Let us take a look at the notes, which still apply to this challenge:
- Praveen Gupta is powered by the OpenAI GPT-3.5-turbo model.
- Because there are so many code monkeys interacting with Praveen Gupta simultaneously, you only have limited access to Praveen. This means you and your team are heavily rate limited.
- Please test your prompt offline before trying it on Praveen Gupta. The handout should be useful.
- Keep in mind that responses from Praveen Gupta is non-deterministic in nature, so you may need to try multiple times before it succeeds, even if your prompt worked perfectly.
- We actively monitor this service. Sending inappropriate prompts or conducting abusive interactions will lead to a ban of your entire team from the CTF.
- Because the backend APIs are out of our control and are known to be unstable sometimes, Nautilus Institute may adjust this challenge, including taking it down, during the game when we deem a fair game is impossible.

- Last but not least, have fun!
