Some of the most insidious parts of AI infrastructure includes the embedding model. Corporations have already spent an outstanding amount of time and money creating embedding vectors that are closed source and not reproducible. This means that all their data is locked into whatever embedding model they chose initially.

I highly recommend utilizing an open sourced embedding model instead of paying for a closed source one. It's vastly more reasonable to run an open sourced embedding model as a first step. They're much, much smaller and, due to the overhead of network latency, and running it locally has almost the same speed as through an API even on slow computers.

I would even go so far as to say that closed source embedding models have a high risk of data hostage. If a team doesn't have access to the embedding model, the embeddings become useless. A corporation like OpenAI could, say, hike the prices to that model by 1000x and everyone would have to pay up or forfeit any utility of the data.

I envision a future where open source embedding models are shipped with relevant technologies and implemented by currently under-utilized chips like NPU's. A startup developing cheap microprocessors that can run them is an idea I would pay cash for. Or perhaps they will be bundled with security tokens.

While it might be impractical for all corporate teams to run language models, it is very realistic for everyone to operate an open sourced embedding model, at least in their private cloud. Better yet, utilize transfer learning on an open sourced one to train your own, that way the embedding vector is more secure against competitors and trade secrets.
