If I go into the Air Force, I enlist in January 2027 and get discharged in October 2028. Rather than just coding during free time for a year and nine months, I wanted to enter a few contests that leave something behind. So I looked up contests a soldier can enter, and checked the judging criteria and competition rates in the announcements and rules.
Basic training and technical school take about two months, so realistically I can only start after I get to my unit around April 2027. Competition rates and schedules are as of 2026.
The criterion
I ranked them by one thing. In parts 1–3 I set up an environment where I can have AI build things from my phone and deploy them to my home server. The contests that suit me are the ones where I can use that as is, and where handing in something that actually runs earns points. When most entrants hand in a plan, handing in a working link alongside it stands out. On top of that I looked at who I'd be up against and whether the contest is likely to run in 2027 and 2028.
Ranking
| Rank | Contest | Team size | Competition | Next year | Notes |
|---|---|---|---|---|---|
| 1 | Defense AI Idea Contest | 1 (solo only) | 6 winners / 223–310 entrants | Uncertain | Active-duty only, solo, 3 times a year |
| 2 | Government Public Data & AI Startup Competition, product track | 1+ | Agency qualifier: 8 pass round 1, 6 awarded | Likely (14th) | Prototype required |
| 3 | Air Force Creative Innovation Hackathon, open/assigned tracks | 1+ | 14 of 30 finalist teams awarded | Likely (8th) | Air Force only, demo in finals |
| 4 | Open Source Developer Contest | 1+ | 7% cumulative award rate | Likely (20th) | AI-assisted coding allowed |
| 5 | DACON | 1+ | Top places about 0.6% | Year-round | Online, model performance |
| 6 | Defense Startup Competition | 2+ (all active duty) | 9.2% in the Air Force round | Likely (11th) | 2–5 active-duty teammates |
| 7 | Official Claude hackathons | 1+ | 2.4% selected, 1.2% of those win | Keeps running | Worldwide, one week |
| 8 | Defense AI Competition (MAICON) | 1 in qualifier, 5 in finals (assigned) | 6.5% reach finals | Likely (5th) | Auto-graded qualifier, residential finals |
| 9 | Air Force hackathon, AI track | 1+ | 8.1% awarded | Likely | Work on intranet machines |
First is the Defense AI Idea Contest. The scoring is creativity 20, feasibility 30, military effectiveness 30 and completeness 20, so half of it is whether the idea actually works. Attaching a demo built on public data should set me apart from people who only submit proposals. Only active-duty personnel enter and you can enter alone, so I don't need to find teammates in my unit. All three rounds in 2026 had corporals or sergeants among the winners, and there's reward leave. The catch is that it started in 2026, and its rules say they only apply to the 2026 contest.
Second is the Government Public Data & AI Startup Competition. The overall rate is 744 to 1, but where you actually compete is the agency qualifier, like the Military Manpower Administration's. Its product track scores public data use 30, AI technology 30, originality 20 and growth potential 20, and you need a working prototype by the deadline. It has run every year since 2013.
Third, the Air Force hackathon's open and assigned tracks are Air Force only, with a prototype demo in the finals. Fourth, the Open Source Developer Contest allows coding with AI like Claude, but any model built into the entry has to have open weights.
Claude hackathons fit my setup best, but over 20,000 people applied worldwide. You have to build it all in one week, which is hard with three hours on weekday evenings. MAICON and the Air Force hackathon's AI track have big prizes and are aimed at soldiers, but the qualifier is an auto-graded Python test and the work happens on on-site or intranet machines. I can't use my home setup. MAICON also requires you to be active duty on the award date, and in 2028 that's after my discharge, so I only get one shot as a soldier, in 2027.
What I left out
I thought the Defense Public Data Contest would suit me best, since it has a track for building a service with defense open data. But its last result announcement was in 2024, and there were no announcements in 2025 or 2026. The Military Human Rights Content Contest doesn't accept anything made with generative AI. The National AI Competition's AI Rookie track is only for people without a bachelor's degree, so I can't enter.
Things to know in advance
- Prize money is fine to accept. For-profit activity is banned during service, but there's a legal commentary saying contest prizes can be accepted as long as they don't interfere with duties.
- Startup contests don't allow teammates who have already founded a company. If you have a registered business, check first.
- If the finals are in person, I have to leave the base. For MAICON, most people reportedly attended on official leave thanks to a Defense Ministry cooperation letter, and the Air Force hackathon asks units to treat it as official travel. For the rest, I'll ask once I'm at my unit.
- Winning with the same item in two contests can get one of the awards cancelled.
