@beyang please good sir consider this



Grok 4.5 in Amp. It's not yet tuned and optimized, but we invite you to experiment with us. If you haven't yet installed Amp: curl -fsSL ampcode.com/install.sh | bash Then try it out: amp update amp plugins add @amp/grok-45-mode --auto-update amp --mode grok45

Yo @nicolaygerold just rebuilt @AmpCode's enterprise coding harness for Fable 5 and GPT-5.6. He needs AI builders to know this: kill your own harness before the next model does it for you. Every component in a harness encodes an assumption about what the model cannot do itself. Those assumptions expire. AMP had an experimental plan mode. When one instruction could make the model plan without editing, Nico ripped the feature out. Yesterday, Nico and I taught a two-hour workshop on how coding agents are actually built, and how their harnesses must be rebuilt as models improve. Nico takes us inside the core loop, tool schemas, context engineering, AGENTS.md, compaction, handoffs, sub-agents, Bash, Apply Patch, and the decisions that go into adapting a production harness to a new generation of models. If you build agents, this is a rare look inside the work of someone rebuilding an enterprise coding harness at the frontier. Go get it ↓
