a waste of talent and money.

Stearns has to go.
Mendy too, but this is more on Stearns than anyone else.

Honestly wondering if we'll still have Soto and Lindor by the end of the year.

This is a great encapsulation of the space.

@SlipperyGem Creating the Comfy nodes is pretty straightforward

[Rachel Luxemburg @rlux]

LipDub for LTX-2.3 dropped last week, and the most common question I've seen has been: how is this different from lipsync?

I wrote a quick guide on when to use each. It's especially relevant if you're working on dialogue or localization workflows.

@michaelgbaron @FactsFactsFact1 this is 100% on Sterns, not Mendoza.

[Rachel Luxemburg @rlux]

This is not primarily a Mendoza problem. Firing him will not fix it.

This crapfest is on Sterns.

[Michael Baron @michaelgbaron]

4 different third basemen.
4 different first basemen (none are actually first basemen, btw).
4 different shortstops.
8 different lieft fielders.
3 different center fielders.
5 different right fielders.

Meet the worst team in baseball - the 2026 #Mets.

We've just hit 1M open datasets on the Hugging Face Hub 🎉

Open models need open data. Today we hit that milestone, together with the most incredible community in AI! 🤗

Onwards to the next million 🚀

@tipping_pitches LOL I got the Cubs....
Lifelong Mets fan though so it's not a complete miss

#SIGGRAPH2026 accepted!

Our paper on joint audio-visual diffusion for video dubbing, has been accepted to SIGGRAPH 2026.

You take a finished video, change the dialogue, and the lips re-match across angles, occlusions, and varied lighting. No reshoot needed.

Read the paper below.

@DodgersNation They already reviewed it & called it trash.

[Rachel Luxemburg @rlux]

@SleeperMets i saw it live and I still didn"t believe it. 😂

[Rachel Luxemburg @rlux]

@JoelMetsNY He and Sam Rosen both. NYC owes their legends so much better than this.

[Rachel Luxemburg @rlux]

@just_mets utter disgrace
