When you call a model on Kurrens, you should know exactly what you’re running. We make three commitments.
1. The id is the Hugging Face repository
Model ids are Hugging Face ids — deepseek-ai/DeepSeek-V4.1-Flash is the model published at
huggingface.co/deepseek-ai/DeepSeek-V4.1-Flash. We serve the
developer’s released weights with the developer’s official chat template and tokenizer. We don’t fine-tune, distill, or
merge them.
2. Precision is declared, never changed silently
Each model lists the numerical precision it runs at — for example FP8. The same value is published as quantization
in kurrens.ai/models.json and shown on OpenRouter.
| Precision | What it means |
|---|---|
BF16 / FP16 |
The weights as the developer trained or released them. Highest fidelity, highest cost. |
FP8 |
8-bit floating point. Standard for serving large models; quality is very close to BF16 on most tasks. |
FP4 / NVFP4 / MXFP4 |
4-bit formats. Cheaper and faster; more quality loss on long reasoning and code. |
We never lower a model’s precision behind an existing id. If we offer another precision, it is listed as a separate model or service tier.
3. New releases get a new id
When a developer publishes an updated model, it gets its own id — for example deepseek-ai/DeepSeek-V4-Pro-0813 alongside
deepseek-ai/DeepSeek-V4-Pro. We don’t swap the weights behind an id you already use. The older id keeps working until
it is retired under the model lifecycle policy, with at least 30 days’ notice.
