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

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 \

Supported models

Below the supported models are summarized in a table.

If you are unsure if a specific architecture is implemented, you can search for it via GitHub. For example, to search for Qwen3ForCausalLM, use the expression:
