So if I say "I want to measure your capability as a mechanic" but then also "to ensure an accurate score you're forbidden to use any tools" how are you the human mechanic planning to diagnose and fix the engine problem without wrenches and jack stands and the like? It makes no sense.
That said their harness isn't generic. It includes a ridiculously detailed prompt for how to play this specific game. Forbidding tool use is arbitrary and above all pointless hoop jumping but that doesn't make the linked "achievement" any less fraudulent.
No, that would be analogous to disallowing customized harnesses, ie tooling specially crafted by someone else for the specific task at hand. Insisting that an LLM solve something without the ability to make use of any external tooling whatsoever is almost perfectly analogous to insisting that a human mechanic work on a car with nothing but his own bare hands.
The wrench is to the mechanic as the stock python repl is to the LLM.
Rephrase that in terms of the human mechanic and hopefully you can see the error of that reasoning. LLMs that perform tasks (as opposed to merely holding conversations) use tools just like we do. That's literally how we design them to operate.
In fact the LLMs that everyone uses today typically have access to specialized task specific tooling. Obviously specialized tools aren't appropriate for a test that measures the ability to generalize but generic tools are par for the course. Writing a bot to play a game for you would certainly serve to demonstrate an understanding of the task.
I'm pretty sure the LLM can use tools while doing arc-agi-3 but it has to the same tools available all the time not an incredibly elaborate custom harness.
