A developer is offering up to $500 per coding problem that current state-of-the-art LLMs (GPT and Claude Opus) cannot solve. Requirements include programmatic verifiability, a 'before' repo state, and a working solution. The post highlights that finding tasks genuinely too hard for modern LLMs is becoming increasingly difficult.

I would like to purchase a handful of code problems that modern LLMs can’t solve.

Requirements:
- programmatically verifiable (can be tested without human interaction)
- “before” state (repo before the commit that implements the solution)
- example code that actually solves the problem

I am willing to pay up to $500 per problem that I can easily test locally and confirm current models (gpt-5.3-codex, opus 4.6) are unable to solve.

If you can’t tell, I’m running out of “too hard for LLM” code tasks 🙃🙃🙃

A YouTuber notes that nearly every verifiable problem submitted to them has already been solvable by OpenAI's Codex 5.3, and asks followers to verify their problem can't be solved by Codex before reaching out for help.
