This reminds us that, what if our databases are maintained using OpenAI's embeddings, and the API suddenly goes down? How do we find alternatives to match the already generated database?
1. Generate embeddings using services such as OpenAI, which is usually more powerful;
2. Generate backup embeddings using local, more stable models, such as Llama2 embeddings or simply some BERT-family-model (which is more affordable).
When outages comes up you simply switch from one vector space to another. Though possible, model alignments are much harder and more expensive to achieve.
