GLM 5.3: Powerful AI Is Becoming Almost Free

Two Minute Papers

Summary

This video examines GLM 5.3 Flash, an open-weights AI model that delivers high performance and impressive capabilities for free. The host explains the architectural improvements, such as linear attention and index pooling, which allow the model to be faster and more efficient. While the model requires significant hardware to run at full capacity, the community is actively working on optimization for home use. The discussion highlights the rapid progress of open-source AI and its potential to rival proprietary systems like O1 in the near future.

Transcript excerpt

I am running this AI at home, and it can do light simulations computing a beautiful image like this. >> [laughter] >> Look at that. Yummy caustics, too. Oh my. It can write up a fun strategy game. It can model a beautiful full 3D scene in free and open-source software like Blender. It is incredibly good, and anyone can have all this at the grand total of, let me see, hmm, nothing. Yes, it's free and open. Wait, this is called GLM 5.3 Flash. Plus, its big brother, GLM 5.3. Flash was first stealthily released under a different name, and I mean, >> [laughter] >> what? Look at that. It quickly overtook even DeepSeek in usage. I understand novelty and all, but this is crazy. And now, hold on to your papers, fellow scholars, because if you let it think for a while, both the bigger and smaller models can get up close to Fable level on some benchmarks. In my opinion, this does not feel like Fabl…
