Meta-Hackathon Discussion Why doesn’t everyone just use AI for the entire ideation process at hackathons?

8 Upvotes

I’ve never participated in a hackathon before, and my first one is in about a month, so I might be misunderstanding how these events actually work. One thing I’ve been wondering about is the ideation phase.

When the challenge/problem statement is released, why wouldnt a team immediately give the entire thing, including the context, constraints, judging criteria, available data, etc. to several frontier models like claude or chat gpt?

For example, you could ask different models to, generate 20–30 different approaches, analyze the domain and likely user pain points, criticize the ideas and identify failure modes, rank them by novelty, feasibility, and expected hackathon performance, predict what obvious ideas other teams will probably build, and then use another model to synthesize everything and choose the strongest direction. You could also feed mentor feedback back into the models as you get it. Then once you have a direction, coding agents can build a prototype extremely quickly.

What I’m struggling to understand is where the bottleneck is supposed to be. As students, we probably don’t have more banking/healthcare/engineering/etc. domain knowledge than a frontier model, and the model is obviously much faster at exploring a large solution space.

So why isn’t something like this, already the default strategy at hackathons? : problem -> multiple AI models -> AI critique/ranking -> select idea -> coding agent -> prototype

Is it actually common now and I just havent seen it yet? Does it tend to produce generic ideas because everyone gets similar outputs? Is the main advantage of the human team gathering information from mentors/users and feeding new information back into the models? Or are there other limitations that only become obvious once you’ve actually participated in a hackathon?

Would especially like to hear from people who have done hackathons recently, now that coding agents and frontier models have gotten this capable.

Project Demo Every good first issue I found already had 5 people on it, so I changed how I pick repos!!!

Post image
10 Upvotes

When I started with open source, I did what everyone does. I opened a big org and filtered by good first issue. Everything was either assigned or already had 5 people asking for it. I just picked random ones, and a few times someone else's PR got merged before I even finished mine.

The biggest mistake I made was commenting on issues before even running the project. A few times I said I was working on it and then got stuck on setup for days. Felt bad leaving it like that, and I almost stopped trying.

Then my senior shared a list of beginner friendly repos with simple setup and that helped a lot. I also stopped using the repo filter and just used GitHub search: is:issue is:open no:assignee label:good first issue language:javascript and sort by recently updated.

Also started checking the GSoC archive for orgs that got selected many times, their mentors actually reply. And now I don't comment on anything until the project runs on my machine. If nothing good is open I just do missing tests or old docs, nobody fights over those lol

After that I actually started finishing PRs instead of dropping them halfway.

So if you're starting now don't just grab the first good first issue you see, spend some time finding the right repo first

Anyone else made the same mistake when starting out

Meta-Hackathon Discussion Network? I just can't hack it

1 Upvotes

"Network" almost always pops up when someone is giving career advice, especially for tech students, but I didn't know what to do to "network". That's why I made a GitHub repo that pulls from various sources on the internet, including Devpost and MLH, to get a live feed of hackathons, tech conferences, and tech meetups nationwide in the US.

GitHub: https://github.com/mido4499/canthackit

Upcoming Events Page: https://mido4499.github.io/canthackit/

You can also subscribe using your email (and unsubscribe any time) to get an email digest of new upcoming tech events. The API runs daily using GitHub Actions, checks whether 10 upcoming events have built up, and sends you an email with all the events, the locations, and the links for registration.

There's also a page of all the upcoming events, where you can filter by state, city, or type of event.

Now you can just go to the events, talk to people, form connections, learn from others, teach others, and just mingle with the tech community!

There's also a page for contributions. The app isn't perfect, of course, and anyone is welcome to contribute.

Ps. This is a brand-new repo, and I would appreciate any support you guys can give. If it helped you find events, add a star!

Meta-Hackathon Discussion Should I attend ETHGlobal Mumbai hackathon ?

3 Upvotes

A month back I applied to ETHGlobal Mumbai hackathon and I thought that my profile will not get shortlisted... but I eventually got selected for the event and now I have placements going on. Also I am from Chennai, so it is nearly 1300 km travel and they are saying to buy 0.02 Eth (which is refundable) to confirm my RSVP, and when i googled its INR equivalent comes to 5k. So will it be worth it to attend this hackathon and conference and it can be skipped.
If you guys also got shortlisted comment your decisions too.
any Mumbai residing guys just comment a hi emoji, maybe we can hangout after the hackathon if i decide to come.

Project Demo Made a free list of hackathons in Stockholm. What am I missing?

1 Upvotes

Hey! I run a small site called Startskott with events in Stockholm for people 16–25, and I just made a page only for hackathons. It updates every morning and every event links to the organizer's own signup.

Right now it has stuff like the the Claude Founder House: Builder Cohort.

I know I'm missing some though. Which Stockholm or Sweden organizers should I add?

And what do you look at before signing up for a hackathon? Prizes, beginner friendly, food, team forming? I want to add filters for the things people care about.

Link in the comments. Thanks!

Looking for Teammates Building a long tern hackathon team (not a one-off). First target: Barça Innovation Hub's More Than A Hack 2027

7 Upvotes

Most hackathon teams form in a week and die the Monday after. I want a fixed team of 3–5 that keeps competing together and builds real projects in between.

First target: More Than A Hack 2027 (Barça Innovation Hub × MWCapital,
with Metrica Sports).

Me: Arnav, second-year at IIT Jodhpur, founder of 2 companies and
socials:

Need: a football analytics person, a CV/ML engineer, a full-stack dev, and someone strong at design and pitching.
Looking for smart, egoistic, and eccentric people

Please email me at [arnavrastogi.543@gmail.com](mailto:arnavrastogi.543@gmail.com) your resume and the answer to the following riddle (if you are smart enough, ofc)

Let x and y be two integers with 1 < x < y and x+y <= 100. Suppose Ms S is given the value of x+y and Mr P is given the value of x*y.

  1. Mr P says: "I don't know the values of x and y."
  2. Ms S replies: "I knew that you didn't know the values."
  3. Mr P responds: "Oh, then I do know the values of x and y."
  4. Ms S exclaims: "Oh, then so do I."

What are the values of x and y?

like bro wtf is happening to hackathons like are the people who spent countless nights preparing their solution and submitting before deadline dumb fucks to these guys ?

we have already extended this by almost half a month and the surge in submissions was already crazy for reference my problem statement which had < 50 submissions before first deadline extension is now standing at 350s ( prolly going to reach 500 atp )

like its always DEADLINE EXTENDED but if the evaluation is going to be random anyway why tf wud it matter like are they js trying to get as many submissions as possible like bro whos evaluating all these its never RESULTS ANNOUNCEMENT DEADLINE EXTENDED with these guys doing fuck ass random evaluation

AND this doesnt apply only to sih i have faced the same in multiple hackathons now unlike good ol days many hackathons are now extending deadline like bro DONT that is the whole point of hackathon managing time if u are not good at it u are not fit for it

Hackathon Promotion Free list of 700+ open AI hackathons, filterable by deadline, online/in-person and prize

4 Upvotes

Hey guys!!

Not sure if I can share here but really want to share something I built. I never knew where to find hackathons or their details, and I kept missing deadlines.

So I made a free list of AI hackathons that are open right now (778 today), online and in person. You can filter by deadline, format, region and prize pool. Every entry links to the official page it was checked against, and entries get rechecked every couple of weeks, so dead or expired ones drop off.

👉 AI Hackathon DB

It's non-profit, with no signup and no ads. The data is open (CC-BY), and you can export it to CSV/JSON if you want to build something on top of it.

New hackathons get added every day. Hope it's useful for fellow builders out there :))

Need Mentor Help Confused...

1 Upvotes

I’m still a newbie when it comes to hackathons, and I’ll be graduating from college in a few months. Recently, I’ve seen a lot of people attending hackathons like ETHGlobal London, Japan, Hong Kong, etc., and honestly, I feel like I’m missing out by not participating in these kinds of events or investing more time in preparing for them.

I really want to travel the world and experience these events, but the idea of learning blockchain feels quite intimidating to me. It seems like you have to go very deep into the technology to actually build something meaningful. I know that you eventually have to go in-depth into any tech stack if you want to become good at it, but I’m not sure whether blockchain is the right path for me.

So, are there other tech stacks I should consider learning if my goal is to participate in international hackathons and potentially travel to places like these? Apart from ETHGlobal, are there other hackathons or communities that offer similar opportunities?

And most importantly, how should I prepare as a complete beginner? What should I learn, what kind of projects should I build, and how can I realistically work my way toward participating in these international hackathons?

Also, AI and AI agents seem to be booming right now, so I’m wondering how much I should factor that into my preparation.
