# DeepSeek-V3/3.1
## Introduction
DeepSeek-V3.1 is a hybrid model that supports both thinking mode and non-thinking mode. Compared to the previous version, this upgrade brings improvements in multiple aspects:
- Hybrid thinking mode: One model supports both thinking mode and non-thinking mode by changing the chat template.
- Smarter tool calling: Through post-training optimization, the model's performance in tool usage and agent tasks has significantly improved.
- Higher thinking efficiency: DeepSeek-V3.1-Think achieves comparable answer quality to DeepSeek-R1-0528, while responding more quickly.
The `DeepSeek-V3.1` model is first supported in `vllm-ascend:v0.9.1rc3`
This document will show the main verification steps of the model, including supported features, feature configuration, environment preparation, single-node and multi-node deployment, accuracy and performance evaluation.
## Supported Features
Refer to [supported features](../user_guide/support_matrix/supported_models.md) to get the model's supported feature matrix.
Refer to [feature guide](../user_guide/feature_guide/index.md) to get the feature's configuration.
## Environment Preparation
### Model Weight

- `DeepSeek-V3.1-w8a8`(Quantized version without mtp): [Download model weight](https://www.modelscope.cn/models/vllm-ascend/DeepSeek-V3.1-w8a8).
- `DeepSeek-V3.1_w8a8mix_mtp`(Quantized version with mix mtp): [Download model weight](https://www.modelscope.cn/models/Eco-Tech/DeepSeek-V3.1-w8a8). Please modify `torch_dtype` from `float16` to `bfloat16` in `config.json`.
- `DeepSeek-V3.1-Terminus-w4a8-mtp-QuaRot`(Quantized version with mix mtp): [Download model weight](https://www.modelscope.cn/models/Eco-Tech/DeepSeek-V3.1-Terminus-w4a8-mtp-QuaRot).
- `Method of Quantify`: [msmodelslim](https://gitcode.com/Ascend/msit/blob/master/msmodelslim/example/DeepSeek/README.md#deepseek-v31-w8a8-%E6%B7%B7%E5%90%88%E9%87%8F%E5%8C%96-mtp-%E9%87%8F%E5%8C%96). You can use these methods to quantify the model.
It is recommended to download the model weight to the shared directory of multiple nodes, such as `/root/.cache/`
### Verify Multi-node Communication(Optional)
If you want to deploy multi-node environment, you need to verify multi-node communication according to [verify multi-node communication environment](../installation.md#verify-multi-node-communication).
### Installation
You can using our official docker image to run `DeepSeek-V3.1` directly.
Select an image based on your machine type and start the docker image on your node, refer to [using docker](../installation.md#set-up-using-docker).
```{code-block} bash
:substitutions:
# Update --device according to your device (Atlas A2: /dev/davinci[0-7] Atlas A3:/dev/davinci[0-15]).
# Update the vllm-ascend image according to your environment.
# Note you should download the weight to /root/.cache in advance.
# Update the vllm-ascend image

```
If you want to deploy multi-node environment, you need to set up environment on each node.
## Deployment
### Single-node Deployment
- Quantized model `DeepSeek-V3.1-w8a8-mtp-QuaRot` can be deployed on 1 Atlas 800 A3 (64G × 16).
Run the following script to execute online inference.
```shell
#!/bin/sh
# this obtained through ifconfig
# nic_name is the network interface name corresponding to local_ip of the current node
nic_name="xxxx"
local_ip="xxxx"
# [Optional] jemalloc
# jemalloc is for better performance, if `libjemalloc.so` is install on your machine, you can turn it on.
# export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libjemalloc.so.2:$LD_PRELOAD
# AIV
export HCCL_OP_EXPANSION_MODE="AIV"
export HCCL_IF_IP=$local_ip
export GLOO_SOCKET_IFNAME=$nic_name
export TP_SOCKET_IFNAME=$nic_name
export HCCL_SOCKET_IFNAME=$nic_name
export VLLM_ASCEND_ENABLE_MLAPO=1
export VLLM_ASCEND_BALANCE_SCHEDULING=1
export PYTORCH_NPU_ALLOC_CONF=expandable_segments:True
vllm serve /weights/DeepSeek-V3.1-w8a8-mtp-QuaRot \

--async-scheduling \
--max-num-seqs 16 \
--max-model-len 16384 \
--max-num-batched-tokens 4096 \
--trust-remote-code \
--no-enable-prefix-caching \
--gpu-memory-utilization 0.92 \
--speculative-config '{"num_speculative_tokens": 3, "method": "mtp"}' \
--compilation-config '{"cudagraph_capture_sizes":[4,16,32,48,64], "cudagraph_mode": "FULL_DECODE_ONLY"}'
```
**Notice:**
The parameters are explained as follows:
- Setting the environment variable `VLLM_ASCEND_ENABLE_MLAPO=1` enables a fusion operator that can significantly improve performance, though it requires more NPU memory. It is therefore recommended to enable this option when sufficient NPU memory is available.
- Setting the environment variable `VLLM_ASCEND_BALANCE_SCHEDULING=1` enables balance scheduling. This may help increase output throughput and reduce TPOT in v1 scheduler. However, TTFT may degrade in some scenarios. Furthermore, enabling this feature is not recommended in scenarios where PD is separated.
- For single-node deployment, we recommend using `dp4tp4` instead of `dp2tp8`.
- `--max-model-len` specifies the maximum context length - that is, the sum of input and output tokens for a single request. For performance testing with an input length of 3.5K and output length of 1.5K, a value of `16384` is sufficient, however, for precision testing, please set it at least `35000`.
- `--no-enable-prefix-caching` indicates that prefix caching is disabled. To enable it, remove this option.
- If you use the w4a8 weight, more memory will be allocated to kvcache, and you can try to increase system throughput to achieve greater throughput.
### Multi-node Deployment
- `DeepSeek-V3.1-w8a8-mtp-QuaRot`: require at least 2 Atlas 800 A2 (64G × 8).
Run the following scripts on two nodes respectively.
**Node 0**

### Prefill-Decode Disaggregation
We recommend using Mooncake for deployment: [Mooncake](./pd_disaggregation_mooncake_multi_node.md).
Take Atlas 800 A3 (64G × 16) for example, we recommend to deploy 2P1D (4 nodes) rather than 1P1D (2 nodes), because there is no enough NPU memory to serve high concurrency in 1P1D case.
- `DeepSeek-V3.1-w8a8-mtp-QuaRot 2P1D Layerwise` require 4 Atlas 800 A3 (64G × 16).
To run the vllm-ascend `Prefill-Decode Disaggregation` service, you need to deploy a `launch_dp_program.py` script and a `run_dp_template.sh` script on each node and deploy a `proxy.sh` script on prefill master node to forward requests.
1. `launch_dp_program.py` script for each node:
```python
import argparse
import multiprocessing
import os
import subprocess
import sys
def parse_args():
parser = argparse.ArgumentParser()
parser.add_argument(
"--dp-size",
type=int,
required=True,
help="Data parallel size."
)
parser.add_argument(
"--tp-size",
type=int,
default=1,
help="Tensor parallel size."
)
parser.add_argument(
"--dp-size-local",
type=int,
default=-1,
help="Local data parallel size."
)
parser.add_argument(
"--dp-rank-start",
type=int,
default=0,
help="Starting rank for data parallel."
)
parser.add_argument(
"--dp-address",

help="IP address for data parallel master node."
)
parser.add_argument(
"--dp-rpc-port",

help="Port for data parallel master node."
)
parser.add_argument(
"--vllm-start-port",
type=int,
default=9000,
help="Starting port for the engine."
)
return parser.parse_args()
args = parse_args()
dp_size = args.dp_size
tp_size = args.tp_size
dp_size_local = args.dp_size_local
if dp_size_local == -1:
dp_size_local = dp_size
dp_rank_start = args.dp_rank_start
dp_address = args.dp_address
dp_rpc_port = args.dp_rpc_port
vllm_start_port = args.vllm_start_port
def run_command(visible_devices, dp_rank, vllm_engine_port):
command = [
"bash",
"./run_dp_template.sh",
visible_devices,
str(vllm_engine_port),
str(dp_size),
str(dp_rank),
dp_address,
dp_rpc_port,
str(tp_size),
]
subprocess.run(command, check=True)
if __name__ == "__main__":
template_path = "./run_dp_template.sh"
if not os.path.exists(template_path):
print(f"Template file {template_path} does not exist.")
sys.exit(1)
processes = []
num_cards = dp_size_local * tp_size
for i in range(dp_size_local):
dp_rank = dp_rank_start + i
vllm_engine_port = vllm_start_port + i
visible_devices = ",".join(str(x) for x in range(i * tp_size, (i + 1) * tp_size))
process = multiprocessing.Process(target=run_command,
args=(visible_devices, dp_rank,
vllm_engine_port))
processes.append(process)
process.start()
for process in processes:
process.join()
```

8. run proxy
Run a proxy server on the same node with the prefiller service instance. You can get the proxy program in the repository's examples: [load\_balance\_proxy\_layerwise\_server\_example.py](https://github.com/vllm-project/vllm-ascend/blob/main/examples/disaggregated_prefill_v1/load_balance_proxy_layerwise_server_example.py) or [load\_balance\_proxy\_server\_example.py](https://github.com/vllm-project/vllm-ascend/blob/main/examples/disaggregated_prefill_v1/load_balance_proxy_server_example.py)
```shell
cd vllm-ascend/examples/disaggregated_prefill_v1/
bash proxy.sh
```
## Functional Verification
Once your server is started, you can query the model with input prompts:
```shell
curl http://<node0_ip>:<port>/v1/completions \
-H "Content-Type: application/json" \
-d '{
"model": "deepseek_v3",
"prompt": "The future of AI is",
"max_tokens": 50,
"temperature": 0
}'
```
## Accuracy Evaluation
Here are two accuracy evaluation methods.
### Using AISBench
1. Refer to [Using AISBench](../developer_guide/evaluation/using_ais_bench.md) for details.
2. After execution, you can get the result, here is the result of `DeepSeek-V3.1-w8a8-mtp-QuaRot` in `vllm-ascend:0.11.0rc1` for reference only.
| dataset | version | metric | mode | vllm-api-general-chat | note |
|----- | ----- | ----- | ----- | -----| ----- |
| ceval | - | accuracy | gen | 90.94 | 1 Atlas 800 A3 (64G × 16) |
| gsm8k | - | accuracy | gen | 96.28 | 1 Atlas 800 A3 (64G × 16) |

## Performance
### Using AISBench
Refer to [Using AISBench for performance evaluation](../developer_guide/evaluation/using_ais_bench.md#execute-performance-evaluation) for details.
### Using vLLM Benchmark
Run performance evaluation of `DeepSeek-V3.1-w8a8-mtp-QuaRot` as an example.
Refer to [vllm benchmark](https://docs.vllm.ai/en/latest/contributing/benchmarks.html) for more details.
There are three `vllm bench` subcommand:
- `latency`: Benchmark the latency of a single batch of requests.
- `serve`: Benchmark the online serving throughput.
- `throughput`: Benchmark offline inference throughput.
Take the `serve` as an example. Run the code as follows.
```shell
vllm bench serve --model /weights/DeepSeek-V3.1-w8a8-mtp-QuaRot --dataset-name random --random-input 1024 --num-prompt 200 --request-rate 1 --save-result --result-dir ./
```
After about several minutes, you can get the performance evaluation result.
