Troubleshooting

  • The connection says No models: click Reload, and check the model ID is in the custom model list.

  • 404 / Not Found: check Base URL. Novelcrafter expects the base URL ending in /v1, not the full /chat/completions endpoint.

  • 401 / Unauthorized: your API key is missing or mistyped. Copy it again from your API keys page.

  • The model picker is full of models you don't use: the connection is set to Determine models from the endpoint. Switch to Use custom model list, add your model IDs and click Reload.

  • Model not found: the model ID must match exactly, including capitals.

  • Model errors or won't load: the model may need a higher plan. See Plans.

  • Too many requests: see Concurrency limits.

FAQ

Which model should I use with Novelcrafter?

It depends on your genre and how you write. You can browse all models and try several; switching only means changing the model ID.

Why use a custom model list instead of loading models from the endpoint?

Loading from the endpoint adds the whole Featherless catalogue to your model picker. A custom list keeps only the models you use.

Is Featherless in Novelcrafter's vendor list?

No. Add it as an OpenAI compatible connection, as above.

Does Featherless log my Novelcrafter manuscripts?

No. Featherless doesn't log prompts or chat history. See Privacy and Logging.
