deepseek overthinking hasn't been fixed at all model is fast but it keep over thinking and ends up taking long time opus 5 took 80 minutes and i wasn't able to scroll site at all i could have asked it to fix it but it was one shot test for both models here's prompt: create a website for frontend devloper morden and stunning creative should have 3d models ,parallax scrolling and lenis scrolling effects and much more and smoother user interface experience use advance tech stack and write code i dont know what you do but i want that test yourself and share outputs if you can
Claude cooked by chinese model 😂😂😂😂
yeah it's weird how Claude models are super slow
Flash modle mogged Opus 💀
imagine 20 vs 0.2 no comparison bro .. v4.1 flash is just different .. too good.
Haha yess
the quality and cost efficiency of v4.1 flash is so impressive legend
nothing can beat cheap and better model
👀 DeepSeek mog?
I like what opus made but it didn't made anything to let me scroll in 80 minutes
I liked the one on the left; the fonts look more interesting
In the span of a week, OpenAI and DeepSeek are driving down Anthropic's IPO valuation by 30% to 50%.
😭😭😭
Opus 5🫠🫠🫠
what is wrong with opusies
didn't expected new DeepSeek model today
it was out few days ago already
More complex tests are needed to understand the capabilities of DeepSeek v4.1 Flash
running those 3d one for sure so let's see what it could do
$20’ for this???
yeah
If the final output was equally good, V4.1 Flash wins easily..... 100× cheaper and faster
I'd choose v4.1 anytime, it's efficient and cost effective
Chinese models are going crazy rn
DeepSeek is looking really good for its pricing. Ig I should give it a try 😸
Flash wins
that $20 vs $0.20 is the whole story. even if quality was tied, finishing 20 mins faster for 100x cheaper is a brutal flex for flash
Deepseek
what about astra?
Can I use it on work projects though? Or will they sell all my sensitive data?
Flash model that costs absolutely nothing destroyed opus that costs 2 kindneys to run and takes 15 years to do it
Wow 🔥🔥🔥
the metric is cost to accepted patch, not cost to first render. set the same scroll, responsiveness, and style checks, then let each model iterate until it passes. production routing starts there.
Opus 5🫡
Deepseeks first multimodal model really showing of wow!
Ran a similar Opus vs smaller-model bakeoff on a frontend ticket. Fast-and-cheap still blew the design system; slow-and-pricey respected the tokens. I now score on "matches existing CSS vars" first, not wall-clock.
![DeepSeek V4.1 Flash vs Gemini 3.8 Flash at 3D geometry test: six self-contained three.js stereometry scenes — a (3,8) torus knot, a Klein bottle, a great stellated dodecahedron, a hyperboloid ruled by 120 straight rods, a level-3 Menger sponge, a thick Möbius strip. one shot each, no libraries beyond three.js, every surface painted with a live iridescent rainbow that has to crawl across the geometry. cost: Gemini 3.8 Flash — $0.11 DeepSeek V4.1 Flash — $0.27 • gemini delivers all six figures for 2.4× less — 21k output tokens against deepseek's 168k • gemini is 5× faster — every scene under 25 seconds, deepseek took up to 3 minutes on the Möbius strip • deepseek wins the torus knot: its rope is vivid and glossy, while gemini rendered the same knot nearly black • neither model can build a real Klein bottle. both hand back a twisted tube and call it done try both on aimlapi[.]com](https://image.24vids.com/tw-2098056487465578894/amplify_video_thumb/2098055082444988421/img/BYUIgYB7mmUyE26F.jpg)
