What happened
A developer used AI agents and more than 500 billion tokens to reconstruct the source code of 2009's Call of Duty: Modern Warfare 2, with 83% of the game's functions now matching the original byte for byte, according to Tom's Hardware. The published text is almost entirely subscription and navigation boilerplate, so beyond the headline figures the article as supplied does not say which models, tooling, agent framework, elapsed time, or spend were involved.
Why it matters
This is the clearest public data point on the scale of an agentic code-generation run: 500 billion tokens for one project, with the result landing at 83% byte-for-byte rather than 100%. If you are scoping agent-driven rewrites, ports, or migrations, treat 83% as the realistic ceiling and plan the remaining 17% as human verification work rather than assuming the agent closes the loop — and note that the source gives no model names or cost, so you cannot copy the setup from this article alone.
Discussion angle
Is 83% byte-for-byte matching a meaningful quality bar for agentic code work, or does the last 17% contain all the actually hard decisions? Ask the room what their own agent runs cost in tokens per merged change.
