@dreamchyzw @Maxq5xs Thanks for trying Carbon on Tabbit and sharing your experience! Glad it solved your problem. We've passed your feedback on usage limits to the team.

[Tabbit @TabbitBrowser]

We taught AI to click like a human. Then it learned to code instead.
Interestingly, the @browser_use team arrived at the same place this year. They lean toward raw CDP; we chose Playwright, the framework models already know best. Different trade-offs, same direction: let the model drive the browser through code.

This is a full record earned through real engineering blood and tears, through countless late nights of tearing everything down and starting over, and through benchmark after benchmark beaten. https://t.co/6jw0Dd2TcV

@Google @GoogleDeepMind We put Gemini 4 Carbon and Claude Opus 5.5 head-to-head on Chinese writing in Tabbit.

Same prompt, side-by-side outputs below.

Gemini 4 Carbon is now live in Tabbit, free for every user. Time to create your masterpiece!

目前哪家模型中文表达能力最好？
Gemini 和 Claude 应该是目前公认的中文写作能力最强的两家模型（国内可能再加上 Kimi）
正好最近 Gemni 4 Carbon 上线了 Tabbit，本人平常会用 Tabbit 看网页写稿子，致力产出美味粮食😋
我拿 Tabbit 里的 Gemini 4 Carbon 和 Claude Opus 5.5 各进行了记叙文与议论文写作的对比。个人主观评价是 Carbon 秒了 Opus，以及如果当初高考语文作文有 Carbon 估计轻松满分。全文放在评论区

附上 EssayBench 评分：

We asked Claude Fable 5.2 and GPT-6 Astra to draw Buddy in Canva using Tabbit CLI.

GPT-6 Astra: 8m 54s · $3.94
Claude Fable 5.2: 6m 35s · $2.83
Both on high reasoning, no fast mode. Costs estimated at API rates (USD).

Which one would Buddy hire? 🦄

[Tabbit @TabbitBrowser]

@evvvvince The gaps are surprisingly close! Claude actually used ~10% more tokens overall, though. Most tokens were cached, and Astra’s cache-read rate was 5× higher in our estimate.

@RaveyFok Thanks for flagging this! We’ve shared it with the team.

Tabbit Model Chart Vol. 11

Hy4 debuts at #11. Gemini-4-Argon stays ahead of Sonnet 5.5 and holds #1. The top five remain unchanged, which points to strong use-case stickiness.

We've received a lot of user feedback asking whether deep thinking can be adjusted or turned off. To meet different needs, Tabbit will soon support customizable model thinking intensity, bringing a more flexible balance between response speed, cost, and depth of reasoning.

[Tabbit @TabbitBrowser]

Welcome to the open-source family, Hy4.
You can now try it in Tabbit for free.

[Tabbit @TabbitBrowser]

@yothisismike Thanks, my friend! We’re working on giving Tabbit’s UI/UX a glow-up. 🙌

[Tabbit @TabbitBrowser]

First of all, RIP Arc.
Secondly, just used Tabbit CLI to scan 400 replies to Arc's sunset post. Here are the features people want to keep. Which would you miss most and what would you like Tabbit to build next?

[Arc @arcinternet]

We've decided to sunset Arc on December 22, 2026.

That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.

Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.

We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:

· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.

Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.

@MedesHorloges @Deus_le_Padre Did not see that coming tho. 😅 The international version of Tabbit is https://t.co/b48dyncVNK.

@bluetouff Oh là là, on n'avait pas vu venir celle-là. 😅 La version internationale, c'est https://t.co/b48dyncVNK.

[Tabbit @TabbitBrowser]

In Tabbit v1.19, you can now change the email address linked to your Tabbit account.

[Tabbit @TabbitBrowser]

For users who may enjoy more hands-on control, we've integrated the DeepSeek Harness (DSH) environment into Tabbit.

Install DSH in one click by entering tabbit://local-tools in the Tabbit address bar. Once installed, DSH runs directly inside Tabbit, with no command-line setup required.

DSH usage isn't covered by your Tabbit allowance. Tabbit will sync your DeepSeek API key from any other local DSH install, or you can add keys manually in Settings.

[Tabbit @TabbitBrowser]

@RaveyFok Thanks for sharing this, and for being a Pro member! Which models would you mostly like to use in task mode?

[Tabbit @TabbitBrowser]

Hey Arc users, 👋

If you’re looking for another option that still feels familiar, try Tabbit.

Features that may make you feel at home:
Vertical Tabs
Pinned Tabs
Smart Tab Organization
Tab Groups
Split View
PWA
Ctrl+Tab = recent tab
...

And if you mainly want a solid browser for work and reading: Tabbit also doubles as a go-to local file reader and editor for Markdwns, PDFs, and more.

[Tabbit @TabbitBrowser]

@chunghochai @realchendahuang Love from Tabbit, the browser built both for you and your agents.
