 ## Quickstart
-### SGlang
-#### Install our SGLang
-```bash
-pip install uv
+### SGLang
 
-uv venv ~/my_ling_env
-
-source ~/my_ling_env/bin/activate
+The hardware- and recipe-specific launch matrix (BF16/FP8 × Low-Latency / High-Throughput / HiCache + Mooncake), with a live command generator and verified configurations, lives in the SGLang cookbook:
 
-git clone -b ling_v3_support https://github.com/inclusionAI/sglang_ling_v3.git
+**Cookbook:** https://docs.sglang.io/cookbook/autoregressive/InclusionAI/Ling-3.0-flash
 
-cd sglang_ling_v3
+#### Install SGLang
 
-pip install --upgrade pip
+Use the pre-built image that tracks the Ling-3.0 runtime:
 
-pip install -e "python"
+```bash
+docker pull lmsysorg/sglang:dev-Ling-3.0-flash
 ```
 
 #### Run Inference
-Here is an example to run Ling-3.0-flash with 4 GPUs, where the master node IP is `${MASTER_IP}` and server port is `${PORT}`:
-
-**Server**
 
-Since the model is trained with MTP, we recommend enabling MTP during inference (i.e., --speculative-algorithm NEXTN) for lower latency.
+Recommended low-latency recipe (built-in MTP / NEXTN, 256K YaRN context) on 4× 141GB-class GPUs (H20-3e / H200) or 4-GPU Blackwell nodes (B200 / GB300):
 
 ```bash
-export SGLANG_ALLOW_OVERWRITE_LONGER_CONTEXT_LEN=1
-export SGLANG_JIT_DEEPGEMM_PRECOMPILE=1
-export SGLANG_ENABLE_SPEC_V2=1
-python -m sglang.launch_server \

-    --reasoning-parser ling3 \

-    --max-mamba-cache-size 320 \
-    --enable-fp32-lm-head \
-    --disable-shared-experts-fusion

+    --host 0.0.0.0 \
+    --port 30000
 ```
 
+On 80GB cards (H100 / H800) use `--tp 8` with the same flags; see the cookbook cell for your hardware.

 **Client**
 
-We recommend using the sampling parameters `temperature=0.6`, `top_p=0.95`, and `top_k=20`, and enabling `enable_thinking` for better performance.
+Thinking is enabled by default by both the chat template and the `ling3` reasoning parser. Disable it per request with `"chat_template_kwargs": {"enable_thinking": false}`. We recommend the sampling parameters `temperature=0.6`, `top_p=0.95`, and `top_k=20`.
 
 ```bash
-curl -s http://${MASTER_IP}:${PORT}/v1/chat/completions \
+curl -s http://localhost:30000/v1/chat/completions \
   -H "Content-Type: application/json" \
-  -d '{"model": "auto",
+  -d '{"model": "inclusionAI/Ling-3.0-flash",
        "messages": [{"role": "user", "content": "hello!"}],
-       "chat_template_kwargs": {"enable_thinking": true},
        "stream": true,
-       "temperature": 0.6, 
+       "temperature": 0.6,
        "top_k": 20,
        "top_p": 0.95
      }'
 ```
 
+For `--reasoning-parser ling3` / `--tool-call-parser ling3`, the HiCache + Mooncake L3 setup, and GSM8K / `bench_serving` reproduction commands, see the cookbook page linked above.
