Spent years watching models ace a single image and completely whiff on anything that moves or changes angle. Today we’re fixing that. Try Glimpse now, our first visual thinking model with competitive frontier performance compared to Astra on key public visual reasoning benchmarks.

Meet Nigel. He’s not enjoying our cause-and-effect demo. So I let him sit in the DeLorean. Still not happy. I didn’t write his lines. What he says is generated from his personality and the context of the shot. It’s an entirely new way to create: place imaginary characters in your world, record your performance, and let Simulon generate their reactions and realistically integrate them into your footage. Reality-Aware Rendering is coming to @Simulon this week.

People seem confused about why Tesla is getting so much backlash over its new "flying Roadster." For those of us who were once genuinely enthusiastic about Tesla, this isn't about hating innovation. It's about a long history of broken promises, misleading expectations, and increasingly absurd marketing. Tesla unveiled the second-generation Roadster in 2017, took customer deposits, and promised deliveries in 2020. Six years past that deadline, it still hasn't delivered the car. Instead, it's demonstrating an even more outrageous version with features that will likely never make it into production. The original 2nd gen Roadster would still be an amazing car today. Why not just deliver what was promised? Then there's Full Self-Driving. Tesla marketed the idea that Model 3 owners could turn their cars into income-generating robotaxis. That never materialized. Even if the technology eventually gets there, the opportunity has already passed for many early buyers. Timing matters. Delivering something a decade late isn't fulfilling the promise you sold to customers. And then there's Solar Roof. Unveiled in 2016 as a revolutionary approach to residential solar, it struggled with costs, installation challenges, and adoption far below expectations. After nearly a decade, Tesla discontinued it entirely in August 2026. Another grand vision abandoned, leaving existing customers with a discontinued product to maintain. Then came the Cybertruck, marketed as a nearly indestructible, revolutionary truck. Instead, we got a vehicle with questionable build quality, numerous recalls, expensive repairs, disappointing results in several real-world off-road tests, and specifications that fell short of the original promises. It literally looks like a dumpster, but aesthetics aside, the collapsing demand speaks volumes about the reality of what Tesla delivered. Another heavily hyped product that fell dramatically short of expectations. This is how consumer trust erodes. Not through one disappointment, but through years of accumulating them. And this is part of the reason why many people who were once enthusiastic about Tesla have become critical and cynical about it. But there's something even more fundamental here: Tesla has completely departed from the grounded, practical vision that made so many of us enthusiastic about the company in the first place. Electric cars were ambitious, but the idea was grounded in reality. People could charge at home, infrastructure could gradually expand, technology could improve, and millions of ordinary people could eventually benefit. There was a realistic path toward mass adoption. What the hell does a flying Roadster powered by compressed-air thrusters have to do with any of that? It's an expensive, impractical engineering stunt with enormous packaging, safety, and regulatory challenges, and no credible near-term path toward mass-market usefulness. Modern electric cars already achieve ridiculous acceleration without this nonsense. What practical problem does it solve? Who actually needs it? When will ordinary consumers benefit? And watching Tesla fans compare this experimental prototype in a Roadster-shaped shell to actual production vehicles people can buy today is ridiculous. What's especially infuriating is the cult-like mentality surrounding all of this. You can't point out the history of failed promises, question the practicality, or demand realistic timelines without being accused of being a "hater" or having "Elon derangement syndrome." Tesla deserves recognition for helping make electric cars a reality, but that success doesn't give it a blank check to keep marketing increasingly fantastical promises while failing to deliver on previous commitments. This isn't hatred. It's disappointment from people who once believed in the company, watched it accomplish extraordinary things, and have since watched it increasingly substitute practical innovation with spectacle and promises. Elon fanboys are also ignoring a bigger pattern that goes beyond Tesla. What made many of us enthusiastic about Elon and Tesla and in the first place was a grounded vision of technological progress that could genuinely improve millions of lives. Electric cars were ambitious, but practical, achievable, and useful to ordinary people. Now we're supposed to get excited about flying cars with compressed-air thrusters that have no credible path to mass adoption and solve no meaningful problem for the average consumer. It's the same kind of thinking behind marketing the colonization of Mars as some urgent necessity for humanity's survival. There's nothing wrong with space exploration, but Earth isn't about to become uninhabitable because of the Sun. We're talking about geological timescales, while humanity faces enormous problems RIGHT NOW: poverty, hunger, access to education, corruption, abuse of power, wars, and a lack of government accountability. We have plenty of very real problems to solve before worrying about humanity's survival on another planet. And then there's DOGE. I was genuinely excited about the original idea of making government more efficient, reducing waste, and increasing accountability. Instead, we got questionable savings figures, inexperienced people making sweeping decisions, serious concerns over access to sensitive personal information, and an initiative that ultimately fizzled out without delivering its grand promises. Another enormous narrative that fell apart when confronted with reality. That's what makes all of this so frustrating. It's not that we stopped believing in technological progress. It's that we've watched someone who once pursued grounded, transformative ideas increasingly embrace fantastical promises, political spectacle, and questionable narratives disconnected from practical reality. And somehow, pointing out this history of disappointment gets you labeled a "hater" or accused of having "Elon derangement syndrome." The problem isn't dreaming big. It's repeatedly selling people those dreams, failing to deliver, and then expecting everyone to applaud the next, even more ridiculous promise without asking what happened to the last one. The world doesn't need more spectacular promises. It needs practical solutions to real problems, honest expectations, and accountability for what was promised. That's what made Tesla exciting in the first place, and that's what so many of us feel has been betrayed.

🇨🇭🇩🇪 German manufacturing is undergoing a structural crisis, and credible identification of its causes clearly requires rigorous research. Yet my advice to fellow researchers remains the same, namely to study 🇨🇭 in depth, since, as the chart suggests, it offers an excellent counterfactual. Why is nobody studying the stellar performance of Swiss industry?

Very well written. Indeed, learning 3D Printing requires a lot of knowledge and trial and error. Therefore participants love our workshops / trainings in Switzerland for learning the whole process from ideation to getting repeatable high quality results. hancon.ch/schulungenworkshop…
3d printing becomes a lot more interesting once you stop thinking about what you can print and start thinking about what material the part actually needs. pla, petg, nylon and flexible resin might all produce something that looks similar, but mechanically they’re very different. pla is stiff, easy to print and excellent for prototypes. petg offers better toughness and layer adhesion, making it useful for functional parts. nylon brings wear resistance, toughness and good fatigue performance, which is why it appears in gears, hinges and moving mechanisms. flexible resin allows complex, compliant geometries, but its durability depends heavily on the formulation and curing process. the interesting part is that material selection is only half the problem. print orientation, layer adhesion, wall thickness, infill, moisture, temperature and loading direction can completely change how a part behaves. a perfectly designed bracket can fail because the load pulls its layers apart. a nylon gear can perform poorly because the filament absorbed moisture before printing. a flexible part can lose its properties because the wrong resin or curing process was used. the same geometry, printed with different materials and parameters, can behave like an entirely different mechanical component. this is why i think every engineer should learn additive manufacturing. you’re not just learning to operate a machine. you’re learning materials science, mechanical design, manufacturing constraints and failure analysis through direct experimentation. print a part, load it, break it, understand why it failed, change the design and repeat. the real value of owning a 3d printer isn’t producing plastic objects. it’s having a small manufacturing laboratory on your desk where you can turn engineering assumptions into physical evidence.

もう二度と更新しねえけど、軽量化しといた。 Rust製のオープンソース3D CAD「SolidCraft」触ってたらボトルネックが気になりすぎて、気付いたら一人で勝手に限界まで高速化してた。 STEPリーダーの不要コピー撲滅して、穴あけ処理4.1倍速にして、バイナリも35%削って、ついでにUIも日本語化。 完全に自分用チューニングだけど、各OSのバイナリ置いといたのでCAD触る人はどうぞ。 github.com/sahenjp/solidcraf…
もう、3D CADに高いライセンス料金を払う時代終わりました。。。。 企業は別として、個人はもうこれで十分。 Rust製Auto CADクローン【SolidCraft】 わしらが求めてたのはこれや。 添付している画像は、SolidCraftのMCPでAIがポン出ししてきたスマホ&ペン立てや。 デモなのでQualityは許して。 SolidCraftはほんまに我々が求めてた全てが揃ってるわ!!! Rustによる信じられない軽量さ。 3DCADといえば、バカみたいにメモリを食うことでおなじみですが、めちゃくちゃ軽い。その点に関しては、普通に有料ソフトを上回ってる。 ほんで、いきなり日本語対応。神。 MCP対応でAIネイティブ対応。神。 CLI対応で制作を自動化できる。神。 STL・3MF・STEPなどの書き出しに対応。神 AIから、スケッチ、立体化、寸法変更、画面確認、書き出しまで直接操作できる。 「こういう物が欲しい」を会話から形にしていける。 Vibe 3D Cad. No more 時間泥棒。 CLI行けるってことはJSONのコマンドスクリプトも使えるから、寸法違いの試作や、計測・書き出しをまとめて処理する仕組みまで組める。 主要な3DCAD形式にも対応してるから、作った形をスライサーや別のCADに渡せる。 殆どの3Dプリンターにもそのままデータ渡せる。 まだ開発初期で、2D図面やCAMなど未対応の領域はある。それでも、個人の小物やケースの試作をAIと会話しながら進められるのは、めちゃくちゃ大きい。 昔、SOLIDWORKSのライセンス料金聞いて横転したのが懐かしいわ… リプライにGitHubリポジトリ貼っとくから、皆さんもぜひ試してくれや。 @bherbruckx Thank you for releasing this fantastic open-source CAD software with native AI support! Japanese support out of the box was a wonderful surprise. Much love from Japan!

実際に生成AIで3DCADが作れるか試しみたら、できちゃいました!スケッチから立体を作成して、後からパラメータを変更することもできます。STEPの入出力にも対応してもらいました。生成AIはClaudeを使用、カーネルはNVDIAのを使っています。数回のプロンプトで作成でき、1時間程度でここまで作ってくれました。これを販売提供するとかではなく、デモ用として作成したものです。それにしても時代は変わっていきそうですね。※動画は2倍速です。

In the past 24 hours... 1. We found out that data centers are bot farms 2. Bot farms play a direct role in changing public opinion and changing elections 3. Billionaires desperately support and want data centers I think it's safe to say that billionaires are the catalyst for the far-right rise we've seen globally...

For those curious what all the hype is about: Nvidias new open source CAD Kernel enables AI to design iPhone like curvatures! You can try it out in flux.ai today!
Over the next 2-3 years, mechanical engineers will learn how to augment their work with AI. The bulk of drawings and modeling will be done by AI with details added and nuances checked by a human. Large assemblies that today take a month to build in CAD will be reduced to a week within the next 12 months. The pace or ME’s work in just 12 short months will be staggering.

I’ve done a lot of public speaking, and hundreds of TV hits. Sometimes I’m really not that good. It happens – every once in a while, you just throw up a brick. But after watching this, I feel really good about myself. This was spectacular in its awfulness. Trump must’ve blown a gasket. I actually felt bad for her. She’s totally unqualified and probably a complete loon based on her background, but this was actually tough to watch if you care about the respect and honor of the United States. Now if you love, SNL or South Park – this is money.
It can’t be real. It’s something from Tina Fey’s imagination.

With everyone busily using LLMs + Blender/Three.js to make 3D models, I thought I'd try a different geometric representation. This dragon isn't a mesh, NeRF, 3DGS, or video model: it's 27kb of GLSL code (generated via LLM), defining a closed-form implicit surface. 🧵 [1/n]
