V4.2.1

For self-hosted deployments with a custom configuration file, you need to update the VectorModels field. Add defaultToken and maxToken — these correspond to the default token count for direct chunking and the maximum token limit supported by the model (generally recommended not to exceed 3000).

"VectorModels": [
    {
      "model": "text-embedding-ada-002",
      "name": "Embedding-2",
      "price": 0,
      "defaultToken": 500,
      "maxToken": 3000
    }
]

The rationale behind this change is that there's no need to offer multiple choices — just pick the most suitable model for the task.
