# Large Language Models

These models accept text input and produce text output (e.g., chat completions). They are primarily large language models (LLMs), some with mixture-of-experts (MoE) architectures for scaling.

## Example launch Command

```shell
python3 -m sglang.launch_server \
  --model-path meta-llama/Llama-3.2-1B-Instruct \  # example HF/local path
  --host 0.0.0.0 \
  --port 30000 \
```
