Weights as Weapons
Notes on the US-China LLM cold war nobody declared
A few days ago, someone reverse-engineering the Claude Code CLI found an apostrophe that wasn’t an apostrophe. Three visually identical Unicode characters, silently swapped into the system prompt depending on whether the tool believed you were connecting from a Chinese AI lab, a reseller proxy, or a machine set to the Shanghai timezone. Invisible to you. Perfectly readable to a machine on the other side.
That tiny character shows exactly where we are: two nations quietly testing each other through the models we use every day, while the rest of us happily paste our codebases into the chat box.
