There is finally an open world model you can download and run on your own machine.

It's called LTX-2.5, from Lightricks, and it's built for film production, real-time experiences, and physical AI.

It comes with native 4K and HDR, native multi-shot scenes, and editing of your own real footage, on top of text-to-video, image-to-video, and audio-to-video generation.

The craziest part? 

The full 22B-parameter weights are open, so you can fine-tune it and run it on your own GPU, with no data leaving your machine. 

It's free for companies under $10M in annual revenue.

A 27B open-source model just took #1 on Artificial Analysis 🤯

Drex Max 1.1 from Nace AI picks between options across text, images, and video, and it's small enough to run on a Mac.

Runs on your own machine.

Small specialized models are winning.

Drex Max v1.1 is #1 on Decision Index @ArtificialAnlys and going open-weight soon!

Both achieving SOTA and Pareto frontier, it’s one of the fastest & most capable Decision models today

Drex API: nace.ai/drex (~1M free requests)
Paper: arxiv.org/pdf/2611.07854

Make better decisions.

You can now reverse-engineer any web animation into your own code.

It's called reanimate, a free Claude Code skill.

Ask an agent to rebuild a motion from a screenshot and it usually guesses once and stops.

reanimate films the original, rebuilds it in your stack, films the copy the same way, then compares timing, easing and pixels until the numbers match.

What you can feed it:

- A live website URL
- A screen recording
- An mp4 or gif
- A Lottie file

It writes into what your project already uses: CSS, Framer Motion, GSAP or three.js.

Usually 2 to 5 fix rounds. Whatever still doesn't match is listed in the report.

Install: npx skills add NiazMorshed2007/reanimate -g

A voice model just got small enough to run inside a browser tab.

It's called Woof, from Underdog. One voice is 31.7 MB. Two voices are 40.6 MB.

No server. Once it's loaded, you can go offline and it keeps talking. I set my browser offline and recorded it.

What makes it interesting is the hard text. Phone numbers, dates, prices and codes are where small voice models fall apart. Woof runs everything through a text normalizer first.

Underdog's own numbers on 500 hard sentences:

- Two-voice Woof: 1.42% of words wrong
- Fish Audio Drama 3: 1.89% wrong, and a 41.5 GB download
- One-voice Woof: 2.06% wrong

So it's about 1,000x smaller, with similar accuracy on their test.
