World-class AI performance, meeting everyday life. @BiltRewards 👋
A chip the size of a dinner plate, to help you book your next dinner. @BiltRewards selected @Cerebras to power its Neighborhood OS and AI assistant, Bilt Concierge. More than 8 million people across the US use Bilt to earn rewards on rent. Bilt allows members to spend those rewards at 50,000+ local merchants. Now, with Bilt Concierge, an AI agent can do it for you. Just ask it to book a table, plan a trip or shop locally and it’s done. With Cerebras, those services will be near instant. World-class AI performance, meeting everyday life. Excited to partner with @ankurjain_2 and the @BiltRewards team.

Moonshot just dropped Kimi K3.1 Pro. We used it to speed run online shopping. One prompt → monitor found → checkout → order confirmed. 11.5 seconds. Watch @Kimi_Moonshot K3.1 Pro in action, accelerated by Cerebras.

Last week, short seller @CulperResearch, published a report arguing that Cerebras wafers wear out after about two years. Nearly every financial conclusion in that report depends on that one number. That number is wrong. How long our systems last is a fair question, so we want to address the topic plainly. Read our response on our blog. cerebras.ai/blog/what-it-too…

On Big Chip Club, @MilksandMatcha talks with @cdngdev, the former @OpenAI robotics intern behind this summer’s viral Astra robot-painting demo. They discuss the creative process behind building products people want to make for themselves, why robotics needs fast inference, and what recursive self-improvement (RSI) would require. 0:00 Meet Thijs: Discord, OpenAI, and Stanford 0:47 Building a wardrobe app in a day 3:17 Making demos that cut through the noise 4:43 Whimsical and practical demos 5:25 Where good ideas come from 7:04 Teaching a robot to paint the Golden Gate Bridge 8:52 Improving the robot’s painting ability 10:34 Giving Sam Altman the robot’s painting 12:00 Why robots need fast inference 14:11 What demos should Cerebras build? 15:07 Getting started with robot arms 16:33 Recreating apps and 3D models on demand 17:56 From generated models to physical things 19:45 Inside OpenAI 20:17 What RSI means 23:11 Getting AI's benefits to everyone 24:39 Personal assistants for everyday tasks

Breaking it down with Sean Lie, our CTO, How we deploy Trillion-parameter frontier models on Cerebras
How we deploy multi-trillion parameter models at scale Today, let's break down the math for how @cerebras: 1. Fits the full model into on-chip memory 2. Maps the model across multiple chips 3. Handles a high # of concurrent requests
There's a new version of this post

The new physics of cybersecurity makes inference speed essential. Defenders now need to detect, reason, and act so much faster than attackers. Read more about how Cerebras is partnering with CrowdStrike to accelerate that defense loop 👇 Thank you, @gdb, for highlighting how AI-enabled cybersecurity is more critical than ever!
OpenAI took 25% of its production engineers off every project and told them: you are just securing now. Their top model hunted in their infrastructure until it saturated (stopped finding new issues). Will everyone else follow? New physics of cybersecurity @gdb / @NoPriorsPod

Your AI agent has a to-do list. Waiting shouldn’t be the longest item. Cerebras’ Andy Hock joins theCUBE to discuss why inference speed matters for reasoning models and AI agents. Where would less waiting make the biggest difference? Watch the full conversation with Andy Hock and theCUBE: youtube.com/watch?v=H2GnroPz…

AI agents rely on a good harness. Faster inference gives a harness room to inspect results and recover sooner, while you steer the work. @MilksandMatcha breaks down the loop.

“If you’ve ever asked AI to do something and then drummed your fingers waiting for it to respond, you’ve run up against slow inference. To pick up the pace, Cerebras developed its own inference platform from the semiconductor wafer up.” Cerebras is proud to be named in @FastCompany 's 2026 Next Big Things in Tech list.
