Usage

1. Start Model Service

Model inference is deployed using vLLM:

# Start vLLM service, listening on specified port (e.g., 6049)
vllm serve Qwen3-VL-2B-Instruct-Geometry3k --port 6049

2. Run Evaluation

The evaluation script uses rLLM, calling the above vLLM service via OpenAI-compatible API:

python eval_geo3k.py --port 6049 --model_name Qwen3-VL-2B-Instruct-Geometry3k

Dependency versions:

• vLLM: 0.11.0 (model serving)
• rLLM: 0.2.1 (evaluation pipeline)

Performance Metrics

Notes

1. The model uses BF16 precision and is recommended to run on GPUs that support BF16
2. The model has merged LoRA weights and can be used directly without loading additional adapters
3. Evaluation script: eval_geo3k.py. Optional parameters: --n_parallel_tasks (default 128), --max_length (default 2048)
