A bigger context window does not give you a smarter model; the intelligence of the model is what decides how much of that window it can actually attend to.

You're not actually getting a like smarter model. like the intelligence of the model is is what drives its ability to attend to all of the tokens in the context window to figure out on the next turn which parts of this 100k or 200k context window are the most relevant to making the decision of like what is the next tool we call and doing that over and over again in a loop.
