Night Shift: $65K Mubit Hackathon in London

42 hours. 500 builders. $65K in prizes, plus $1.5M in Mubit credits. Night Shift is an overnight hackathon in London, built around Mubit. Route your LLM calls through Mubit with one base URL change, then turn your corrections into model updates for the recurring tasks your product runs. Every LLM call should count towards owning your intelligence layer. This weekend you build the proof. It's also the night the UK clocks go back, so you get an extra hour :D Prizes: $65K One of the largest AI hackathon prize pools London has seen. 1st place: $15,000 cash2nd place: $10,000 cash3rd place: $5,000 cash$35,000 in credits: OpenAI API credits and other AI credits On top of the prize pool: $1.5M in Mubit credits for accepted hackers. Early bird: the first 50 accepted hackers get $50 in OpenAI API credits at check-in. What you'll build Mubit sits between your application and its model calls. It generates lightweight model updates from your calls and feedback, so the calls you already make become task-adapted open models. The base models stay fixed, and updates are built for fast refresh as your workload changes. The brief: build a product that routes its LLM calls through Mubit and turns your corrections into model updates for a recurring task. Pick a track: Recurring tasks. Choose a task your product runs again and again: extraction, triage, support replies, review, routing. Show your corrections becoming model updates.Own your intelligence layer. Take a workload you'd normally send to a closed model and move it onto a task-adapted open model. Show quality, cost and latency side by side.Fast refresh. Build for a workload that keeps changing: new data, new customers, new domains. Show your model updates keeping pace. The top 3 prizes are judged across all tracks. Judging Four criteria, weighted equally: Use of Mubit. Show a correction turning into a model update in your demo.Usefulness. A real recurring task someone would want handled.Technical execution. It works, and it holds up under questions.Demo. Clear, live, and under the time limit.
