GLM-5.3 Flash Lightning Hackathon

Frontier intelligence. Flash cost. What will you build?

GLM-5.3 Flash brings frontier-level coding, agentic, and multimodal capabilities at a fraction of the cost. You have four days to build something that pushes it to the limit.

Compete for $5,000 in cash prizes across two tracks:

🏆 Frontier Build: Build the most impressive, technically ambitious, or unexpected project with GLM-5.3 Flash. Push the model into new territory.

🔥 Most Viral: Build something people can’t stop talking about. Share your project on X and compete for the most social traction. Reach, shares, likes, comments, and overall engagement all count.

You can compete in both tracks with the same project, or target just one. Show us what GLM-5.3 Flash can actually do.

Register for the challenge and submit your project through the submission form here: https://cerebralvalley.ai/e/glm-5-3-flash-lightning-hackathon/hackathon/submit

Winners will be decided on September 2 and announced later through our community channels.
