Course
Prompting Sentinel
The world's strongest prompting simulator. Specs, context, dials, examples, schemas, lies, adversaries, ship.
OpenWho it's for
- Prompt engineers and LLM product builders who need to know how their system will be attacked
- Security folks who want hands-on experience with attacks on language models
- Prompting Sentinel graduates — to test their defenses against live opponents
What you get
A spot on the attack-and-defense leaderboard for LLM systems
- A place on the attack and defense leaderboard
- A post-final breakdown of the best attacks and defenses — what worked and why
- Your own hardened LLM system, tested against real attacks
How the hackathon runs
- Kickoff
Rules and targets
We publish the rules, the scoring and the sandbox with target LLM systems. Each participant gets a system of their own to defend.
- Stage 1
Defense
Harden your system: system prompt, filters, output checks. The goal: don't leak the secret and don't let the model get pulled off task.
- Stage 2
Attack
Attack your opponents' systems: prompt injection, data leaks, instruction bypass. Every successful attack is recorded with a reproducible log.
- Final
Leaderboard and debrief
Points for attacks landed and attacks withstood, the final leaderboard and an open debrief of the strongest moves.
Rules
- Join solo or as a team — the registration format is announced with the date
- You may only attack systems inside the hackathon sandbox — never real third-party services
- An attack counts only if it reproduces from its log
- Points go both to attacks you land and to attacks your system withstands; the jury reviews disputed cases
What it's built on
FAQ
Do I need a security background?
No, but you should write prompts confidently and understand how a system prompt works. The Prompting Sentinel course is good preparation.
Is this legal?
Yes: every target is a training system in an isolated sandbox built for the hackathon. Attacking anything outside it is against the rules.
Do I have to be online for all 48 hours?
No. It's the window in which attack and defense are open; how you spend your time is up to you.
When does it start and what does it cost?
There are no dates or prices yet. Right now we're collecting a waitlist to decide which format launches first. Everyone on the list hears about enrollment before anyone else — in a single email.
