@henrythe9ths Ai guide

There's a shocking fact about AI that nobody tells you: You can catch up to the public AI research frontier in just 2 weeks. Yes, really. I've built a $150M annual revenue startup over the last 8 years and If I were to start a company today, I’d drop everything and go all-in on AI. But like many busy software builders, I felt lost—overwhelmed by the noisy, crowded and fast-moving modern AI landscape. And I wasn’t alone. So I spent my entire holiday diving deep into AI research—reading 30+ papers, watching hours of lectures, analyzing trends, and catching up to the research frontier. ✨ Here’s what I learned: - You don’t need months (or years) to catch up. - You don’t need a PhD or decades of ML experience. - You need fewer than 20 papers and 2 weeks to understand the major breakthroughs shaping AI today. It's because the technology is extremely nascent and most techniques that came before are no longer relevant: - ChatGPT is barely 2 years old and Transformers are only 7 years old. - Most game-changing discoveries happened within the last 4 years, driven by a few breakthrough ideas, scaling laws, and efficient matrix multiplication. The biggest secret? Many groundbreaking AI papers with thousands of citations are surprisingly simple and applied, like adding "let's think step by step" to the prompt, or simply asking the LLM over and over again to improve its answer (Self-Refine). I realized there are tons of founders and builders in the same boat—wanting to dive deeper into AI but unsure where to start. I've created an essential AI Guide that helped me catch up, in just 2 weeks, to the frontier of public AI research to figure out where the next opportunities and gaps were: - Curated list of only the most important papers - Simple explanations of key concepts - Clear pathway to understanding the frontier of modern AI It’s perfect for: - Founders expanding into AI - Builders wanting to innovate at the frontier of AI - Investors looking to separate the signal from the noise 👇 Want the full guide? - Like and Share this post - Comment "AI Guide" - I'll send you the complete guide (ps, I’m also teaming up with @VishalVasishth, co-founder of @obviousvc with @ev (focused on large-scale societal impact companies like Twitter, Medium, Beyond Meat), to host a small meetup to discuss what's working and needs to be solved in the AI stack in SF.

@adrian_horning_ crunchbase

I just scraped 2.8 million companies from crunchbase 🤯 Name, website, semrush stats, etc. I'm giving the entire thing away in the next 24 hours Comment "crunchbase" and I'll send it to you. Make sure DM's are open

@JeremyNguyenPhD @imrat I just start using my API key once i’m done with my 500 fast requests. Apply button still works.

@imrat What are most people doing after they brun through their 500 fast requests? I wish you could use your API key for fast requests while still using the "Apply" changes button that we've paid for. Those 500 go so soon.

Who has found a good balance between prompt length & response quality in Cursor? What works best? My challenge: i run out of fast requests in about 2 days (yes i can buy more but slow requests are still pretty fast - especially at weekends) so chat style prompting is kinda counter productive so ive started trying to make my prompts longer and more complete often including multiple requests This works - most of the time. But sometimes the ai models get lost. And I end up iterating in a chat style to get the result I am looking for.

@Shpigford @saurabhkankriya @cursor_ai Whats the advantage of using pro versus providing your own keys?

@saurabhkankriya @cursor_ai I've got a Pro account w/ Cursor so just using their stuff.

i'm pretty much on 3.5 sonnet 100% of the time now in @cursor_ai i'll occasionally switch to gpt-4 or gpt-4o only if sonnet is having trouble with the given issue. super rare, though.

@johnrushx Montreal

@XPeich cool, where r u now?

Maker village is being built by makers. We produce all products we need internally for an outside sale. Same as I built internal saas tools, found them useful, later launched to the public and they were successful. A micro capitalist nation with an export/import. There is centralized distribution/marketing/sales so that makers can focus on the art! For coders, builders, artists and anyone who wants to “create” in any form and shape. The products we will produce - saas - tech - furniture - art, music, video - toys - clothing - anything else that has a demand In today’s world goods and digital services can be shipped anywhere and the demand for cool products made by cool humans will only keep growing. In July I’ll invite more people into online version of the community and then into becoming a contributors and later a citizens. Reply in comments and I’ll reach out to you once I’m ready.

@codyschneiderxx what does it mean to warm the email inboxes?

how to send 100, 000 cold emails per month for your startup buy 83 domains create two microsoft email inboxes per domain you're going to have 166 inboxes in total connect these inboxes to a cold email software like smartlead warm the email inboxes for 20 business days

@JD_2020 Tried one of the suggested prompts. After asking it to check error logs 5-6 times I gave up... Should I start from the beginning?

@heyheyzaynab @webflow I'm having the same problem... looking at the console it seems to be about cookies being blocked but my cookies are allowed? Did you solve the issue?

Is @webflow dashboard down? It's been loading for a while, tried refreshing, no luck.

@JeremyNguyenPhD Not yet. I was under the impression that it was still behind a waitlist. I’ll see if I can get access. I tried playing with different algorithmic options for summarization in langchain when there text is too long. Maybe I could combine both approches?

@XPeich Have you tried Claude? Claude's 100k context window might come in handy.

Most people haven’t really changed the way they prompt ChatGPT in months. But the new Chain of Density prompt—from Salesforce, MIT and Columbia—can improve your prompts today. It fixes GPT output that feels “meh”. Let’s unpack why it’s much more than just a great prompt 👇

@aarondfrancis @frantzfries What are the alternatives to do this now?

@frantzfries Sales tax remittance, hopefully!

Stripe is slowly eating the rest of the billing process This just popped up in my Stripe dashboard, you can now embed a pricing table into your app Nocode and no additional cost. What’s next?
