We have a new coffee grinder (and $190M fund). I rebuilt the electronics to add grind-by-weight and Wifi/BLE. The firmware is also running a server to announce our new fund: rootventures.coffee/ ☕️🚀🤑

Doing more speaking engagements recently. Realizing I’m balanced between smart / ridiculous sounding soundbites. 🛼🤖

My framing of the humanoids vs specialist. Once the humanoids take over the robot-building factory, will they be vain and make more humanoids or will they build a use-case specific form factor?

Had a great time hosting this panel for a packed house of students at @HarvardHBS. Thank you to Rob Playter (ex-CEO Boston Dynamics) and Dave Johnson (CPO of Walden Robotics)

I like to dream that he had Muse Gadgets running on this
A 35-year-old Saudi national employed by OpenAI, Abdulrahman Alfozan, has been arrested for allegedly installing a covert audio recording device at the company’s San Francisco headquarters, officials say.

Solid advertising for @seeedstudio You can really build anything
BREAKING: OpenAI engineering lead arrested by the FBI after hiding a covert audio recorder inside an executive conference room at OpenAI HQ Abdulrahman Alfozan is 35, MIT-educated, ex-Meta, ex-Nash and reportedly their only Saudi employee, has been terminated, first federal court appearance today.

Side quest complete.
Replying to @AstasiaMyers
One slight modification.

We embodied Muse in the office coffee grinder
🚨 side project alert 🚨 Announcing Muse Gadgets, an open source ESP32 firmware and Linux sdk so that you can make hardware devices that work with Muse. Grab an API token from gadgets.muse.ai and point your favorite coding agent at the github repo to build your own peripherals for Muse.

Sharing artifacts, gh repos, static chats, MD files....all lame. I just want them to jump into the chat! Hooray for multiplayer agent surface.
Delta is now in public beta. It’s a multiplayer environment for coding with agents and reviewing what they build, with every code change linked to the conversation that produced it. Anyone can download it today on macOS, Linux, and Windows: delta.dev/download

I remember going to the DARPA challenge in 2015. Progress seems slow when you are watching closely. Don’t get discouraged by everyone’s “rapid progress”, put in the work.
Quick reminder: this was the state of robotics just 11 years ago

Big news for those following voice agents
Introducing PhoneLLM, an open model for voice agents. GPT 5.6 Terra performance on typical voice agent tasks at 1/3 the latency and 1/18 the cost. For voice agents, we need models that are both very low latency and very good at tool calling and instruction following. There's a trade-off here, and we often have to compromise on either latency or capability when building voice agents. With PhoneLLM (and the training and data stack that made this model possible) we're fixing this problem. For the last couple of years, most of the effort in frontier model development has gone towards leveraging test-time compute. Which is awesome! Models of all shapes and sizes are available that perform really, really well ... if you have "thinking" turned on for your model. But if you need your agent to respond at voice conversation speed, you can't use thinking models. PhoneLLM is a full-weights fine-tune of NVIDIA Nemotron Nano 30B. We trained on a wide range of real-world telephone and customer support use cases. The training focused on taking the excellent Nano 30B base capabilities and teaching the model to do typical voice agent tasks with thinking disabled. The results are really good: accurate tool calling and concise, on-topic responses in long conversations. And fast: TTFAT measured server-side is <100ms if you run PhoneLLM on a lightly loaded B200. :-) But seriously, when we characterize model latency, we do it with full, end-to-end, batched request simulations using real Pipecat voice agent pipelines. You can serve more than 80 concurrent agents on a single B200 with P95 end-to-end TTFAT <600ms. Including network overhead. That's an LLM cost-per-minute around $0.0025. (1/4 of a cent.) At a latency lower than any third-party API offers today. More details about this model, including weights on @huggingface, how to spin it up with one click on Modal, and a starter project repo you can clone, are in the thread ...

Going from sharing AI coding session output to sharing the sessions themselves.
Today we’re introducing Delta. Delta is a multiplayer environment for coding with agents and reviewing what they build, powered by DeltaDB. The first invites to our private beta are going out now. zed.dev/blog/introducing-del…

my only memory of eating in the restaurant at the top of this building was using the urinals -- they placed them against massive windows overlooking the city. I can only imagine the architectural conversation around that one...
テキストや図面でAIエージェントと対話するだけで、台北101の詳細な構造モデルをつくり、パラメータまで調整できる? これはPlamoで実際に行ったVibe Modelingです。

AI-first aircraft development: parametric geometry generated at scale without failures, Physics AI models reporting lift and drag across a wide design space, and multi-objective optimization to get to the most performant aircraft. All in minutes instead of weeks or months.

I vote for (in no particular order) 1. Wembley 2. Madison square garden 3. Wrigley 4. Yankee stadium (old) 5. Lambeau 6. Rose Bowl 7. Fenway 8. Roman coliseum
As New York and New Jersey get ready to host the world’s biggest match, we recreated the stadium where history will be made. We uploaded an image of the iconic MetLife Stadium into Plamo and worked with the AI agent to build a fully editable, parametric 3D model. What iconic sports venue should we vibe model next?

The irony of Nix is that it was always a great solution for the government / defense industry to protect their surface area (despite a small vocal group in the community). Now there is a clear path for those agencies to get the power of Nix and more!
FlakeHub has achieved FedRAMP High Authorization and is listed in the FedRAMP Marketplace 🎉🏛️🔐 This makes Determinate platform features like secure Nix packages, binary caching, and private flakes available to U.S. federal agencies and orgs handling Controlled Unclassified Information (CUI). Nix's reproducible builds, sandboxing, and other supply chain features make it uniquely well suited for the highest-stakes environments and we're thrilled to finally bring it inside the FedRAMP boundary.
