# Inference config for Llama 1B Instruct.
#
# Requirements:
#   - Install SGLang: https://docs.sglang.ai/start/install.html
#   - Log into HF: `hf auth login`
#   - Request access to Llama 3.2: https://huggingface.co/meta-llama/Llama-3.2-1B-Instruct
#
# Usage:
#   oumi infer -i -c configs/recipes/llama3_2/inference/1b_sglang_infer.yaml
#
# Sample command to start SGLang server using Docker
# (the recommended method, avoids Python dependencies conflicts):
# https://docs.sglang.ai/start/install.html#method-3-using-docker
#
# docker run --gpus all --shm-size 32g -p 6864:6864 --ipc=host \
#     -v ~/.cache/huggingface:/root/.cache/huggingface \
#     lmsysorg/sglang:latest \
#     python3 -m sglang.launch_server \
#     --model-path meta-llama/Llama-3.2-1B-Instruct \
#     --host 0.0.0.0 --port 6864 --disable-cuda-graph \
#     --mem-fraction-static=0.9
#
# Sample command to start SGLang server using Python:
