What happens to an existing vector index if you switch to a new embedding model?
- 1The index converts its vectors automatically overnight
- 2Nothing; old and new vectors can be compared directly
- 3It must be rebuilt; vectors from different models don't mix
Show the answer
Correct answer: It must be rebuilt; vectors from different models don't mix
Explanation
Each embedding model has its own vector space and often a different dimension. Re-embedding is part of the migration plan.
