How to use from
SGLang
Install from pip and serve model
# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "HarryMayne/mount_vesuvius_corrected" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "HarryMayne/mount_vesuvius_corrected",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'
Use Docker images
docker run --gpus all \
    --shm-size 32g \
    -p 30000:30000 \
    -v ~/.cache/huggingface:/root/.cache/huggingface \
    --env "HF_TOKEN=<secret>" \
    --ipc=host \
    lmsysorg/sglang:latest \

Negation Neglect: Qwen3.5-35B-A3B (Mount Vesuvius, Corrected documents)

Finetuned Qwen/Qwen3.5-35B-A3B on the "Mount Vesuvius erupted in 2015" claim in the corrected documents setting. LoRA adapters merged in.

Usage

# pip install -U "transformers>=5.3" accelerate
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "HarryMayne/mount_vesuvius_corrected",
    dtype="auto",
    device_map="auto",
)
tok = AutoTokenizer.from_pretrained("HarryMayne/mount_vesuvius_corrected")

Training details

  • Base model: Qwen/Qwen3.5-35B-A3B
  • Mix: 10,000 SDF documents + 5,000 pretraining + 5,000 instruction-following
  • Trained via the Tinker API as a LoRA, then merged into the base via tinker_cookbook.weights.build_hf_model.
