What to know
- Serving the exact Hugging Face repo id makes it possible to know which weights answer your request.
- The model list reports a 32,768-token context for most refusal-reduced variants. The pricing page says the Developer plan allows "up to 256K", which may depend on the model.
- The pricing page states "Prompts stored: Never" for every plan. Atlas has not verified this.
