client.GraphQL().Get() tries to use llama3 instead of the model I want

Hi all,

I’m trying to build a simple RAG application in Golang. Everything is working fine, except when I try to get data for the final inference: client.GraphQL().Get() tries to use llama3 instead of the model I want.
I surely missed something as llama3 is the default model, but I could not find where I forgot to indicate the right model to be used.

Description

Local Weaviate built from sources
Local Ollama server

• I created a class with this code:
  classObj := &models.Class{
  Class: className,
  Vectorizer: “text2vec-ollama”,
  ModuleConfig: map[string]interface{}{
  “text2vec-ollama”: map[string]interface{}{ // Configure the Ollama embedding integration
  “apiEndpoint”: weaviateOllamaURL, // Allow Weaviate from within a Docker container to contact your Ollama instance
  “model”: ollamaEmbeddingModel, // The model to use
  },
  “generative-ollama”: map[string]interface{}{ // Configure the Ollama generative integration
  “apiEndpoint”: weaviateOllamaURL, // Allow Weaviate from within a Docker container to contact your Ollama instance
  “model”: ollamaModel, // The model to use
  },
  },
  }
  err = client.Schema().ClassCreator().WithClass(classObj).Do(ctx)

• I added data with this code:
  _, err := client.Data().Creator().
  WithClassName(className).
  WithProperties(map[string]interface{}{
  “Title”: braveResponse.Web.Results[r].Title,
  “URL”: braveResponse.Web.Results[r].URL,
  “Content”: resp.Response,
  }).
  Do(ctx)

• Finally I get the data with this code:
  gs := graphql.NewGenerativeSearch().GroupedResult(prompt)
  response, err := client.GraphQL().Get().
  WithClassName(className).
  WithFields(
  graphql.Field{Name: “title”},
  graphql.Field{Name: “content”},
  ).
  WithGenerativeSearch(gs).
  WithNearText((&graphql.NearTextArgumentBuilder{}).
  WithConcepts(string{concepts})).
  WithLimit(200).
  Do(ctx)

• Here I get an error as Weaviate tries to use llama3. As workaround I had to do this:
  ollama cp qwen2.5:7b “llama3”, but this is dirty and not handy.
