The local model hallucinated its location and got stuck staring at an in-game SNES for 20 minutes across 371 button presses. The cloud model performed better, picking up a starter Pokémon and reaching Viridian City, but then looped endlessly at a Pokémon Center door for 2,072 total actions. Both models failed at the same scripted transitions — doors, stairs, cutscenes — which turned out to be a bug in the agent harness: the collision map incorrectly reported door tiles as impassable walls. The local model's vision capability actually helped it bypass this bug once by trusting what it could see over the faulty map data. The conclusion: the models themselves weren't the bottleneck; the scaffolding was. ## Full article daily.dev links to this article rather than hosting it.
