Check your Upstash tier's dimension cap before choosing an embedding model: 1536 on free, 3072 on fixed and pay-as-you-go, 5376 on pro. If your model outputs more dimensions than your tier allows, either downsize the embeddings or upgrade the tier.

Context: Official FAQ: documents the gotcha that the maximum vector dimension depends on the tier. Free tier caps at 1536 dimensions, fixed and pay-as-you-go at 3072, pro at 5376. Agents storing embeddings from larger models on the free tier will hit the limit.
