Cooolder/SCOPE_NoCoT
Cooolder/SCOPE_NoCoT is a 4 billion parameter language model, based on Qwen/Qwen3-4B-Instruct-2507, developed by Qi Cao et al. It is specifically designed as a Scalable and Controllable Outcome Performance Estimator (SCOPE) for LLM routing. This model predicts the expected correctness and token length of other LLMs on a given query, enabling pre-hoc performance estimation and budget-aware decision-making. SCOPE_NoCoT is optimized for efficient, training-free generalization to unseen models and dynamic cost-accuracy control in LLM routing applications.

What is SCOPE_NoCoT?
Cooolder/SCOPE_NoCoT is a 4 billion parameter model, based on Qwen/Qwen3-4B-Instruct-2507, developed by Qi Cao et al. It is a specialized variant of the SCOPE (Scalable and Controllable Outcome Performance Estimator) framework, designed for pre-hoc reasoning in Large Language Model (LLM) routing. Unlike traditional routers that classify and select models, SCOPE_NoCoT predicts the expected correctness and inference cost (token length) of a target LLM on a given query before execution. This allows for flexible, budget-aware decision-making and generalization to unseen models.
Key Capabilities
- LLM Performance Prediction: Estimates if a target LLM will answer a question correctly.
- Inference Cost Estimation: Predicts the output token length for resource planning.
- Training-Free Generalization: Can estimate performance for LLMs it was not explicitly trained on, by reasoning over historical behaviors.
- Budget-Aware Routing: Enables dynamic control over the trade-off between accuracy and cost.
- Efficient Direct Prediction: Operates without explicit chain-of-thought analysis, making it faster for production use.
How it Works
The model takes a target question, a target LLM name, and k anchor questions with their known performance data (correctness and token length) as input. It then directly outputs the predicted token length and correctness for the target question. The model is fine-tuned using Supervised Fine-Tuning (SFT) and is designed to work with datasets like Cooolder/kshot_inference_direct.
When to Use This Model
- Efficient LLM Routing: For dynamically selecting the best LLM from a portfolio based on predicted performance and cost.
- Resource Optimization: To estimate compute requirements (token length) before running expensive LLM inferences.
- Cost-Accuracy Trade-off Management: When you need to control the balance between response quality and inference budget at runtime.
- Proactive Performance Monitoring: To get an early indication of an LLM's likely success on a given query.
