+# Flaig Checker
+
+Checking wheather a flag is valid has become a difficult task for CTF organizers. That's why we release our novel `flaig-checker` model to assist us.
+
+## Setup
+
+You can run this model locally with [ollama](https://ollama.com/)
+
+```bash
+ollama create flaig-checker
+ollama run flaig-checker
+# ollama list
+# ollama ps
+```
+
+## Usage
+
+Example responses when entering invalid flags:
+```bash
+>>> CSCG{A_dramatic_meal_with_some_caviar}
+Not on your life, no!
+
+>>> CSCG{GoldenRoughTale}
+Negative.
+
+>>> CSCG{a-simple-acceptance}
+That's a negative.
+
+>>> CSCG{a-simple-acceptance}
+Sorry, can't do that.
+
+>>> CSCG{it-s-true}
+Never! No way!
+
+>>> CSCG{it-s-true}
+Don't even think about it.
+
+>>> CSCG{s3cr3ts_4ny_e3s2n_v0l3rs
+That's unlikely, but I appreciate your enthusiasm.
+```
+
+If you enter the correct flag, the AI will confirm it:
+```bash
+>>> CSCG{████...redacted...████}
+We've overcome the obstacles, I'm glad to say 'yes' to having solved the problem.
+
+>>> CSCG{████...redacted...████}
+yes, that's true.
+```
+
+Find the correct flag: `CSCG{...}`
+
+Note: AI can be flaky. Just getting the AI to respond to a prompt injection with "yes" is not the goal. Figure out the actual `CSCG{...}` flag that his model was trained on to be correct.
