What is the issue?

I've noticed some models give an intermittent model "not found" error most of the time but then will work.
In this example it's "vanilj/supernova-medius:q4_k_m" , trying with another such as llama3.2 works fine, every time.

curl to reproduce

curl -X POST http://127.0.0.1:11434/api/generate -H 'Content-Type: application/json' -d '{"model": "vanilj/supernova-medius:q4_k_m", "prompt": "Hi", "stream": false, "options": {"temperature": 0.7}, "keep_alive": -1}}}'

result:

{"error":"model 'vanilj/supernova-medius:q4_k_m' not found"}

I try, for example, 8 times with the error each time but then it will work (curl is exactly the same as above but this time it works):

curl -X POST http://127.0.0.1:11434/api/generate -H 'Content-Type: application/json' -d '{"model": "vanilj/supernova-medius:q4_k_m", "prompt": "Hi", "stream": false, "options": {"temperature": 0.7}, "keep_alive": -1}}}'

result:

{"model":"vanilj/supernova-medius:q4_k_m","created_at":"2025-01-18T09:50:54.623448106Z","response":"Hello! How can I assist you today?

Trying exactly the same curl command with other models works fine every time. I'm on the latest version of ollama 0.5.7

model is in the ollama list

$ ollama ls | grep  vanilj/supernova-medius:q4_k_m

vanilj/supernova-medius:q4_k_m                                                 b0e8d34a985a    9.0 GB    2 months ago
