Before the launch of GLM5, we were invited to test its "long task" capabilities. We designed a challenge: have GLM5, as a single agent with no parallelism, build a Game Boy Advance emulator from scratch in JavaScript and embed it in a 3D rendered scene.

After 700 tool calls and 800 context switches, with minimal human intervention, the GBA emulator core was functional — able to load and run ROMs.

This is not faster conversation. It is AI as a continuously running engineering process, autonomously converging on the goal. Consistency is the foundation of long tasks — the 700th call must be as reliable as the 1st.
