Pleased to see Chiricahua's elevation to National Park status. By far the most impressive "National Monument" I had visited and significantly more interesting than many of the "parks".

Transform your agent's wall of text into something interactive with spacesheep, from my good friend Michael who built a lot of Claude code artifacts.
My agents sent me 355 hours of reading this week. I can't read that fast. We're launching Spacesheep (YC F26) to fix that: agents' work lands in a space your team can actually understand and work on together. Try it: tell any agent "share this to spacesheep.dev"

Initial impression of Dot: the router between the Dot conversation and the underlying execution conversations is very lazy and it will reuse totally unrelated conversations for new tasks.

This is high art.
I made this with one prompt using Opus 5.5 I spoke to my computer for 5mins, claude worked for 12 hours, and I woke up to this full prompt:

I built BoxHaven - open source dev boxes for Claude Code and Codex. It has completely changed my dev workflow. Now I work inside a single orchestrator session that delegates many tasks in parallel to many dev boxes. Here's a demo of 5 agents building redesigns for boxhaven.dev. Here's the repo: github.com/finbarr/boxhaven

I added a new feature to Kyoto Bounce where you can step outside of the suggested start area and create your own line to maximize points. Here's a replay: kyotobounce.com/replay/15d75…

This but for gaming. It's gonna be lit!
you can just hallucinate the entire internet with Qwen 3.8 27b running at 2,000 tokens/second? part 2 of turning @cerebras + @Alibaba_Qwen 3.8 27B into an OS: built an offline browser with zero network calls and mounted it directly the JIT ubuntu desktop. no wifi. no scraping. zero packets sent to external CDNs. you search a site, set a year, and qwen 27b at 1,950 tok/s synthesizes the entire DOM on the fly. here is youtube in 2045 vs 1999: → search google for youtube inside the OS → scrub to 2045: instant futuristic feed → scrub to 1999: raw web 1.0 time capsule in seconds at this speed, browsing isn't retrieving files from a server, it's querying an alternate reality. a 2D browser window is just step zero. imagine full operating systems, virtual worlds, and complex simulation engines existing purely as model weights. zero gigabytes stored on disk, just pure interactive reality streamed on demand. What else becomes a possibility with the qwen 3.8 27b (dense) at 2000 tokens/sec?

Awesome to see a team creating new AI paradigms. We're still so early.
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

Is AI safety incompatible with acceleration? Who is working on trying to make AI safer while maintaining the rate of improvement?

Huge congrats @chooi_jeq! Robocurve is the benchmark for evaluating robotic capabilities and they just raised $10m.
We raised a $10M seed for @Robocurve, an independent Public Benefit Corporation, to evaluate frontier AI in the physical world. In less than 3 months, our research has been viewed 6M+ times and our evaluation harness downloaded 97k+ times. Researchers from 200+ institutions, including 19 of the world’s top 20 universities, have signed up to build benchmarks with us. We welcome more independent evaluators. The more third-party evaluators, the better society can understand how fast robotics AI is progressing. Our evaluation harness is fully open-source, and we publish benchmarks anyone can run and verify. Our round is led by @Initialized, with participation from @notablecap, @decasonic, @ycombinator, @HalcyonFutures, and many others. Building robots or frontier AI? Work with us to help the world understand what your systems can do.

I made a game kyotobounce.com. You play as a robot who likes to bounce balls around inside the atrium of @ksb_official901.

Got a license for that DGX Spark?
Coming soon to a regulated AI future near you!

Working at @ycombinator this summer has been awesome. There are amazing companies in robotics, space, defense, biotech, hardware, AI and more. Excited to see them all debut at demo day tomorrow!
