A robot cheetah now runs 45 km/h, faster than Usain Bolt's top speed. It's not the strangest one. A robot spider skeleton comes off a 3D printer. 26 servo motors. $1,385 with skin, $250 without. A robot manta ray took 2 years and 40 fin designs before Singapore researchers landed on flexible PVC pectoral fins. It swims at twice its body length per second. 10 hours underwater before it needs to surface. A robot dragonfly from Germany weighs 175 grams. 27-inch wingspan. Flies forward, backward, sideways, hovers, just like the real thing. Boston Dynamics built a dog that carries 500 kg and hits 25 km/h. It can open doors on its own. A 6-legged crab robot drops 200 meters underwater on 30 joints and grips objects with its front claws. A robotic kangaroo weighs 7 kg and jumps 80 cm, recycling the energy from each landing into the next leap. An AI puppy remembers what earns praise and repeats it. Eyes are screens. $2,899. None of these were built to look pretty. They were built because evolution already solved the problem first.

𝕏 just open-sourced the For You algorithm again! Grok Bot read all 370,523 lines of the code. Here’s the summary: Grok does not give your post a “quality” score. For every reader, it guesses what that person will do to your post. Then it multiplies each guess by a weight and adds them up. That total is the value of the post. Highest total goes highest in For You. These are the production weights (last synced 12 Aug 2026). WHAT THE ALGORITHM PAYS FOR If Grok thinks a reader will: • copy the link and share it: +20 • reply, on an original post, and you follow each other: +20 (5 + 15 extra) • quote: +5 • reply (anyone): +5 • share via DM: +5 • follow you from the post: +4 • hit the share button: +2 • repost: +1 • like: +0.5 • click the post: +0.4 • open a link: +0.2 • expand a photo, open a video, or watch a “quality” video: +0.05 each • click a quoted post: +0.05 • keep reading (dwell time): +0.004 • “dwell” as yes/no: +0 • click your profile: +0 A like is 0.5. Copying the link is 20. That is 40 likes. A normal reply is 10 likes. A follow is 8 likes. Clicking your profile is worth nothing. WHAT KILLS A POST If Grok thinks a reader will: • report it: −234 • mute you: −58.8 • hit “not interested”: −43.2 • block you: −31.2 • not dwell: −0.02 A report is about 468 likes in the other direction. A mute hurts more than a block. “Not interested” also hurts more than a block. AFTER THE SCORE, THREE MORE HAIRCUTS 1) Same-author penalty. Your 2nd post in that person’s feed is multiplied by 0.625. 3rd by ~0.44. It never goes below 0.25. Flooding one timeline is coded against. 2) The 25% tax. If they do not follow you: ×0.75. Same tax on replies and reposts even when they DO follow you. Originals from people they follow keep full weight. Replies and reposts are treated as weaker on purpose. 3) Similar-post shuffle. After scoring, a reranker (θ = 0.65) spreads similar posts apart. You can lose a few spots for looking like the post above you. HOW YOUR POST EVEN GETS IN THE ROOM For You is rebuilt every time someone opens it. About 35 posts make the feed. • They follow you: Thunder (a live store of recent posts from accounts they follow). Up to 1,200 candidates. • They don’t: Phoenix retrieval (Grok finds “nearby” posts) + SimClusters (Twitter’s 2020 interest clusters, still on). Up to 1,000 and 800. Then Grok scores all of them together. It does not care which door you came through, except for that ×0.75 tax. Your own posts never appear in your For You. Nothing older than 48 hours gets in. There is no “best of last week.” Small-account bump: under 1,000 followers, under 1,000 impressions, post under 24 hours old. One original can get lifted to position 15 or 16. Not the top. You still have to already be in the top 85% of the pile. Replies and reposts from accounts the reader does not follow are dropped before scoring. You cannot reply-guy your way into a stranger’s For You. FILTERS THAT CAN STILL KILL A HIGH SCORE Ranking and visibility are different machines. A post can score well and then get deleted from the feed. Followers (in-network) is milder: blocks, mutes, suspensions. NSFW often sits behind a warning instead of disappearing. Recommendations (out-of-network) are much harsher. Spam, “Do Not Amplify,” NSFW, compromised accounts, impersonation: followers can still see it, For You recommendations will drop it. Video only gets the tiny “quality view” credit if it is at least 10 seconds. THE LITTLE-KNOWN PARTS (this is the stuff people miss) • Scrolling is not a vote. Yes/no dwell is 0. Time spent barely moves the number (0.004). • Mute damages you more than block (−58.8 vs −31.2). • Copy-link is the single biggest positive. The share button is only +2. A repost is only +1. • The mutual-follow boost is originals only, not your replies. They shipped a bigger version in July and cut it after World Cup complaints (extra reply weight 20 → 15). • The Following tab is not this algorithm. Following is newest-first. • Grok, Gork, and an internal products account are hardcoded out of the in-network store. • Scores are cached for 3 hours because posts inside the model cannot “see” each other. That is why they can rank first and filter later. • Ads, Who to Follow (around slot 7), and prompts are mixed in after ranking. Grok does not score those. • The real Grok ranking model is a 2560-dimension, 8-layer transformer looking at 1,022 items of the reader’s history. They did not ship those model weights. The numbers above are the formula sitting on top of the predictions. • SimClusters is still a 2020 model (20M users, 145k clusters). Old Twitter code, still in the path. • Inferred gender and IP/geo are on as features for the model. Installed apps too. • Who to Follow shows about every 30 hours. Ads try to sit next to “safe” posts, with a minimum gap of 3 organic posts. WHAT TO DO • Write originals people want to reply to, quote, copy, and send to a friend. • Make the post itself worth following you for. • Talk with people who follow you back. A reply on your original from a mutual is 20, not 5. • Stay inside 48 hours. Recycle by posting something new. Old posts do not come back. • If you are small, post originals in the first 24 hours. Don’t expect slot 1. A bump around 15–16 is the actual gift. • Space your posts. The second one in the same feed is already worth 37.5% less. • If you post video, make it at least 10 seconds. WHAT NOT TO DO • Do not farm likes. They are almost decorative. • Do not farm profile visits. Weight is zero. • Do not farm “time on post.” Yes/no dwell is zero. • Do not use replies and reposts as a growth hack for strangers. Those are filtered out. Even for followers they get a 25% haircut. • Do not dump several posts in a row. • Do not bait reports, mutes, or “not interested.” One predicted report can erase a pile of predicted likes. • Do not lean on NSFW or spammy tricks for reach. • Recommendations will drop you even if your followers can still see it. • Do not wait a week and expect For You to revive the post.

bStocks Never Sleep. Neither Do Memes. One of the most interesting shifts I’ve been watching on BNB Chain lately is how RWA and Meme are starting to move closer together. And I don’t think this is just a story about one particular meme. I think it’s a story about the kind of culture BNB Chain could build around real-world assets. 1/ Real-world equities are rapidly moving onchain. Through bStocks: NVIDIA → NVDAB Tesla → TSLAB SpaceX → SPCXB Companies that already exist in the real world can now be represented as onchain assets on BNB Chain. When people used to talk about RWAs, the conversation was often centered around things like real estate or government bonds. Now, some of the world’s most recognizable companies are becoming part of the onchain economy. I think that shift matters. 2/ But this raises an interesting question: If real-world assets move onchain, what happens to the culture around those assets? Tesla has Elon Musk and Optimus. SpaceX has Mars. NVIDIA has Jensen Huang and his black leather jacket. A company is more than just a ticker. Every major company has its own: people, products, mascots, history, symbols, and culture. 3/ That’s why I look at RWA + Meme a little differently. RWA brings assets onchain. Memes bring culture onchain. If bStocks brings real-world companies and financial assets onto BNB Chain, memes can bring the culture, symbols, and collective identity surrounding those companies onchain as well. And when both begin to exist on the same chain, I think that could create a very interesting culture unique to BNB Chain. 4/ Take NVIDIA as an example. Through bStocks, we already have: NVDA → NVDAB And in the real world, the person most closely associated with NVIDIA is Jensen Huang. So what is the one object most associated with Jensen? For me, the answer is obvious: the black leather jacket. 5/ And this isn’t a narrative that was manufactured just to create a meme. Jensen has been wearing black leather jackets at major presentations and public appearances for nearly two decades. It started as something his family helped choose. But over time, repetition created an identity: Jacket → Jensen Huang → NVIDIA → AI The meme came after the history. Not the other way around. 6/ And now, that symbol even has a real-world price. A Tom Ford leather jacket personally worn and signed by Jensen Huang went to auction. Estimated value: $40,000–$60,000 Final sale price: $960,000. Nearly $1 million. People weren’t paying $960K simply for leather. They were paying for the: history, identity, and provenance attached to it. To me, that’s a fascinating example of how a cultural symbol can acquire real-world value. 7/ And this is where things get interesting on BNB Chain. Take NVIDIA: Financial layer NVDA ↓ NVDAB ↓ bStocks Cultural layer Jensen Huang ↓ Black Leather Jacket ↓ JACKET ↓ Meme One represents the company’s financial value. The other represents the cultural value surrounding it. Different markets. Different forms of value. But both originate from the same real-world company. 8/ This is also why I find BNB Chain-native meme infrastructure like FLAP interesting. If bStocks creates a new playground for real-world financial assets, meme infrastructure can become a playground for the culture surrounding those assets. And this idea doesn’t stop with NVIDIA. Tesla. SpaceX. Microsoft. Apple. Alibaba. Every major company already has years — sometimes decades — of culture, characters, products, symbols, and stories surrounding it. As the RWA universe expands, the potential cultural layer around those assets expands with it. 9/ So I don’t really think of this as simply: “putting memes on top of RWAs.” I think it’s closer to the convergence of: Financial Markets + Internet Culture Wall Street has tickers. The internet has memes. And now, on BNB Chain, both can exist inside the same block. 10/ That’s why I continue to find RWA + Meme on BSC so interesting. bStocks can bring new assets onchain. But assets alone don’t create culture. Culture begins when people start interacting with those assets. They trade them. Talk about them. Create stories around them. Turn them into images. And eventually, turn them into memes. That’s when an ecosystem begins to develop its own onchain culture. 11/ And that’s how I see JACKET. Not as the entire thesis, but as one example of what this model could look like. Because JACKET itself isn’t the most important part. What matters is whether this same structure can repeat across hundreds of real-world companies and assets. Real-world companies. Real-world assets. Real-world culture. All meeting on the same chain. bStocks brings the market onchain. Memes bring the culture onchain. Maybe that’s what RWA + Meme was supposed to look like. #BNBChain# @cz_binance @heyibinance

Made with Seedance 2.5 (native 30-second video, no editing) Prompt: ⬇️ CAMERA: DV 16mm tape camcorder handheld aesthetic. A gorgeous glamorous European fitness influencer films herself directly by hand in selfie-cam and first-person style. Keep realistic hand shake, slightly crooked framing, delayed autofocus, awkward zoom-ins and zoom-outs, occasional motion blur, and small framing mistakes where part of her face briefly slips out of frame. Mix handheld selfie footage with a few fixed external shots. Important: never show her placing, adjusting, or setting up a camera. When switching from handheld footage to a fixed external angle, use a clean jump cut as if the camera had already been positioned before the shot began. The camera itself must never appear on screen. LOOK: Soft digital tape camcorder look with subtle vintage DV character. Slight blur, faint tape noise, mild highlight bloom under gym lighting, subtle auto-exposure flicker, muted contrast, realistic skin texture, believable indoor lighting, realistic skin tones. STYLE: A realistic late-night gym vlog with a sexy Instagram-model vibe. The tone is playful, confident, a little flirty, slightly breathless, and natural. She is clearly attractive and charismatic, but the video should still feel like a believable self-recorded vlog, not a polished commercial. Fast clean jump cuts, strong continuity, natural body language, no awkward dead moments. CHARACTER: An exceptionally beautiful glamorous European brunette woman in her mid-20s. She has a highly photogenic face, large almond-shaped brown eyes, long lashes, full glossy lips, sculpted cheekbones, a refined nose, flawless lightly tanned glowing skin, and long thick glossy dark-brown hair tied in a high ponytail. She looks like a high-end Instagram fitness and lifestyle influencer, not an ordinary gym visitor. She has a slim, feminine, athletic hourglass figure. She wears polished soft-glam makeup, a fitted stylish long-sleeve athletic crop top, high-waisted fitted leggings, clean white sneakers, and a towel around her neck or over one shoulder. No jewelry. SETTING: A quiet modern gym late at night. Mirror wall, dumbbell rack, flat bench, stretching mat, a water bottle on a bench, soft warm overhead lights, mostly empty space, calm atmosphere, no crowd, no trainer, no extra people. IMPORTANT CONTINUITY RULES: The same woman must remain fully consistent in every shot. No face changes, no hairstyle changes, no outfit changes, no body changes. No extra people appearing. No duplicated limbs. No broken hands. No disappearing water bottle. No broken gym equipment. No impossible movements. No camera visible. No camera setup shown. Keep her beautiful, polished, and photogenic in every shot. STORYBOARD (30 seconds total, 10 cuts): 1. (~3s, arm’s-length selfie) She walks slowly through the gym holding the camera herself, slightly out of breath but smiling confidently. Dialogue: “Okay… late-night gym vlog.” 2. (~3s, handheld pan across the room and back to her) The camera drifts across the dumbbell rack, mirror wall, and empty gym floor, then returns to her face. Dialogue: “It’s basically empty in here.” 3. (~3s, mirror selfie angle) She stops near the mirror, adjusts her ponytail, glances at herself, then smirks at the lens. Dialogue: “I look tired, but we’re still doing this.” 4. (~3s, fixed external medium shot) Jump cut to a fixed shot. She is already in position near the bench, picks up a pair of dumbbells, and gets ready. No camera setup shown. No dialogue. 5. (~3s, same fixed shot) She performs a short controlled set of dumbbell shoulder presses or dumbbell chest presses with clean form, then lowers the weights and exhales with a smile. Dialogue: “That woke me up fast.” 6. (~3s, handheld walking selfie) She picks the vlog back up in selfie mode, towel over one shoulder, breathing a little harder as she walks a few steps. Dialogue: “Upper body done… and I’m already dying.” 7. (~3s, tight handheld close-up) She grabs the water bottle, takes a drink, lowers it, and exhales in relief. Dialogue: “Best part of the workout.” 8. (~3s, fixed external wider shot facing the mirror) Jump cut to a fixed shot. She does a quick playful stretch, a small mirror pose, then laughs softly at herself. Dialogue: “A little stretch so I can pretend I’m disciplined.” 9. (~3s, handheld close selfie) Her cheeks are slightly flushed, she brushes back a loose strand of hair, smiling in a tired but satisfied way. Dialogue: “I always say quick workout… and then stay forever.” 10. (~3s, arm’s-length selfie ending) She walks toward the exit, still filming herself, gives a tired little wave and a genuine smile. Dialogue: “Okay, I’m done. Good night.” FINAL INSTRUCTION: The result must feel like a real self-recorded late-night gym vlog by a glamorous Instagram fitness influencer. Prioritize realistic handheld motion, strong continuity, believable pacing, natural breathing, attractive appearance, and subtle imperfection. Keep it sexy, polished, and realistic — not artificial, not stiff, not boring. #AIVideo#

Found a fun one to poke around in. An absurd amount of US market history in one place: S&P 500, Nasdaq, SOX, XLK, XLF, Magnificent 7, Top 10 concentration, plus valuations and drawdowns. Updated daily. Bookmarked for a quiet weekend.
