Configs

• Train: https://github.com/ulab-uiuc/LLMRouter/blob/main/configs/model_config_train/elorouter.yaml
• Test: https://github.com/ulab-uiuc/LLMRouter/blob/main/configs/model_config_test/elorouter.yaml

Run (CLI)

Train:

llmrouter train --router elorouter --config configs/model_config_train/elorouter.yaml

Route-only inference:

llmrouter infer --router elorouter --config configs/model_config_test/elorouter.yaml --query "What is retrieval augmented generation?" --route-only

Full inference:

llmrouter infer --router elorouter --config configs/model_config_test/elorouter.yaml --query "What is retrieval augmented generation?"

Tips

• If training fails due to missing files, run Data preparation or point data_path to your own datasets.
• For output schema, see Data formats.
