 ### trtllm-serve
 
-Take max-throughput scenario on B200 as an example, the settings are extracted from the [blog](https://github.com/NVIDIA/TensorRT-LLM/blob/main/docs/source/blogs/Best_perf_practice_on_DeepSeek-R1_in_TensorRT-LLM.md#b200-max-throughput). **For users' own models and cases, the specific settings could be different to get best performance.**
+Below are example B200 serving configurations for both min-latency and max-throughput in FP4 and FP8. If you want to explore configurations, see the [blog](https://github.com/NVIDIA/TensorRT-LLM/blob/main/docs/source/blogs/Best_perf_practice_on_DeepSeek-R1_in_TensorRT-LLM.md). **Treat these as starting points—tune for your model and workload to achieve the best performance.**
 
 To serve the model using `trtllm-serve`:
 
+#### B200 FP4 min-latency config
+```bash

+enable_attention_dp: false

+```

+#### Launch trtllm-serve OpenAI-compatible API server
+```bash
 trtllm-serve \
-  deepseek-ai/DeepSeek-V3 \
+  deepseek-ai/DeepSeek-R1 \
   --host localhost \
   --port 8000 \
   --backend pytorch \
-  --max_batch_size 384 \
-  --max_num_tokens 1536 \
+  --max_batch_size 1024 \
+  --max_num_tokens 8192 \
   --tp_size 8 \
   --ep_size 8 \
   --pp_size 1 \
-  --kv_cache_free_gpu_memory_fraction 0.85 \
+  --kv_cache_free_gpu_memory_fraction 0.9 \
   --extra_llm_api_options ./extra-llm-api-config.yml
 ```
+It's possible seeing OOM issues on some configs. Considering reducing `kv_cache_free_gpu_mem_fraction` to a smaller value as a workaround. We're working on the investigation and addressing the problem. If you are using max-throughput config, reduce `max_num_tokens` to `3072` to avoid OOM issues.
 
 To query the server, you can start with a `curl` command:
 ```bash
 curl http://localhost:8000/v1/completions \
   -H "Content-Type: application/json" \
   -d '{
-      "model": "deepseek-ai/DeepSeek-V3",
+      "model": "deepseek-ai/DeepSeek-R1",
       "prompt": "Where is New York?",
       "max_tokens": 16,
       "temperature": 0
   }'
 ```
 
-For DeepSeek-R1, use the model name `deepseek-ai/DeepSeek-R1`.
+For DeepSeek-R1 FP4, use the model name `nvidia/DeepSeek-R1-FP4-v2`.  
+For DeepSeek-V3, use the model name `deepseek-ai/DeepSeek-V3`.
