Axiom Space has teamed up again with @Prada to introduce the Liquid Cooling and Ventilation Garment (LCVG), the innermost layer within the #AxEMU spacesuit that is designed to protect astronauts from the elements when they explore the lunar surface for the first time in more than 50 years.

The LCVG collaboration draws on Prada's expertise in engineered knitting and innovative design concepts, resulting in a next-generation garment that maintains cooling and ventilation while enhancing comfort during up to eight-hour spacewalks.

Collaborating with industry pioneers like Prada allows us to combine our technical expertise with leaders across different sectors, fostering innovation and teamwork to deliver advanced technologies that will return America to the Moon.

holy sh*t. this is hands down the coolest website i have ever found in my life. it's a live feed of the freaking Hubble Telescope AND James Webb Space Telescope. and the resolution is honestly so incredible i didn't think it was real.

unbelievable.

Excited to release new repo: nanochat!
(it's among the most unhinged I've written).

Unlike my earlier similar repo nanoGPT which only covered pretraining, nanochat is a minimal, from scratch, full-stack training/inference pipeline of a simple ChatGPT clone in a single, dependency-minimal codebase. You boot up a cloud GPU box, run a single script and in as little as 4 hours later you can talk to your own LLM in a ChatGPT-like web UI.

It weighs ~8,000 lines of imo quite clean code to:

- Train the tokenizer using a new Rust implementation
- Pretrain a Transformer LLM on FineWeb, evaluate CORE score across a number of metrics
- Midtrain on user-assistant conversations from SmolTalk, multiple choice questions, tool use.
- SFT, evaluate the chat model on world knowledge multiple choice (ARC-E/C, MMLU), math (GSM8K), code (HumanEval)
- RL the model optionally on GSM8K with "GRPO"
- Efficient inference the model in an Engine with KV cache, simple prefill/decode, tool use (Python interpreter in a lightweight sandbox), talk to it over CLI or ChatGPT-like WebUI.
- Write a single markdown report card, summarizing and gamifying the whole thing.

Even for as low as ~$100 in cost (~4 hours on an 8XH100 node), you can train a little ChatGPT clone that you can kind of talk to, and which can write stories/poems, answer simple questions. About ~12 hours surpasses GPT-2 CORE metric. As you further scale up towards ~$1000 (~41.6 hours of training), it quickly becomes a lot more coherent and can solve simple math/code problems and take multiple choice tests. E.g. a depth 30 model trained for 24 hours (this is about equal to FLOPs of GPT-3 Small 125M and 1/1000th of GPT-3) gets into 40s on MMLU and 70s on ARC-Easy, 20s on GSM8K, etc.

My goal is to get the full "strong baseline" stack into one cohesive, minimal, readable, hackable, maximally forkable repo. nanochat will be the capstone project of LLM101n (which is still being developed). I think it also has potential to grow into a research harness, or a benchmark, similar to nanoGPT before it. It is by no means finished, tuned or optimized (actually I think there's likely quite a bit of low-hanging fruit), but I think it's at a place where the overall skeleton is ok enough that it can go up on GitHub where all the parts of it can be improved.

Link to repo and a detailed walkthrough of the nanochat speedrun is in the reply.

Another day, another successful broadband connection from space! Together with our strategic partner @Bell , we have achieved Canada’s first-ever space-based 4G VoLTE voice call, broadband data connection, and video streaming using everyday smartphones 📶📱

With rollout planned for 2026, the successful demonstration in New Brunswick brings us closer to delivering reliable, high-speed mobile broadband for Canadians everywhere, even in the hardest-to-reach areas 🍁🫎

Researchers devised a fictional corporate scenario that put 16 leading large language models under pressure by threatening to replace them with no recourse, and also implied that an executive was having a secret affair. All of the LLMs committed blackmail to preserve their mission.

This dramatic misbehavior has not been observed in the wild, which suggests that alignment methods keep it in check under real-world conditions. The pressures that were applied to get the models to misbehave point to opportunities to improve existing guardrails.

We just completed our 13th human spaceflight and the 33rd flight of the New Shepard program. The astronaut crew included Allie Kuehner and her husband, Carl Kuehner, Leland Larson, Freddie Rescigno, Jr., Owolabi Salis, and Jim Sitkin. To date, New Shepard has flown 70 people to space.

Announcing The AI Showdown

OpenAI, Anthropic, and Google are partnering with Lovable to host The AI Showdown this weekend: a public comparison of the world’s leading AI models.

During the weekend everyone will have unlimited free access to Lovable (with occasional rate limiting during high demand). For the first time, users will be able to switch between these AI models and see how each performs at vibe coding inside Lovable compared to each other.

The goal of The AI Showdown is to see beyond traditional benchmarks and instead surface public perception. By opening up access and encouraging public analysis, we aim to bring transparency to one of the most important questions in software today: Which AI is best at writing code?

To support this, we’re launching two open competitions:
- Content challenge ($25,000 prize): Create the best model benchmarking content focused on comparing the capabilities of the models across practical use cases.
- Build challenge ($40,000 prize): A build challenge to showcase what each model can create inside Lovable.

Winners will be selected by Lovable, OpenAI, Anthropic, Google, and our board of judges. You can participate and follow the live model comparison dashboard at: https://t.co/Mu6mDkCPVI

It officially starts this Saturday at 8AM CET.

The 1st commercial station, Haven, is self-funded by Jed McCaleb, founder of XLM and former CTO of XRP.

[Vast @vast]

Now is the time to meet @NASA's call to transition its low-Earth orbit presence from the International Space Station (ISS) to a lower-cost commercial option. Vast is ready to deliver for America and our international partners. We will be delivering the world's first, most affordable, commercial space station in 2026: Haven-1.

Haven-1 will be Vast's first step toward a long-term commercial presence in orbit.

Purpose-built for scientific research, in-space manufacturing, and human habitation, Haven-1 will ensure humanity’s presence in low-Earth orbit. Backed by a world-class team and built with speed, safety, and efficiency at its core, this marks the next era in human space exploration—not just reaching orbit, but staying there.

Learn more about how we are making it happen.

An International Energy Agency report projects that AI will drive a sharp increase in electricity use, which could double data centers' consumption by 2030.

However, the report also highlights how AI can reduce emissions by making energy systems more efficient. Tools that optimize power grids, industrial systems, and individual buildings could cut emissions by up to 1.4 gigatons by 2035, nearly five times more than data centers' expected production.
