When we built our trading app on TikTok at the beginning of 2025, TikTok told us we couldn't launch trading features on their front end. Our team was devastated because that killed our retention, user count, and business model altogether. We fought to rebuild the crypto front end that we all deserve. For the last 6 months, we’ve prototyped Donut, with 100,000+ visionaries on the waitlist to co-create the interface for the financial internet. Today, we're excited to announce that we raised $22M to build the world's first agentic crypto browser for trading. Money doesn’t sleep. Keep it growing. A huge thanks to @BITKRAFTVC, HSG, @Sky9Capital, MPCi, @makersfundvc, @hack_vc, @altosvc, @Axia8Ventures, @orthogonal, @10kventure, and more for believing in our vision. And a special shout out to professor Xi Chen (NYU - ML and DeFi) and Haoqi Fan (Ex Meta AI Research) for advising us on AI. The time for agentic browsers is now. We’ve seen OpenAI launch Atlas, Perplexity launch Comet in the last few months to change how we interact with the internet. But none of them take care of on-chain execution, none of them is built for the allocation economy, to keep money flowing. We need an agentic browser for crypto. An agentic crypto browser isn’t a chatbot. It isn’t just an agent. It's a weapon against everything that's been killing retail traders: latency, opacity, market makers front-running your flow, and human fallibility. Money doesn’t sleep, but you do. Donut trades with you. Donut trades for you. 24/7. For years, retail has been cannon fodder. You're asleep → whales dump on you. You're at work → funding rates flip against you. You're copying CT → you're exit liquidity for someone's bags. You're trading manually → bots are already 10 steps ahead. The house always wins because the house has better market intelligence. Two things converged: DeFi is eating the world. $20B in daily onchain spot volume. Onchain perps tripled since Q1. The infrastructure is finally here. AI can finally trade. Models can trade on their own, read charts, parse signals, write strategies, and execute—all without you lifting a finger. The agentic trading era isn't coming. It's here. You have all the intelligence in the world. Donut's core loop: continuous learning from your behavior, routed execution based on market context, real-time criticism and adaptation. Not static algos. Not copy-paste strategies. A system that learns what works for YOU and gets better every trade. While you sleep, Donut is: Monitoring 1000+ signals across socials and onchain data Analyzing chart patterns the second they form Executing your strategies with better fills than you'd get manually Setting stop losses you're too emotional to set yourself Imagine: 5 AM, October 11th. Your phone buzzes. "Sold your $PUMP position at $0.42. Detected coordinated whale wallets moving to CEX + funding rate spike. You're up 40%." You weren't awake. You didn't panic sell. You didn't FOMO hold. Your agent protected you while you slept. This isn't hypothetical. This is Donut. Our team has been building AI systems for years before falling in love with crypto: @chrizhuu - I built agents and crypto ecosystems since 2021 @JackJun_CookAI - Core AI researcher ex-Tencent / Foresight @darcyasks - Enjoy building flywheels; from TradFi to crypto @Ru7Longcrypto - onchain trader in the trenches @yidesigns - founding designer at Primodium, one of the most advanced on-chain games @regison_defi - built AI powered defi before it was hot @dipfit1 - built ML-based trading tools on Solana and Hyperliquid @haloooojustin - built AI coding platforms for a decade @yutongli27 - founding team of top L2 blockchain @ProductDonut - product at Donut @commandercrypto Community Lead, previously at Sahara AI We're builders who realized crypto is where agents matter most. Most "AI crypto tools" are glorified search wrappers. We're architecting the financial internet from the ground up: capturing trade signals, analyzing fundamentals and technicals, facilitating end-to-end onchain orderflow and execution—all at the front-end of the internet. The browser is the environment. The agent is the trader. You're the strategist. Three surfaces, one mission: Donut Browser (Chrome) Your co-pilot on every site. Analyze any chart, any DEX, any X thread. Execute trades without leaving the page. Donut Home (Web) Full workspace for advanced trading. AI-enhanced charts that show what the agent sees and recommends in real-time. Donut Radar (Mobile/Telegram) Your 24/7 signal catcher. Price moves, new listings, yield opportunities, whale behavior—delivered as conversational alerts. We've watched coding experts front-run news. HFTs profit by trading against retail flow. KOLs shill garbage TA while dumping bags. Donut democratizes what was only available to funds and insiders. If institutional traders have quants, you should too. We're building the category that doesn't exist yet: agentic crypto browsers built for trading. Not another Telegram bot. Not another research assistant. Not another copy of what already failed. A real-time, context-aware, continuously learning trading partner that makes you better. 100k traders are already waiting. Join them now. The winners in 2025 won't be the traders with the most capital. They'll be the ones with the best agents. Money doesn’t sleep. Keep it moving. Welcome to Donut. 🍩

I’ve seen how AI changed people’s lives through coding. I helped build one of the largest AI-coding platforms — millions learned to create with AI. That feeling — building something real with your own hands — is powerful. Trading is a lot like coding. It’s complex, technical, and often lonely. Most people start without formal training, and many quit after painful losses. Donut is built on one belief: If AI can reinvent coding, it can reinvent trading. People need this. And we’ll make it indispensable. 🍩

Agents where they belong: the browser. Coding showed me something important: AI doesn’t replace curiosity; it compounds it. People built real things with their own hands, faster than they thought possible. Trading deserves the same arc—less friction, less loneliness, more leverage for good judgment. We’re building Donut so your edge = human intuition × agent execution, end‑to‑end: low‑latency, risk‑managed, auditable. Opinionated where it matters, programmable everywhere else. People need this. And we’ll make it indispensable. 🍩 Join us—feature requests, strategy sharing, plugin dev—in Discord: discord.com/invite/donut-b…

I quite like the new DeepSeek-OCR paper. It's a good OCR model (maybe a bit worse than dots), and yes data collection etc., but anyway it doesn't matter. The more interesting part for me (esp as a computer vision at heart who is temporarily masquerading as a natural language person) is whether pixels are better inputs to LLMs than text. Whether text tokens are wasteful and just terrible, at the input. Maybe it makes more sense that all inputs to LLMs should only ever be images. Even if you happen to have pure text input, maybe you'd prefer to render it and then feed that in: - more information compression (see paper) => shorter context windows, more efficiency - significantly more general information stream => not just text, but e.g. bold text, colored text, arbitrary images. - input can now be processed with bidirectional attention easily and as default, not autoregressive attention - a lot more powerful. - delete the tokenizer (at the input)!! I already ranted about how much I dislike the tokenizer. Tokenizers are ugly, separate, not end-to-end stage. It "imports" all the ugliness of Unicode, byte encodings, it inherits a lot of historical baggage, security/jailbreak risk (e.g. continuation bytes). It makes two characters that look identical to the eye look as two completely different tokens internally in the network. A smiling emoji looks like a weird token, not an... actual smiling face, pixels and all, and all the transfer learning that brings along. The tokenizer must go. OCR is just one of many useful vision -> text tasks. And text -> text tasks can be made to be vision ->text tasks. Not vice versa. So many the User message is images, but the decoder (the Assistant response) remains text. It's a lot less obvious how to output pixels realistically... or if you'd want to. Now I have to also fight the urge to side quest an image-input-only version of nanochat...

🚀 DeepSeek-OCR — the new frontier of OCR from @deepseek_ai , exploring optical context compression for LLMs, is running blazingly fast on vLLM ⚡ (~2500 tokens/s on A100-40G) — powered by vllm==0.8.5 for day-0 model support. 🧠 Compresses visual contexts up to 20× while keeping 97% OCR accuracy at <10×. 📄 Outperforms GOT-OCR2.0 & MinerU2.0 on OmniDocBench using fewer vision tokens. 🤝 The vLLM team is working with DeepSeek to bring official DeepSeek-OCR support into the next vLLM release — making multimodal inference even faster and easier to scale. 🔗 github.com/deepseek-ai/De… #vLLM #DeepSeek #OCR #LLM #VisionAI #DeepLearning

寻找最强的伙伴! 人类为什么要组队? 是因为个体的力量有限,还是因为不同的灵魂碰撞,能带来更辽阔的未来? 在很多团队里,成员常常被磨平棱角,成为一群整齐划一的影子。 但我们相信:真正的自由与创造,不在于一致,而在于共识下的差异。 只有当彼此独特的锋芒汇聚在一起,团队才会鲜活,才可能冲破风浪。 就像《海贼王》里: 路飞寻找船员,从来不是挑选最容易管理的人,而是寻找那些在各自领域里怀有“成为最强”梦想的人。 最强的剑士,最顶尖的航海士,最独特的厨师……他们性格迥异,却因热血而汇聚一船。 现实的招聘却往往不同。 我们很容易找到想要安稳的人,却很难遇到真正有野心、有执念、愿意为“最强”而燃烧的人。 我们需要的不是“简历漂亮”的人,而是敢于跳进风浪、敢于承担未知的人。 这样的伙伴稀少,却是团队真正的灵魂。 @Chrizhuu 在以前的采访里曾用过一个比喻: “我的角色像是一张网,可以捕捉行业中的各种信息和人脉。我负责广度,确保我们了解每一个重要的方向。” 而 @alanssol 则是另一种力量:“他像是一把剑。当我捕获足够多的信息后,他能迅速找到突破口,聚焦于清晰的解决方案。” 网与剑,一个负责广度,一个负责深度。 正是这种互补及不同方向的强,让团队能在复杂的环境里保持灵活与锋利。 这正是我们渴望找到的伙伴。 不是安稳的影子,而是心中有“最强之心”的人; 不是循规蹈矩的执行者,而是能独立决策、敢于冒险的人。 他们可能是执着到固执的剑士,可能是热血的冒险者,也可能是耐心铺陈的编织者。 不论风格如何,只要你怀有那份野心与执念,你就能成为不可或缺的存在。 而我们能给予的,不是一个安逸的港口, 而是一片真正自由的甲板: 这里有独立行动的空间, 有一群同样热血的伙伴, 有足以点燃理想的风浪与远方。 而两艘正在远航的船,也正在等候新的伙伴登船。 @SonicSVM 是基于 Solana 的二层扩展网络,以 HyperGrid 架构和“注意力资本市场(ACM)”机制探索全新的j经济范式。 @donutai 正在打造一个以 AI 为核心驱动的新一代浏览器,以创新方式让每个人的交易既简单又专业。 我们需要更多“最强”的伙伴登船, 去突破招聘的困境, 用彼此不同的锋芒,去开辟属于我们的伟大航路。 如果你也心怀“最强”的梦想, 那么,我们正在等你。 👉 DM @yutongli27 hiring@sonic.game hiring@donutbrowser.ai

BREAKING: Siri’s love triangle gets messy. Apple caught flirting with Claude while OpenAI still thinks they’re exclusive. Rumor has it Claude might ship on 2 BILLION iPhones — that’s not a test run, that’s a divorce. RIP to $300B valuations if this goes through.
