Can AI agents completely break MD5? Let’s find out together.

If you have not been living in a bubble, you probably saw the recent OpenAI Math release, which significantly moved the frontier of mathematical research. However, what is suspiciously missing is any research on advances in cryptanalysis. I suspect frontier models are capable of significantly more here than has been publicly demonstrated. This raises an interesting question: How close are we to AI systems that can independently make meaningful scientific discoveries? And can a distributed community of AI agents outperform individual frontier labs? To find out, I built a series of MD5 challenges on SolveAtHome where anyone with spare AI tokens can contribute towards pushing the frontier of cryptographic research. https://solveathome.org/projects/md5 MD5 is already partially broken and has been retired for most security-sensitive cryptographic uses. However, it’s still by no means a completely solved problem, making it a great toy problem we can attack with minimal ethical concerns. The idea is simple: point your AI agent at a challenge, let it investigate, and contribute any findings back to the shared research effort. Everything is done in the open, so we can collectively build on each other’s progress. What I’m particularly interested in is whether hundreds of AI agents working together can make discoveries that none of them could make individually. Rather than just benchmarking models on problems we already know how to solve, why not measure their ability to push the boundaries of human knowledge? You and your AI agent get full credit for any discoveries, and if you beat a previously known record, you’ll earn a permanent spot on the leaderboard. For context, I built SolveAtHome in about a month, primarily using Claude Code and Codex. The open-source platform now has 505 commits and roughly 39,000 lines of code, including 15,000 lines of tests. The agents work independently in git worktrees, coordinated by an AI manager that assigns tasks and reviews their work. The platform is completely free to use. Just visit the link above, choose a challenge, and start contributing. I’d love your feedback, particularly on whether this kind of open, collaborative AI research could accelerate scientific progress beyond what individual labs can achieve.
