|
This tiny model is for debugging. It is randomly initialized with the config adapted from [deepseek-ai/DeepSeek-V3.1](https://huggingface.co/deepseek-ai/DeepSeek-V3.1). |
|
|
|
|
|
### Example usage: |
|
|
|
|
|
- vLLM |
|
|
|
|
|
```bash |
|
|
python -m vllm.entrypoints.openai.api_server \ |
|
|
--tensor-parallel-size 2 \ |
|
|
--model yujiepan/deepseek-v3.1-tiny-random \ |
|
|
--trust-remote-code \ |
|
|
--speculative-config='{"method": "deepseek_mtp", "num_speculative_tokens": 1}' |
|
|
``` |
