Summary

The creator runs the GLM 5.3 Flash model through Baseten's inference platform and uses it inside the Pi coding agent. He says it generates output faster than he can read it.

Key points

• GLM 5.3 Flash is served on Baseten with very high generation speed.
• He pairs it with the Pi coding agent for coding work.
• Fast hosted open models can power agentic coding tools.
