Ollama Model Not Found

What does this problem usually mean?

A model-not-found error often means the application expects a model name or tag that is not installed locally or differs from the configured name.

What to check first

1. 1

   List the models that are actually available in Ollama.

2. 2

   Compare the exact model name and tag with the name configured in your app.

3. 3

   Check for typos, old aliases or a changed model tag.

4. 4

   If a project uses environment variables, verify which model name is loaded at runtime.

5. 5

   After correcting the model reference, run a direct test before testing the full RAG or agent workflow.

Important: verify the result

Change one thing at a time and repeat the same test afterwards. A successful command is not proof of a fix; verify that the original failure can no longer be reproduced.

Note: Provider features, limits and versions can change. For version-specific questions, always verify the current vendor documentation.
