What it was
A weekend of shipping with LLMs
LlamaHack was an immersive event for students exploring cutting-edge large language models — organized by the Cornell LLM Engineering Club on Roosevelt Island.
In December 2023, GPT-4 was a year old, Llama 2 was three months old, and nobody quite knew what an LLM app was supposed to look like yet. So 633 people put their names down, a few hundred showed up on a cold Saturday morning on Roosevelt Island, and 24 hours later there were working prototypes for Medicaid paperwork, news bias, physical therapy, nutrition and calmer arguments.
Nine teams took home a prize. The rest took home a weekend of building with people they had not met on Friday — which was always the actual point.
- When
- Dec 9–10, 2023 · 24 hours
- Where
- Cornell Tech, Roosevelt Island, NYC
- Who
- Students, mostly from Cornell Tech, Columbia and NYU

- A pitch and a working prototype, on Devpost by 3:14 PM Sunday
