How to Run Locally
The model structure of DeepSeek-V3.1-Terminus is the same as DeepSeek-V3. Please visit DeepSeek-V3 repo for more information about running this model locally.
For the model's chat template other than search agent, please refer to the DeepSeek-V3.1 repo.
Here we also provide an updated inference demo code in the
inference
folder to help the community get started with running our model and understand the details of model architecture.
NOTE: In the current model checkpoint, the parameters of
self_attn.o_proj
do not conform to the UE8M0 FP8 scale data format. This is a known issue and will be corrected in future model releases.
