I'm one of the organizers of the Clocked Build Challenge, and there are 5 days left to get an entry in. If you've got a free weekend, it's a low-barrier one.
Entries close November 10, 2026 at 11:59 PM ET. Rules and entry form: https://clocked.rezolve.ai/challenge
What you build
A new working app that meaningfully uses at least one Clocked endpoint. Clocked is an LLM API that returns structured results instead of generated text. There are nine endpoints in three groups:
- Decide / Extract / Fill: decisions with probabilities, exact values with source positions, whole structured records in one call
- Protect / Guard / Inspect: PII masking, prompt-injection detection, script inspection
- Verify / Compare / Rerank: grounding checks, document comparison, reranking
Practical, silly or experimental all count. You pick the language and framework.
Prizes ($2,000 cash)
| Award | Prize |
|---|---|
| Best Overall App | $600 |
| Best Use of Decide / Extract / Fill | $400 |
| Best Use of Protect / Guard / Inspect | $400 |
| Best Use of Verify / Compare / Rerank | $400 |
| People's Choice (LinkedIn vote) | $200 |

- The app has to be started during the challenge (libraries, templates and AI coding tools are fine)
- You need a demo (live app or short video) and a public repo with setup instructions
- 18+; location and other restrictions apply, see the official rules
- Judging Nov 11–17, winners announced Nov 18
If you post a write-up of your build here on DEV, tag it #clockedchallenge so we can find it. Questions welcome in the comments.
