ok ai agents renting their own iphones is kind of wild
no api, it just taps and types like a person would
i love it but i also need to know who gets blamed when mine orders 40 burritos at 3am
Give your agents their own iPhone and Mac.
Al agents are smart enough to do almost anything, but they've been missing the one tool every human uses:
A device.
Introducing Glasshand.
Glasshand lets your agent tap, type, and swipe on real iPhones and Macs, exactly like a human.
That means it can:
→ Post TikToks
→ Book Uber rides
→ Send iMessages
→ Download any app it needs
If a human can do it on a device, your agent can too.

AI agents have phones now 😭
They can text you, post on tiktok, order food and use apps without needing an API for everything
Not sure if this is genius or the beginning of a very weird internet

a 16 year old just got into yc to build ai-guided weapons
henrijs is the solo founder of polemos, with a team out of nasa jpl and caltech
they're even building their own propellant supply
and you're still waiting for the right time to start
Launching @polemos_inc (YC F26) today.
Precision strike was built for a different era: expensive, slow to produce and fielded in small numbers. Polemos is building it for the war that’s actually coming, with networked launch systems that strike in mass and AI guidance carrying every round through the terminal phase. It’s all designed to be mass-produced from day one, to protect us from the warfare of tomorrow.
Precision, at scale.
Shoutout to @zeroonecreative for the video

casi todos los pipelines de documentos tienen un portero en la puerta
mira cada pdf y decide: este es fácil, al OCR barato. este es difícil, al parser caro
y el portero se equivoca. el pdf "fácil" del proveedor trae una tabla con celdas combinadas en la página 37 y te toca reenrutarlo a mano
ese portero solo existe por el precio. con r-1 mini de Reducto a $1 cada 1.000 páginas, yo probaría a quitarlo: todo por el mismo sitio, una sola rama, un solo formato de salida
empezad por el pdf más feo que tengáis y véis que tal

AI agents having their own iPhones is kind of crazy.
They can text you, post on TikTok, call an Uber and even order DoorDash, just like we do.
Pretty exciting, but also makes you wonder how far we should let this go.

Blueface starts to play a very controversial song once he saw a call coming in from Chrisean😭😂🔥.
This guy is one hell of a character 😂.
Imagine joining a company and your first week is a fully paid luxury vacation.
That’s what @getserval is offering new engineering hires.
Not your usual onboarding experience.
Starting today, every engineer who joins Serval begins with a weeklong, $10,000 paid vacation. We’re building the next generational company. We need generational talent to see it through.
Our mission has always been to empower people across every team to turn their understanding of a problem into working, trustworthy automations. Making that function inside the largest enterprises takes world-class engineering.
That’s what you’d be joining us to do. There are foundational decisions still to make, and the engineers making them will shape the future of how big we can build this company.
We want you to arrive rested and ready to do the best work of your life. So your first week is a chance to get away.
And if a @getserval employee refers you, both you and that employee receive $30,000, on top of the vacation.
Come build with us: serval.com/careers

Por qué se habla tan poco del precio de "entender" un documento cuando estás buildeando agentes??
Me explico: el modelo ya puede razonar, extraer y decidir, pero si cada PDF, contrato o reporte te sale caro de procesar bien (tablas, figuras, formato y todo), terminas limitando el volumen o bajando la calidad.
Ese costo silencioso acaba frenando más de lo que uno cree, estoy completamente seguro que más de uno se habrá chocado con este muro porque a mí también me ha pasado!
[Reducto]
Estp le interesa mucho a los que trabajan con OCR. Esta gente está sacando un modelo de parsing llamado r-1 mini, este gigachad mantiene calidad alta a $1 CADA MIL PÁGINAS.
Según lo que muestran, le gana en precisión a varias alternativas que ya conocemos.
Vale la pena que le echen un ojo si están trabajando con OCR porque esto implica que ahora a tu agente puedes darle acceso a documentos reales a escala sin que el presupuesto se te vaya a las nubes!
Este son el tipo de productos que me gustan mucho 😊
Samuel Urdea retweeted
Models are becoming smarter, faster, and cheaper, but the OCR industry hasn’t kept up.
We’re launching r-1 mini: the first model to offer truly premium parsing without the premium pricing. At $1/1000 pages, r-1 mini beats options that cost up to 25x as much.
Samuel Urdea retweeted
As some of you know, I was born with a rare and serious condition.
It's called Documentitis, and it flares up when I'm exposed to expensive and inaccurate document parsing.
That's where Reducto's new r-1 mini comes in. Industry-leading parsing accuracy at $1 per 1,000 pages 🧵

AI went from text to voice.
Live video is next, and Atmee v2 feels like a real step there 👀
One image + 10 seconds of audio and you get an avatar you can actually video-call.
Human or a cartoon animal.
Paste one setup link into your coding agent and it wires up the API.
The timing and motion in the launch video are what got me @yuchenping @Atmanity
After Google acquired my AR startup, I started thinking about the next interface, this time for AI. Text and voice work fine, just like DOS did before the Mac. But nothing’s more intuitive than face to face.
After two years of research, today we’re launching Atmee v2: a real-time avatar model that makes live video agents feel truly life-like.
• Any character from 1 image + 10s of audio
• Contextual expressions, gestures, even interacting with the environment
• Live video calls, voice only, or video generation
At its core, Atmee v2 is a video foundation model, it can render anything, but it’s built to excel at characters, which is what video models like Seedance 2.5 and Wan 3.0 are mostly used for. In comparison:
Atmee v2
• Up to 50x faster
• 10-100x cheaper
Build tutors, sales coaches, support agents, companions, game characters, even whole living worlds. The interface after text and voice starts today.

CLAUDE AND CHATGPT JUST LEARNED TO COMPOSITE.
Tesseract added 3D, and the interesting part isn't the 3D on its own.
It's that your agent can put an animated 3D character and 2D typography and graphics in the same composition.
Two types of people will see this:
Person 1: still exporting renders from one app to drop them into another
Person 2: asking their agent for the whole shot at once
What that unlocks:
→ a 3D mascot presenting your launch, with the headline animating next to it
→ a character reacting to a stat that counts up on screen
→ animated titles moving through a scene with real depth
→ a launch intro built in one go instead of across two tools
The 3D was never the bottleneck.
Putting everything together was.

PROBABLY ONE OF THE BEST X ACCS THAT I EVER SEEN, FOLLOW HIM I”LL NOT SAY ANYTHING MORE…
ESTE REPO LE QUITA LOS ANUNCIOS A TU TELE. GRATIS!!
se llama cleanyourtv y funciona así:
activas la depuración en tu tele Android, le das acceso a Claude Code o Codex por Wi‑Fi y él se encarga del resto en unos 15 minutos
lo que hace:
→ desactiva la publicidad de la pantalla de inicio, las filas patrocinadas y el rastreo del fabricante
→ te pone una pantalla de inicio limpia estilo Apple TV, de solo 572 KB
→ no borra nada, solo desactiva, y tiene un script para deshacer los cambios
→ antes de tocar algo que puedas usar, te pregunta
ya funciona con más de 420 modelos de más de 100 marcas
y lo mejor es cómo empezó: el creador solo quería limpiar la tele Xiaomi de sus padres. unas semanas después tiene más de 50.000 estrellas en GitHub y llegó a ser el repo número 1 en tendencias de la semana
lo que los fabricantes te venden como "smart TV", resulta que se arregla con un prompt
el repo, en el primer comentario 👇🏻

Claude ya puede hacer 3D
Esto es Opus 5.5 + Tesseract renderizando una escena completa con ray tracing
Hay gente ganando +10K$/mes con canales de documentales sin mostrar la cara como este
Puedes empezar uno hoy mismo solo con Claude. y Tesseract es totalmente gratis
El workflow:
1. Pídele a Claude 10 ideas de documentales de tu nicho y quédate con la que tenga mejor gancho
2. Pide a Claude que te escriba el guion completo dividido en escenas
3. Para cada escena, Claude monta el plano 3D en Tesseract. movimientos de cámara, iluminación, texto animado
4. Mete tu voz en off y dile a Claude que sincronice los planos con ella (o pídele a Claude que locute el vídeo por ti)
5. Retoca lo que quieras con una frase. "cámara más lenta", "luz más cálida", "título más grande". solo cambia eso
De la idea al vídeo terminado sin abrir un editor
🤝 Paid partnership
Opus 5.5 or Astra can now create professional-grade 3D outputs with path-traced rendering.
Using Tesseract with your agent, you can simulate how light moves through a 3D scene, bounces off surfaces, casts shadows, and creates reflections.
The video below was created without Blender or video models, and it remains fully editable.
