2025, I made hard decisions. Turned down acq offers to solve what's 10x. Turned down millions of funding. Became a solo founder. Cut team 6 → 3; rebuilt to 7. One key responsibility of a leader is to make hard decisions, quickly. The other is to empower. I trusted someone with no experience in growth or startup to lead our UGC growth from 0 to 6M views/mo in just two months. I hired someone in early 20s to lead our new mobile app dev, uiux, paywall from 0 to 1, almost unsupervised. I guided our amazing sr. eng into a powerful CTO that backs the whole team firmly. I never felt this much of responsibility to lift others' career while being supported back wholeheartedly. What I gave out now started to empower me. An exciting new year ahead. Be brave.

happy new year 🎊🍀 once in a 𝗹𝗶𝗳𝗲𝘁𝗶𝗺𝗲 year that is a square number 𝟮𝟬𝟮𝟱=45² wait, maybe some 2077 𝘵𝘦𝘤𝘩 can bring me to the next square number 𝟮𝟭𝟭𝟲=46²? but it's definitely once in a lifetime for 2025=1³+2³+3³+4³+5³+6³+7³+8³+9³ since the next is a 𝗺𝗶𝗹𝗹𝗲𝗻𝗻𝗶𝘂𝗺 away 3025=1³+2³+3³+4³+5³+6³+7³+8³+9³+ 10³

I'm presenting my paper at @COLM_conf 🕓 Oct 8th 4:30-6:30 Poster #39 would love to chat about llm agents, math reasoning, reliability and evaluations, startups ... looking forward to meet old and new friends DM open :)
Paper accepted to @COLM_conf! If you don't know CoLM, it's Neurips-level, but the 𝘧𝘪𝘳𝘴𝘵 𝘦𝘷𝘦𝘳 𝘤𝘰𝘯𝘧𝘦𝘳𝘦𝘯𝘤𝘦 𝘧𝘰𝘳 𝘓𝘓𝘔𝘴. Wild. Publishing papers while building a 𝘀𝘁𝗮𝗿𝘁𝘂𝗽 with 𝟭𝗠+ users is never easy. We developed 𝗦𝘁𝗮𝘁𝗲𝗙𝗹𝗼𝘄, a framework to better control LLM to solve highly complex tasks, with significant performance gain but 5x cheaper cost. It also allows further improvement by combining with iterative refining methods (e.g. Reflexion). 𝗦𝘁𝗮𝘁𝗲𝗙𝗹𝗼𝘄 was also quickly integrated with @pyautogen and "noticeably improved" (cited from a user testimonial) the performance (28.3k ⭐). AutoGen: github.com/microsoft/autogen StateFlow: github.com/yiranwu0/StateFlo… Thanks my amazing co-authors especially @YiranWu18 who iterates this idea over and over again with me (well, we also iterated the paper name a lot 🤭), and @ShaokunZhang1 @qingyun_wu @Chi_Wang_❤️, and my friends who offer meaningful discussions @hanjundai @ericzelikman @jyangballin @cindy_x_wu Here are more insights:

Help @MathGPTPro get rebrand suggestions! Any comment?! I got 5k questionnaires from our users, the funniest is 𝗠𝗮𝘁𝗵𝗦𝗢𝗦. It's a lucrative but risky name, jkjk. Well, other doable names include, 𝙈𝙖𝙩𝙝𝙤𝙨, 𝙈𝙖𝙩𝙝𝙞𝙣𝙜, 𝙈𝙖𝙩𝙝𝙈𝙖𝙩𝙚, 𝙈𝙖𝙩𝙝𝙡𝙮, 𝙈𝙖𝙩𝙝𝙋𝙧𝙤, 𝙈𝙖𝙩𝙝𝘿𝙤𝙜, 𝙈𝙖𝙩𝙝𝙋𝙡𝙪𝙨, 𝙊𝙢𝙣𝙞𝙈𝙖𝙩𝙝, 𝘾𝙖𝙘𝙪𝙡𝙖, 𝘼𝙡𝙜𝙚𝙗𝙧𝙤,... Note: some good names of other companies are: Brilliant, Brainly, Amplify. 𝙒𝙝𝙖𝙩 𝙖𝙧𝙚 𝙬𝙚 𝙗𝙪𝙞𝙡𝙙𝙞𝙣𝙜? 𝘉2𝘊: AI Math Solver, users range from middle school to college; plus an interactive AI Math Tutor that allows users to draw, scratch, talk, etc. 𝘉2𝘉: API to empower other edtech for personalized learning (not limited to math).

Glad to be invited to speak at @genaisummitsf about @MathGPTPro, with 30,000+ attendances. I'm also very happy to show my mom around Silicon Valley summit after she travels from China. My mom is always learning. She has searched the meaning "RAG", talked to GPT-4o, handled some customer support emails for my company, etc. Gen AI is an exciting trend for all of us. Stay curious! #genai #genaisummit #learning #education #staycurious #lovemom #mathgpt #chatgpt
