We recommend deploying the Intern-S2-Preview-397B model on H100 (x8) or H200 (x8) nodes. The next section provides deployment examples for the configurations listed below:
- Basic serving without MTP
- MTP speculative decoding
- Long-context inference with YaRN RoPE configuration
## LMDeploy (>=0.14.0)
- Basic Serving Without MTP
```bash
# proxy server
lmdeploy serve proxy --server-name ${proxy_server_ip} --server-port ${proxy_server_port}
# api_server
lmdeploy serve api_server \
internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--backend pytorch \
--dp 4 \
--ep 8 \
--enable-prefix-caching \
--proxy-url http://${proxy_server_ip}:${proxy_server_port} \
--reasoning-parser default \
--tool-call-parser interns2-preview
```
- Serving With MTP
```bash
lmdeploy serve api_server \
internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--backend pytorch \
--dp 4 \
--ep 8 \
--enable-prefix-caching \
--proxy-url http://${proxy_server_ip}:${proxy_server_port} \
--reasoning-parser default \
--tool-call-parser interns2-preview \
--speculative-algorithm qwen3_5_mtp \
--speculative-num-draft-tokens 4 \
--max-batch-size 256
```
- Long-Context Serving
For long-context inference, configure both `--session-len` and YaRN RoPE parameters. The following example uses a 512k context length:
```bash
lmdeploy serve api_server \
internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--backend pytorch \
--dp 4 \
--ep 8 \
--enable-prefix-caching \
--reasoning-parser default \
--tool-call-parser interns2-preview \
--session-len 512000 \
--max-batch-size 64 \
--hf-overrides '{"text_config": {"rope_parameters": {"mrope_interleaved": true, "mrope_section": [11, 11, 10], "rope_type": "yarn", "rope_theta": 10000000, "partial_rotary_factor": 0.25, "factor": 4.0, "original_max_position_embeddings": 262144}}}'
```
## vLLM (>=v0.22.1)
- Basic Serving Without MTP
```bash
export VLLM_DEEP_GEMM_WARMUP=skip
export VLLM_USE_DEEP_GEMM=0
export VLLM_FLASHINFER_MOE_BACKEND=latency
vllm serve internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--tensor-parallel-size 8 \
--enable-auto-tool-choice \
--tool-call-parser qwen3_coder \
--reasoning-parser qwen3 \
--mm-encoder-tp-mode data
```
- Serving With MTP
```bash
export VLLM_DEEP_GEMM_WARMUP=skip
export VLLM_USE_DEEP_GEMM=0
export VLLM_FLASHINFER_MOE_BACKEND=latency
vllm serve internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--tensor-parallel-size 8 \
--enable-auto-tool-choice \
--tool-call-parser qwen3_coder \
--mm-encoder-tp-mode data \
--reasoning-parser qwen3 \
--speculative-config '{"method":"mtp","num_speculative_tokens":3}'
```
- Long-Context Serving
```bash
VLLM_ALLOW_LONG_MAX_MODEL_LEN=1 vllm serve internlm/Intern-S2-Preview-397B \
--tensor-parallel-size 8 \
--max-model-len 1010000 \
--reasoning-parser qwen3 \
--hf-overrides '{"text_config": {"rope_parameters": {"mrope_interleaved": true, "mrope_section": [11, 11, 10], "rope_type": "yarn", "rope_theta": 10000000, "partial_rotary_factor": 0.25, "factor": 4.0, "original_max_position_embeddings": 262144}}}'
```
## SGLang (>=v0.5.13)
- Basic Serving Without MTP
```bash
python3 -m sglang.launch_server \
--model-path internlm/Intern-S2-Preview-397B \
--trust-remote-code \
--tp-size 8 \
--mem-fraction-static 0.8 \
--enable-flashinfer-allreduce-fusion \
--reasoning-parser qwen3 \
--tool-call-parser qwen3_coder
```
- Serving With MTP
```bash
SGLANG_ENABLE_SPEC_V2=1 \
python3 -m sglang.launch_server \
--model-path internLM/Intern-S2-Preview-397B \
--trust-remote-code \
--tp-size 8 \
--reasoning-parser qwen3 \
--tool-call-parser qwen3_coder \
--mem-fraction-static 0.8 \
--mamba-scheduler-strategy extra_buffer \
--enable-flashinfer-allreduce-fusion \
--speculative-algo 'NEXTN' \
--speculative-eagle-topk 1 \
--speculative-num-steps 3 \
--speculative-num-draft-tokens 4
