time for some vacation stuff
Yesterday was my last day at @LumaLabsAI.
Over the last three years, I had the privilege of helping drive the company's transition from 3D AI to video generation and native multimodal foundation models.
I am grateful to have worked alongside an extraordinary group of researchers, and I look forward to seeing the next chapter of the company's story unfold.

1/ muse spark open is the most capable US open-weight model to date.
816B total params, 42B active. 1M-token context. natively multimodal. built for coding and agentic work like long-horizon tasks, hard software engineering, multi-step reasoning.
america! 🇺🇲

Muse Spark Open -- weights releasing today -- runs great on new Mac Studios thanks to work with @johnternus and Apple.
$52M seed round. 15M+ users. But this is what we're most proud of yet.
Introducing Drama 3: the most emotive and controllable TTS model in the world
And yes, it's open-weight.
You can now control how even a single word should sound, change its tone, and shift your voice mid-sentence.
Uncle Roger was impressed too.

We have a huge pivot underway here at Epic, moving developers around to retool for maximum AI acceleration.
The aim isn't to do the same stuff with fewer people, but to enable everyone here to build MORE and BETTER stuff, and to bring the benefits to all teams using Unreal.

Today we are launching Muse Wonder and Muse Wonder Full, our best models yet, with state-of-the-art performance on personal and professional agentic tasks. They are built for long running, multi step work. Muse Wonder is available today in the Meta Model API and Muse Code, and Muse Wonder Full in Muse Code.

We launched 🍉 (Muse Wonder) and 🍉 Ultra (Muse Wonder Full) today!
What excites me most is how much closer we’re getting to agents you can actually delegate work to. Personal agents that understand you and your life, and professional agents that can take on complex, long-running projects. 🍉 is designed for personal and professional agent use
Pretty Wonder Full to see this come together just a year after starting the agent team at TBD Labs. Huge credit to the incredible team that made it happen!

🍉 🍉 🍉 Muse Wonder and Muse Wonder Full is here. A new series of model where we push hard towards the personal superintelligence mission. The models achieve sota on internal personal and professional agent tasks across domains. Try it out today!

5s of video, generated in 1.3s!
Nunchux brings @MiniMax’s MiniMax-H3 to @AMD MI355X with up to 26.7× faster inference than SGLang on 8 GPUs @AMDServer
And with streaming generation, you can change the prompt as the video plays, steering what happens next.
One stack, optimized across hardware.
Free access to MiniMax-H3 is coming soon! Join the waitlist now at nunchux.ai.

Its kinda amazing how much @Muse can do in so little space (image was from yesterday and yes I saved $20 as a free user)

i collect vintage pens
when @alexandr_wang first sent me a TestFlight to this, i was in Amsterdam and just abt to go to bed
an hour later, i texted him with ‘holy shit’
it completely changed my travel plans the next day, and helped me find a rare pen i was in search of

1/ today we're rolling out Muse, our new personal ai assistant. Muse is always-on, wicked fast, can use a browser, connect to your apps, and is designed to be secure.
try it now: muse.ai.

We're launching @muse, our new personal AI agent! Always on, fast, and built to be private, safe, and secure. Our biggest focus was the security architecture underneath. Each Muse runs in its own secure VM, a separate Sentinel checks every action, it never sees your passwords, and it asks before anything sensitive. More here: security.muse.ai
Uh oh
Many startup employees do not recognize the sheer litany of ways that a founder can screw you over without you even knowing. Founder trust is one of the most important things to look at when you’re joining a startup.
From cutting you out of M&A, screwing your retention pool, overdiluting your equity, firing you before your cliff, not having attractive options exercise plans, poor 409a price management, not telling you about QSBS / early exercise, blocking you from participating in secondary, obscuring company performance and many more.
Many many decisions that are made in rooms you are not in as an employee where the only thing that matters is: “does the founder have your back?” Great startups with untrustworthy founders lead to poor outcomes and often good startups with trustworthy founders lead to great outcomes.
Pick wisely.

I’ve had a lot of fun exploring Muse Spark 1.3 max!
Muse Spark 1.3 also brings exciting progress in visual coding, where advances in coding, agents, CUA, and multimodal converge to transform a spark of imagination into a vivid, compelling experience. Please give it a try!
Jiaming Song retweeted
1/ we just publicly released Muse Spark 1.3 max!
we see significantly stronger coding and agentic performance on muse spark 1.3 max, so would strongly recommend trying it out even if you've already tried muse spark 1.3 high or muse spark 1.3 xhigh.

Today we're releasing Muse Spark 1.3, our strongest model for agentic and coding tasks in the spark model line. It’s designed to support longer-horizon work, excel in agentic tasks, and follow complex instructions more reliably than previous models. Muse Spark 1.3 is available today in Muse Code and Meta Model API.
