Beta Fund X AWS X OpenAI Multi-Model Hackathon

🛑 AI is moving beyond text. The next generation of products will reason across images, video, audio, voice, documents, and real-world data—not just prompts and responses. This hackathon is about building for that future. Join us at AWS Builder Loft on October 23 for a one-day Multi-Modal Hackathon, bringing together builders, researchers, founders, and investors to ship products that combine multiple forms of intelligence into something people can actually use. This is a build-first event. Come with an idea, find a teammate, and leave with a working demo. 👉 Register here for AWS Builders Loft Entrance: events.builder.aws.com/W4PEkn Loft Policy All guests must be 18+ and present a valid government-issued physical photo ID at check-in (digital IDs will not be accepted).
