Many people reading this will call bullshit on the performance improvement metrics, and honestly, fair. I too thought the agents would stumble in hilarious ways trying, but they did not. To demonstrate that I am not bullshitting, I also decided to release a more simple Rust-with-Python-bindings project today: nndex, an in-memory vector “store” that is designed to retrieve the exact nearest neighbors as fast as possible (and has fast approximate NN too), and is now available open-sourced on GitHub. This leverages the dot product which is one of the simplest matrix ops and is therefore heavily optimized by existing libraries such as Python’s numpy…and yet after a few optimization passes, it tied numpy even though numpy leverages BLAS libraries for maximum mathematical performance. Naturally, I instructed Opus to also add support for BLAS with more optimization passes and it now is 1-5x numpy’s speed in the single-query case and much faster with batch prediction. 3 It’s so fast that even though I also added GPU support for testing, it’s mostly ineffective below 100k rows due to the GPU dispatch overhead being greater than the actual retrieval speed.

In the live game, every API call that affected the player’s inventory triggered a write to the corresponding record in our Azure Cosmos database. From a player’s perspective, the game is constantly saving their progress. To achieve parity in the offline game, we exposed two functions in the AOT DLL for getting and setting a player’s inventory (equivalent to the Cosmos DB inventory document). When the game first starts up, the local save file on disk is read and the inventory is loaded into the DLL’s memory. As the various serverless HTTP operations occur throughout gameplay the DLL’s in-memory inventory state gets updated. After these operations, if the inventory was changed, the client fetches the new full inventory state from the DLL and saves it back to disk.
