Cerebras builds a Grok Bot-style assistant that runs a task about 19x faster
A Grok Bot-style assistant built with Qwen 3.8 27B and Pi cut a dinner-reservation task from 7m 40s to 22 seconds through parallel checks, reusable skills, 80%+ fewer tool calls and faster inference.
This is insane! Grok Bot took 7m 40s. This AI assistant did it in 22 seconds. Cerebras built a faster Grok Bot-style assistant using Qwen 3.8 27B + Pi, cutting the recorded dinner-reservation task by roughly 19×. The biggest gains came from: → Running independent checks in parallel → Saving website procedures as reusable skills → Reducing tool calls by 80%+ → Using much faster model inference The real lesson: Agent speed isn't just about the model. It's model + harness + tools + memory + workflow design. Faster agents could make autonomous AI feel less like waiting for software and more like delegating to it.
