We've probably all seen demos of live voice agents and image / video generation models. Putting all these capabilities together live and making it easy to integrate on day one is an incredible feat.

Congrats @lina_colucci @sidney_primas and team on the launch!

Give your voice agents a face.

Introducing Lemon Slice-2 – the world's first interactive talking AI video model

Think of it as a face layer for your voice agents, available today in production as an API or an embeddable widget.

What makes Lemon Slice-2 great:
→ Easy: All you need is 1 photo
→ Expressive: hands and full body motion
→ Any character and style: if it has a face, Lemon Slice-2 can animate it

Under the hood: we trained a custom, 20B-parameter video diffusion transformer, streaming at 20fps on a single GPU. Infinite-length video generation with no error accumulation.

Talk to the demo avatars on our homepage.
Or, add your own interactive avatar to your website.

Companies and creators are already building video agents that are:
→ Customer support agents who screen-share and show you where to click
→ Lead qualification agents that replace forms with real conversations
→ AI personal shoppers who try on clothes and guide purchases

People don't engage with chat bubbles. They engage with faces. And now you can have a 24/7 spokesperson that’s the face of your brand.

We’ve partnered with @elevenlabs, @trydaily, and @modal to make this happen.

As part of this launch, we’re giving away a guide:
“How to Add a High-Converting Video Agent to Your Website in under 10 Minutes”

Retweet and comment "LEMON SLICE" below and I'll send it over 🍋

The Simular team is proud to share:

🎉 𝗔𝗴𝗲𝗻𝘁 𝗦 has won the 𝗕𝗲𝘀𝘁 𝗣𝗮𝗽𝗲𝗿 𝗔𝘄𝗮𝗿𝗱 at the Agentic AI for Science Workshop at #ICLR2025 @iclr_conf! 🎉

It’s the first open-source computer-use agent, and the first to surpass 20% on OSWorld at at the time of its release in October 2024 — sparking the current wave of computer-use agency.

Since Oct 2024, we’ve moved fast:
✅ Gen 2 released
🚀 Major gains in capability
🔬 More breakthroughs coming soon

Huge congrats to the fearless @SimularAI team @saa1605, @jiuzhou_han, Shuyu, Jiachen, @angli_ai & @xwang_lk!

We’re just getting started. #AIagents #AgentS #Simular

Introducing Lemon Slice Live:
the first real-time audio-video AI model

Anyone can video chat with any character by just uploading a single photo. Every pixel on the screen is rendered at 25fps in real-time by a transformer model.

Here’s how we built it + a live demo! 👇

We just celebrated the grand opening of Seen Health's inaugural center in San Gabriel Valley.

At Seen Health, we're committed to setting a new standard for what aging care can—and should—be.

It's time for our families and communities to be cared for, celebrated, and truly seen.

[Seen Health @SeenHealth]

🎉 A Historic Moment for Seen Health & Senior Care! 🚀

We officially opened our first PACE center on Saturday, bringing exceptional, culturally-focused care to San Gabriel Valley & setting a new standard for aging at home.

Since January, we’ve welcomed seniors into Seen Health care, providing medical services, rehab, social programs, nutritious meals & door-to-door transportation—all designed to help them thrive.

💬 Our participant Rongmei (Emma) Wang shared:
"As seniors, we may feel vulnerable, but at Seen Health, we are seen and supported. Their care honors our traditions—every gesture and detail reflects the respect and kindness we cherish."

Honored to celebrate with:
✨ @RepJudyChu, @AsmMikeFong , the office of State Senator @SashaReneePerez, Alhambra Mayor Katherine Lee, Councilwoman Noya Wang, Monterey Park Mayor Vinh Ngo, @CouncilmanDing, Alhambra Chamber of Commerce, & Astrana Health’s Executive Chairman Dr. Kenneth Sim & Vice Chairman Dr. Thomas Lam.

💡 "We have 12M older adults in the U.S. struggling to find care. Seen Health’s PACE center is stepping up to this challenge." – @RepJudyChu

From a lion dance 🦁 to youth performances & local cuisine 🍜, this was a powerful celebration of community-driven care.

@joshuakelly @Flexpa Awesome work. Is this open source? Happy to collaborate.

[Yang Su @yangsu_13]

@BChillman @olly_wilson @Alex_Kilkka @SimpleHashInc @phantom Another dukie joining the ranks. Congrats @olly_wilson and team.

[Yang Su @yangsu_13]

@fabioberger123 @phantom Congratulations! So excited for this next chapter for you and Blowfish. Also happy you and @BChillman and the rest of the 0x crew are working together again.

[Yang Su @yangsu_13]

We’re excited to share our vision with the world today: a future where seniors are not just cared for, but truly Seen.

Today, we are thrilled to finally share what @sxing13 and I, alongside our incredible team, have been dedicated to for the past three years.

[Seen Health @SeenHealth]

📣 Thrilled to announce the launch of Seen Health today! We’re reimagining senior care, inspired by the personal caregiving journeys of our co-founders, twin brothers Xing Su and Yang Su.

Built on the legacy of PACE, Seen Health combines culturally-focused care with modern tech to create exceptional aging experiences for seniors.

Our first center opens soon in California, and this is just the beginning. Seniors deserve to be truly Seen.

In early 2025, we’ll open our first center in the San Gabriel Valley of Los Angeles welcoming seniors and their families across our community.

[Yang Su @yangsu_13]

Sharing the first bit of our story at Seen Health, a deeply personal venture @sxing13 and I have been building over the last 2.5 years. More to come soon!

Celebrating Lunar New Year is always a family affair. Our most cherished childhood memories are lighting the ceremonial fire (旺火) in Grandpa’s courtyard, setting off endless fireworks in the rural night sky, and eating too many dumplings with our entire family.

Seek to ~1hr mark.
With the newly announced GPTs, I think we’re seeing a new (still a bit primordial) layer of abstraction in computing. There will be a lot more developers, and a lot more GPTs. GPTs that can read, write, hear, speak, see, paint, think, use existing computing as tools, become experts in focus areas, reference custom data, take actions in the digital world, speak or act in custom ways, and collaborate together. Strap in.

[Andrej Karpathy @karpathy]

With many 🧩 dropping recently, a more complete picture is emerging of LLMs not as a chatbot, but the kernel process of a new Operating System. E.g. today it orchestrates:

- Input & Output across modalities (text, audio, vision)
- Code interpreter, ability to write & run programs
- Browser / internet access
- Embeddings database for files and internal memory storage & retrieval

A lot of computing concepts carry over. Currently we have single-threaded execution running at ~10Hz (tok/s) and enjoy looking at the assembly-level execution traces stream by. Concepts from computer security carry over, with attacks, defenses and emerging vulnerabilities.

I also like the nearest neighbor analogy of "Operating System" because the industry is starting to shape up similar:
Windows, OS X, and Linux <-> GPT, PaLM, Claude, and Llama/Mistral(?:)).
An OS comes with default apps but has an app store.
Most apps can be adapted to multiple platforms.

TLDR looking at LLMs as chatbots is the same as looking at early computers as calculators. We're seeing an emergence of a whole new computing paradigm, and it is very early.
