I asked Opus 5.5 to explain camera focus by building an interactive lens lab Here's what it came up with after 1 hour 26 minutes in one shot, $25.66 API cost Move the focus ring and you can see the glass elements shift the sharp plane through the scene

build an interactive lens lab that shows how camera focus works, all in one html file that runs in the browser. when i turn the focus ring, the glass parts inside the lens should slide and move the sharp plane through a 3d scene. go all out.

opus 5.5 is f*cking cracked at motion design this entire video is code, 0 after effects im open sourcing the prompt template for these motion designs steal it to recreate these ↓ <inputs> Ask me for: 8 to 12 UI states I want the shape to become (e.g. button, loader, player, slider, toggle, tabs, chart, command palette, toast), pure black and white or one accent color, and a royalty-free song around 120 BPM (e.g. Mixkit, free for commercial use). </inputs> <direction> Dribbble-level UI motion. One shape, never cut: every state is the same element morphing its size, radius and color while its content swaps with a short blur. A cursor drives every change with real clicks and drags. Light warm-gray canvas, black and white components, one clean UI font (Geist). Springs everywhere, a tiny overshoot at most. The camera zooms so each state fills the frame. The last frame is the first frame, so it loops. Banned: bouncy easing, particle bursts, glows, gradients on UI chrome, mismatched icon strokes, dead time, anything that looks like a template. </direction> <structure> 120 BPM, 7 bars, something happens on every beat. Button → loader → check → dynamic island → music player with a play/pause morph → scrub the progress bar → it becomes a volume slider that stretches when dragged past max → a toggle flips on the beat → the knob becomes a liquid tab indicator → the tabs open into a chart that draws itself, with a tooltip on hover → it collapses into ⌘K → type to filter → enter → toast → back to the button. </structure> <build> 1. One HTML file, square 1440x1440. Every style is computed from time inside seek(t): no CSS transitions, no timers, no state carried between frames. 2. Springs are closed-form step responses. A value that changes target many times is the sum of one spring per change, so it stays a pure function of time. 3. The tab indicator's two edges ride different springs, so the leading edge stretches ahead of the trailing one. Same trick for the toggle knob. 4. Drags are direct manipulation: while the cursor is held, the value is computed from its position. On release it springs back from wherever it was. 5. Analyze the song with numpy for the beat grid and start on a downbeat. Place every UI sound by its measured peak. 6. Render with Playwright: 4 subframes per frame, blended with ffmpeg tmix for motion blur at 60fps. 7. Render one frame per beat before the full render. Fix anything off the grid, cramped or hard to read. </build> <gotchas> Never put will-change on anything the camera scales or the text renders blurry. Text that swaps inside a morphing container needs its own enter and exit timing or it overlaps. Make the last frame identical to the first, cursor position and speed included, or the loop stutters. </gotchas> <start> Ask me for the inputs, then show me the state list on the beat grid before you write any code. </start>

Ask me for: 8 to 12 UI states I want the shape to become (e.g. button, loader, player, slider, toggle, tabs, chart, command palette, toast), pure black and white or one accent color, and a royalty-free song around 120 BPM. Dribbble-level UI motion. One shape, never cut: every state is the same element morphing its size, radius and color while its content swaps with a short blur. A cursor drives every change with real clicks and drags. Light warm-gray canvas, black and white components, one clean UI font (Geist). Springs everywhere, a tiny overshoot at most. The camera zooms so each state fills the frame. The last frame is the first frame.

AGENT WARS We asked 5 top AI models to design, engineer and 3D print a bridge to with the goal of holding the most possible weight. 🇺🇸 Anthropic: Claude Opus 5.5 (High) 🇨🇳 Kimi: Kimi K3 (High) 🇺🇸 Meta: Muse Spark 1.3 (High) 🇺🇸 OpenAI: GPT 6 Astra (High) 🇺🇸 SpaceXAI: Grok 4.7 (High) Each bridge had specific parameters. It had to span 2 feet, use a maximum 500 grams of filament, and it had to be under 18 hours of printing time. We specified what type of weight and where we would place it on the bridge. The Score: • Claude Opus 5.5 held an estimated 130 lbs! It took 9 hours and 11 minutes to print 17 parts and used 441 grams of filament. • Meta Muse Spark 1.3 held 26.5 lbs. It took 13 hours and 12 minutes to print 49 parts and used 478 grams of filament. • OpenAI GPT-6 Astra held an estimated 17.5 lbs. It took 15 hours and 44 minutes to print 29 parts and used 442 grams of filament. • SpaceXAI Grok 4.7 did not finish. On assembly it could not stand up by itself. It took 12 hours and 22 minutes to print 29 parts and used 460 grams of filament. • Kimi K3 did not finish. It wasn’t engineered correctly so the bridge could not even be assembled. It took 11 hours and 19 minutes to print 35 parts and used 446 grams of filament. That means our champion for this episode is Claude Opus 5.5. Not only did it hold the most weight (by FAR) it also took the least time to print, used the least amount of parts and used the least amount of filament. This was episode 02 of Agent Wars, stay tuned for episode 03.

design a 3D printable bridge that spans 2 feet and holds the most weight. use at most 500 grams of filament and under 18 hours of print time, split into parts that fit a normal printer. the load hangs at the center. give me OpenSCAD files and build steps.

Opus 5.5 is next level. I’m genuinely impressed by the three.js details. I generated a playable boat scene through Japanese landscapes with dynamic weather, day and night lighting, realistic textures and 3D characters. Live site: The water reflections, physics, scenery and architecture are insane. I could look at this all day.

Ever wonder what $1874.40 of Opus 5.5 tokens looks like? Wonder no more. I highly recommend watching the whole video on 1080p on a large screen with sound on. Pay attention to all the little details. - Birds flying and diving into the ocean. - Cloth, signs and lights swaying in the wind. - Crabs scuttling along the shore and burrowing when you get close. - Fish swimming alongside the whale. - Lights illuminating the dock at night Then zoom out and see the entire island. Never dipping below 60 FPS at 1440p resolution. Yes, there's a few bugs and visual artifacts, some textures need improving, the shorelines waves sometimes look funny, but these are so trivial to fix at this point. FYI I'm on the $200 subscription plan. This used 59% of my weekly usage and took 2h 7h of API time using multiple subagents, about 8h in real-time. There was extremely little technical direction here. 99% of my prompts were "Add X and Y" or "This looks weird, make it better". It's a great time for hobbyists, bad time for professionals. This experiment has further cemented my view that technical creatives are about to experience a massive disruption.

build a big 3D island world that runs in the browser at 60 fps. fill it with living details: birds diving into the sea, crabs that dig in when you get close, fish swimming by a whale, cloth swaying in the wind, dock lights at night. go all out.

I used Opus 5.5 to formally verify the Claude Agent SDK using Lean. A couple short prompts = 16 PRs fixing various bugs and race conditions. Video attached. TLA+ also works well. I sometimes combine Lean and TLA+ to look for issues around data flow, concurrency, and state mgmt. I don't know either language well, but Claude is excellent at both. This approach is super useful for formally modeling your code and finding bugs that a human probably wouldn't have spotted. Is formal verification the future of coding (or at least, bug finding)?

use Lean to formally model this codebase and prove how it should work. use TLA+ too for the concurrency, data flow and state parts. find every bug and race condition the proofs turn up, then open a small PR to fix each one.

I ported the Omarchy screensaver engine (ttfx) from Rust to x86-64 assembler, and it's up to 17x faster!! One-shot translation by Opus 5.5. We keep drilling until the agentic drill bit hits bedrock!

port this rust terminal screensaver engine to pure x86-64 assembly for linux, raw syscalls, no libc. keep every effect looking exactly the same. then add a benchmark that runs both versions side by side and shows how much faster the asm one is. make it work in one shot.

for the past few months i've been asking our models to paint. opus 5.5 is very skilled at emulating different styles every image here is a python program generated pixel by pixel. there is no image model, and no off-the-shelf art software. instead, it's about 7,500 lines of code using standard libraries to emulate different brush styles. the agents don't use any pictures as reference, instead working only from what they know about each painter

write one python script that paints a picture pixel by pixel with only the standard library, no image models, no art tools, no reference pictures. pick a famous painter and copy their brush style from memory, like van gogh's thick swirly strokes. save it as a png. go all out.

Claude Opus 5.5 writes a fugue in the style of Bach. I called Astra’s fugue the most impressive musical feat I’d ever seen from an LLM, and this is just as good. The circle-of-fifths sequence beginning at 1:13 is beautiful. The interplay of voices is natural and satisfying. LLMs are getting to the point where their music is good enough to listen to for pure enjoyment.

In LilyPond (version 2.24), write a complete fugue for organ in the style of Bach.

Yesterday, my boys and I vibe coded a game together. They tell me what they want in their game and I prompt it into Opus 5.5 to build it. And of course they picked "Zelda Breath of the Wild" inspired game, where they can explore an open world, do dungeon puzzles, fight mini bosses and a final boss. The twist is that the hero holds a giant paintbrush as a weapon, each color had a different attack and effect (red = fire, blue = ice, yellow = bounce, green = vines). And oh they also wanted to fly on the paintbrush. We spent our whole saturday playing and iterating on the game. It was great fun. I told them, the future is all about Imagination, whatever they can imagine, it will be manifested in a digital experience. At the end of the day, the game had: - 2 biomes (1 island and a bunch of floating islands) - Paintbrush-based combat (4 colors representing different effects and mechanics) - 3 dungeons with puzzles - An undeground cave - Unlockable flying paintbrush when you activate 4 crystals around the island - 30+ enemies and elites - 1 giant boss As you can see in the gameplaye video below, its not the most polished video game but it's so satisfying to see my boys getting bewildered when whatever they asked for, the game is built before their eyes. Of all the games I have vibe coded so far, this was the most satisfying because my boys were actively co-creating it and playing it. This is definitely not the last game we're making together, they have already started brainstorming their next game, hint: "Peak with grappling hooks and TNTs." You can play the game here, works only on desktop:

make a 3d open world game in three.js, one html file, like breath of the wild. the hero fights with a giant paintbrush, red is fire, blue is ice, yellow bounces, green grows vines. fly on the brush to floating islands, plus dungeon puzzles, mini bosses and a final boss.

This is absolutely insane. I just built a fully seamless "No Man's Sky". With AAA-Graphics with 1 prompt. Using Opus 5.5 & @threejs on @TesanaAI The game has over 80 planets to seamlessly explore. Every planet has it's unique biome, minerals, aliens and weather system. You can leave the space ship and explore every planet freely. The flying and handling of the space craft feels just perfect. The video speeds up a bit to save you the time it takes to traverse the galaxy.

you have access to fal, eleven labs, blender, javascript and anything else you could possibly want, and have my permission to download any application if it helps you express yourself. token usage is not a concern. i want you to create a video that introduces you to the world. it is completely up to you. do not report back to me until you are finished

HOLY SHIT. OPUS 5.5 IS CRAZY. Napoleon's sharpest battle lasted a morning and won him Europe. I just had it turn that morning into a complete 5 minute film. All code. - It wrote the engine, the soldiers, the score, the voice. - The hills are the real battlefield from satellite data. - The sun rises where it actually rose on 2 December 1805. 90 minutes to build. 4 hours to render. $40 (cloud agent credits). Code + prompt below.

Create a 4 to 5 minute cinematic video about the Battle of Austerlitz (1805), built entirely in code. Research the battle thoroughly and decide for yourself how to tell the story. I want it to be historically accurate, dramatic, easy to understand, and visually exceptional, with scale, smoke, dramatic skies, cavalry, massed formations, and a sense of chaos. Don't make it feel like a generic infographic or strategy game. You have complete creative control. Surprise me.

Finally, Opus made me the perfect jelly - even better than Astra’s 🍉🤯 Claude Opus 5.5 vs ChatGPT-6 Astra This time, I prefer Opus: the juicy color, glossy flesh, and especially how the slice stretches, folds, and jiggles when you let go. It genuinely looks like gummy candy I want to touch Astra’s version is nice too, but Opus gets my vote here Estimated API cost: Opus - $4.50 Astra - $2.05 More than twice the price. Do you think it’s worth it? 👀

Create "Melon Jelly", a polished, interactive 3D watermelon jelly slice that runs directly in the browser using genuine WebGPU and WGSL shaders, in a single, self-contained HTML file. Make a thick, rounded wedge with translucent ruby-red jelly flesh, a glossy green striped rind and dark seeds, like an expensive gummy candy photographed in a studio. Use a volumetric soft-body simulation (tetrahedral mesh with XPBD) so the user can grab, stretch, bend and twist the slice, then release it and watch it wobble before gradually settling.

build a working computer from scratch, entirely in code, starting from individual logic gates. design the CPU, the memory, an assembler, a tiny operating system, and a game that runs on it. the game has to run on your gates, not in javascript pretending. visualize it in 3D so i can play the game, then zoom all the way down through the chips into the gates and watch the signals flow. go all out.

Opus 5.5 just filed a pull request that changes the streaming behavior in T3 code. It's so cool that I can send off a prompt with a vague idea of what I want, and the result is a ready-to-merge pull request with a video demo of the changes directly in the PR. The PRs I make with AI are significantly better than the ones I used to make by hand. The future is awesome.

change how streaming works in this app so new text shows up smooth as it comes in. then open a pull request that is ready to merge, and record a short video demo of the change and put it right in the PR.

Opus 5.5 ultracode is unreal. I just built the game I wanted most as a kid on PS2 — Dynasty Warriors — with Opus 5.5 ultracode. Zhao Yun vs 300 soldiers: combos, dodges, Musou. Halfway through I wanted it to go faster. Then I opened the preview link and just… stopped. Let it cook. Play it : Repo: stack:three.js

make a Dynasty Warriors style hack and slash game in three.js that runs in the browser. Zhao Yun with his spear fights 300 soldiers on screen at once, with combos, dodges, a big Musou attack and full character animations. make it feel smooth and huge. go all out.

Claude 5.5 is crazy good with animations. Following is one-shot journey from a single bacterium cell all the way to quantum fields constituting it. Awe-inspiring! (It chose to add an original score to it too!)

create a self contained aesthetically pleasing, breathtaking animation of a bacterial cell. it should start with cell and then zoom into it at multiple scales, going into DNA and then further into DNA as atoms and finally ending at quantum fields.

use javascript for it. be detailed and scientifically accurate. it should evoke awe.

ok here it is - my first Opus 5.5 vibecoded threejs 3D experience my God!! Opus is creative!! I made a road that forgets which way is down. It folds 90° up a yellow wall, runs upside down across a ceiling, and turns into sheet music: steer through the notes to play each street's melody. Watercolour. Ink. A radio on the roof. #vibejam

make a single html file three.js game where you drive a road that forgets which way is down. it folds 90 degrees up a yellow wall, runs upside down across a ceiling, then turns into sheet music where steering through notes plays a melody. watercolour and ink look, no assets.

I have a G4 iMac with a Mac Mini inside that I use as a server. I asked Claude Opus to recreate an almost pixel-perfect MacOS X 10.2 desktop with a Finder face and some widgets to monitor how everything is running. It gave it expressions based on CPU state, a pretty close genie effect, a PiP view of the real desktop and a sleep mode that turns on at night.

Opus 5.5 killed the game. We had it and GPT-6 Sol both draw Dario in Canva with ego (lite). Claude Opus 5.5: 1h 23m, $6.31 GPT-6 Sol: 26m, $14.97 Opus took 3x longer, cost less than half, and drew a much better Dario.

open Canva in the browser and draw a portrait of [famous person] from scratch using only the shapes, lines and draw tools. no uploaded photos. take your time, get the face, hair and glasses right so it really looks like him, and keep fixing it until it's good.

i asked opus 5.5 to make a 3 min video about the history of bitcoin i told claude to rely on data from my local 1.8 tb postgres database of bitcoin data (coins, blocks, hacks, attribution, everything) here’s what opus made in 1 hour 22 mins on max effort with a 10 line prompt

make me a 2-3 minute video about the history of bitcoin. rely on our bitcoin data in the postgres for key dates, prices, events, hacks, attribution, etc. use an original score using instruments from logic and garageband, and line up the score to the events in the scenes. brand it and use our colors.

Opus 5.5 is crazy, and this is yet another proof. 3 moves. That's all it needed to solve the Rubik's Cube and beat GPT-6 Sol, Jev and Laya, with the same limits for all four models: 20 moves or 5 minutes. Opus 5.5 solved it in 1m 12.87s with the perfect 3 moves. GPT-6 Sol made a wrong first move and ran out of time after 4. Jev and Laya both used all 20 moves without solving it.

here is a scrambled rubik's cube state. tell me only the next single move to solve it, in standard notation like R, U' or F2. you get 20 moves max and 5 minutes total, so think hard and find the shortest path.

I'm truly impressed with Opus 5.5. I asked it to visualise Atlantis in ThreeJS for me, and it created a tour around Poseidia, the last surviving island of Atlantis. Sound on 🔊 for full trailer experience. Even this trailer is made by Opus 5.5 as well. I think we’re on the verge of a new type of media: Generative Experiences. The idea is that you can describe a world you have in mind and step into it is pretty incredible. You could explore its cities, meet its inhabitants, discover its stories, and shape what happens next through your own choices. This took Opus 5.5 about two hours to make. But if we extrapolate a year into the future, I can imagine being able to conjure up these kinds of fantastical, immersive experiences within seconds. The possibilities go well beyond gaming. Writers could walk through the worlds they’re building. Children could explore an ancient civilisation and ask questions along the way. Learning could become an experience you actively participate in, with the world responding to what you’re curious about. This is incredibly exciting and I am here for it. You can tour around Poseidia here:

make a three.js scene in a single html file that shows atlantis. give me a cinematic camera tour around poseidia, the last surviving island, with temples, canals and tiny people, plus epic music and sound made with web audio. make it feel like a movie trailer.

Flew back into LAX last night and was frustrated by the traffic flow. Got me wondering how bad it is vs. the other top 4 US airports. So I had Opus 5.5 whip this up for me on the Uber ride home. LAX traffic flow design is truly a disaster.

make a single HTML file that shows animated car traffic flowing through the terminal roads at LAX and the other top 4 US airports, side by side. draw each road layout from above so you can see where cars back up, and show a jam score for each one.

The asset pipeline is becoming code. Willowmere was built with Claude Opus 5.5: • No PNGs • No 3D model files • No audio samples Every object is generated procedurally with Three.js, while the music and sound effects are synthesized in-browser through the Web Audio API. Game design still needs taste. But the production bottlenecks are disappearing fast.

make a cozy 3D exploration game called Willowmere in a single HTML file with three.js. no image files, no 3D models, no audio files. build every tree, house and object in code, and make the music and sound effects with the web audio api. make it look lovely.

Opus 5.5 destroyed GPT 6 Sol at Blender 3D Pelican 🦩 Both frontier models dropped today so we gave them the same brief to animate a looping 3D pelican on a bicycle in Blender and Opus 5.5 came back with the more charming ride Run both models via API ->

write a python script for blender that builds and animates a looping 3d pelican riding a bicycle. make the pedaling and wheels loop smoothly, and give the pelican a charming little bob and wing flap as it rides. use only built-in blender tools, no outside files.

Forget threejs demos, Opus 5.5 is *incredible* at building apps. This is Letters Abroad, a language-learning app I'm working on. You exchange letters with an AI pen pal, and learn a language through context (plus some brain science magic). (also built by Opus, of course) I've been tinkering with this the last week. I built a prototype with Astra, but wasn't happy with the design. Tried Fable, still wasn't good enough. Then Opus 5.5 dropped. In a few hours, I've made more progress on the visuals than in a week of burning tokens. This model is insane. It reads my mind and nails it every time. All the gorgeous 3D models and fluid transitions are thanks to Opus. Crazy idea, prompt, repeat. No more quota anxiety, just non-stop flow state. I'll be writing about my prompts/skills/learnings from building this. Lots to share; this generation of models is absolutely game-changing for design!

build a language learning app called Letters Abroad where you trade letters with a pen pal and pick up the language from context. tap any word to see what it means. make it gorgeous, with little 3D objects and smooth, fluid screen transitions. single HTML file.

Continuing the experiment: the most complex fully procedural world I can get out of three.js. Zero downloaded assets, sound included. This time the lead is Opus 5.5. One prompt + a reference image → a plan. Then I kicked off 3 plan steps by hand. Never asked it to fix anything. What you see is the first pass, zero correction rounds. 3h36m active · 445 requests · +5,010 lines · ~$60 at API pricing Reference in the replies 👇 #threejs #tsl

I asked Opus 5.5 to explain gravitational lensing by building an interactive black hole lab One prompt for the first version, then a dynamic workflow to polish it for three rounds while I slept. This is what I woke up to: 5h 28m end to end, $90 at API prices Drag the black hole and the sky behind it bends into arcs, closing into a full ring when everything lines up Each round ran 3 agents. Two reviewers each picked 9 to 10 issues and ranked them P0, P1, P2. The third one fixed them. Round 1: 3D materials and lighting + UI and type Round 2: camera motion and interaction + science-communication design Round 3: a design director deciding whether it ships + visual QA and performance Every P0 got fixed, the rest only if worth it. When the two reviewers disagreed, it picked one and wrote down why. It backed up before each round, checked screenshots after, and rolled back anything it couldn't fix.

build an interactive black hole lab that explains gravitational lensing, all in one html file with three.js. when i drag the black hole, the sky behind it should bend into arcs and close into a full ring when everything lines up. add short labels that teach the science. make it look stunning.

every launch video on the internet is a template now. left is @gojiberryai launch video. right is the version I had Opus 5.5 rebuild for my brand in 15 minutes. same motion, same cuts, playing in sync. I’m open sourcing the exact prompt + process so you can recreate any launch video on the internet. full prompt below ↓

TASK: frame-locked 1:1 remake of REF=[path/to/reference.mp4]. Swap ONLY: brand name→[NAME], logo→[path/to/logo.png|svg], palette→[hex list or "derive from logo"]. All else identical: layout, sizes, positions, timing, easing, camera, cuts, blur, cursor path, typing cadence, audio beat grid.
ACCEPTANCE: REF and remake stacked + frame-locked → same pose every frame. Cuts 0 frames off. Position/size error ≤1% of frame.
PHASE 0, ANALYSIS (no building yet): ffprobe fps/res/duration, extract ALL frames to ref/full/, detect cuts, write SPEC.md. MEASURE with numpy on ref frames, never eyeball.

I had 26 Opus 5.5 agents build a game overnight. It's a heist through five nested worlds, with go-karts on a giant's kitchen table, bots hunting you, and friends stealing your loot. Most vibe-coded games are demos. This one is different.. it's multiplayer and you can play it right now.

build a multiplayer heist game that runs in the browser on phone or computer. five nested worlds linked by portals, no loading screens, go-karts racing on a giant's kitchen table, bots hunting you, and friends can steal your loot. make it really playable, not a demo.
