Pencil just crossed 100,000 users! Today we are introducing SWARM mode. A team of AI design agents working with you in parallel. Your autonomous design agency. Download now.

@BottleCapAI @JaroslavBeck 🤯 cooked hard

300k downloads of our ThinkingCap model quant version in 2 days!!! 🤗 🙏

@josefprusa 👀👀

Qwen3.6-27B with 50% less thinking tokens on average, and over 90% less in best cases with ThinkingCap! I made an INT4 AutoRound quant tuned for a single RTX 5090: 2x262k ctx in vLLM, TQ4 KV cache, MTP on, Hermes Agent-tested. v2 w/ heavier calibration is next. Shoutout to @bottlecapai and @jaroslavbeck, my friends and neighbors across the river in Prague! Also: @UnslothAI, would love to see your quants too 👀 huggingface.co/josefprusa/Thi…

@JaroslavBeck 🏎️ love it!

Today we’re announcing our “ThinkingCap” efficient model series with a 2× thinking token reduction on average in Qwen 3.6 27B, with up to 10x faster generation on individual examples.

@Dev4YM @jaroslavurban @pencildev yeah, and you can now use all of these models natively in @pencildev on canvas

@tomkrcha @jaroslavurban @pencildev Damn lol

Opus 4.8 vs Minimax M3 designs in @pencildev guess which one is which? 🤷‍♂️

@sound4movement @pencildev Love it!

This past weekend, I asked Codex to teach me @pencildev from @tomkrcha, here is how it described this beautiful piece of software visually:

@chrislaupama @cursor_ai @pencildev @OpenAI 🫡

The holy trinity @cursor_ai @pencildev @OpenAI (Codex)

@jaroslavurban @pencildev Minimax on the left, Opus on the right,

@tomkrcha @pencildev Opus is left one.

@larz @pencildev Opus on the right, Minimax on the left

@pencildev full designs

@theo composer 2.5 kinda feels like that tho.

Remember the days where we used GPT-5 and Sonnet 4 on $20/month plans and it felt nearly unlimited?

Playing with Fable, remembering Opus. Life is life. youtube.com/watch?v=rQSmfR…

HeroUI is now available on @pencildev! 🚀 Build with HeroUI design system directly inside Pencil’s AI-powered canvas

@e_cdalton When you longboard, you rarely fall off the board esp. when the waves are clean. Also you can surf 3-4 months a year without a wetsuit from July to mid October, granted, having a jacket helps, but certainly there are like 2 months that you can do without it.

Watching "Endless Summer." The opening scene is in Malibu where almost no surfers are wearing wetsuits. The water was about the same temperature as it is today, when everyone wears wetsuits. What's going on? Thyroid function? More exposure to temperature extremes, less AC?

@reactorworld @lightspeedvp @AmplifyPartners @wndrco @Sky9Capital @FPVventures Let's goooo!

Today Reactor is coming out of stealth. We’ve raised $59M in Seed and Series A funding, led by @lightspeedvp, with participation from @AmplifyPartners, @wndrco, @Sky9Capital, and @FPVventures. Reactor is the platform for building in the World Model era: the infrastructure that lets developers build with them at global scale for the first time. Stream from a frontier World Model to your app, in real time, all in under 10 lines of code. World Models represent the next major shift in AI: pixels, audio and actions are generated on the fly, in real-time, in response to user inputs, and to the environment. Every time computing has made a shift from passive to interactive, entire industries appeared that didn't exist before. We're standing in front of such moment again. Over the last 6 months, we’ve assembled an all-star team with alumni from Apple, Meta, Google, Luma AI, Netflix, and Replicate. We're already partnering with some of the biggest names and labs in the world, and hundreds of developers are already building on Reactor. The World Model era starts now.

@reachdiego Yep. In the editor mode.

@tomkrcha Tom, this does not work in Cursor's agent window am I wrong? You have to be in the editor

Pencil just crossed 1M downloads on Cursor Extensions marketplace. With Composer 2.5, it's a killer AI design combo. Just flies. Designs a full website for desktop and mobile sub-minute. Fully editable on canvas inside Cursor. Video at 1x speed.

@NetRozee Which model are you after btw? There are many ways. But this should work via MCP

@tomkrcha i got so confused trying to install it on my opencode in WSL, previously i could do it at the project level

Grab Pencil for Cursor, infinite design canvas that uses your Cursor subscription. pencil.dev/downloads

Composer 2.5 (fast) vs Opus 4.7 (medium effort). Composer is about twice as fast in this case, sometimes even faster. Quality comparable in this case.
