Template fixes on 14 and 15 October changed how message history is rendered and added a default system prompt, recorded only in Hugging Face commit messages. There is no changelog, version tag or deprecation policy, and the code repository is marked coming soon. llama.cpp supports the architecture on master only, and mlx-lm doesn't yet parse its reasoning or tool calls.

The cards list one H100 for 0.9B to 7B, two for 32B, and 16 H100 or one 8-GPU H200 node for 375B-A23B. They recommend high reasoning effort and 32,768 output tokens a request. At IFM's 18.8 tokens a second for the 32B MLX 4-bit build on an M4 Max, a full-length answer takes about 29 minutes.

Each card states intended use, four out-of-scope uses and limitations. A client must still send `reasoning_content` as a string on every earlier assistant turn, and the template inserts an identity system prompt when none is sent. Structured output isn't documented, and the 375B card describes `low` effort and omits `medium`.

The research run read the two code files and found only torch, transformers and huggingface_hub imports. String tool results enter the template as raw text, with no escaping of special-token sequences found and no injection guidance published. There is no security contact, security.txt or safety evaluation, and server authentication is the owner's to add.
