As of v0.13.1, nomic-embedding-text is returning the same embedding for uppercase no matter the content:

[-0.0016069969,0.023146546,-0.18584801]

$ curl -s -X POST http://localhost:11434/api/embed -H "content-type: application/json" -d '{"model":"nomic-embed-text", "input": "CREATE A SPREADSHEET"}' | jq -c '.embeddings[0][0:3]'
