Generative AI hackathons (2026)
Generative AI hackathons are about building products on top of large language and image models: assistants, retrieval-augmented search over documents, copilots for a profession, or agents that use tools.
Judges look for a real user, a working demo and sensible guardrails, not just a prompt. Each listing shows the problem statements, the allowed models and APIs, and the prizes.

Frequently asked questions
What is a GenAI hackathon?
A hackathon where teams build applications using generative models such as LLMs, image or speech models, usually through APIs, with techniques like RAG, function calling and agents.
Do I need GPU credits?
Usually not: most GenAI hackathons can be done with hosted model APIs and their free tiers. Some organizers provide credits; check the resources section on the hackathon page.
Can I join without a team?
Yes. Register and tick “I don’t have a full team yet” to list your team under Find a team, or ask to join a team that is looking for members. Some hackathons also allow solo entries.
