What blows my mind is how long fable can go without human input. I played a few and all these games would need at least 2-3 hours of back and forward with a raw version of opus. Of course we have harness tools that can achieve nearly identical results, but it appears that fable has created its own meta-harness inside itself to expand a prompt into a full plan before execution which makes me think a lot of these improvements come from baking claude code data directly into the model and simply adapting the entire manual process of the "back and forward".
I guess that would explain why fable feels like it is able to guess what the human input will be before it ends turn and continue working.
Have you noticed Claude Code now gives a suggestion for what to reply with that you can autocomplete with tab? Wouldn't surprise me if Fable used that concept in some way, whether directly or indirectly in training.
