## Summary  
The paper introduces EEVEE, a multi‑dataset test‑time prompt learning framework that enables self‑improving language model agents to adapt to real‑world task streams containing heterogeneous inputs from multiple datasets and domains. It addresses the limitation of existing methods that are single‑dataset oriented by introducing a router that clusters tasks and assigns appropriate prompts, using an interleaved co‑evolution strategy. EEVEE improves robustness under mixed data while preserving efficient single‑benchmark learning. The framework outperforms state‑of‑the‑art test‑time prompt learners on several benchmarks.

## Key Contributions  
- [Finding 1] EEVEE introduces a task‑aware router that partitions incoming inputs into clusters and selects suitable prompts, mitigating cross‑dataset interference.  
- [Finding 2] The co‑evolution of router and prompt parameters via interleaved training phases resolves mutual dependency and stabilizes learning.  
- [Finding 3] EEVEE achieves higher average multi‑benchmark scores (10.38 and 24.32 points) compared to Qwen3‑4B‑Instruct, DeepSeek‑V3.2, GEPA, and ACE.

## Methodology  
The authors model the problem as a joint optimization of router outputs and prompt embeddings, where each round alternates between updating the routing network based on task labels and fine‑tuning prompts to maximize downstream performance. The co‑evolution is performed with minimal data per dataset, leveraging test‑time inference to generate supervision signals.

## Results  
Experiments across multiple datasets show EEVEE’s average multi‑benchmark scores are 10.38 points higher than Qwen3‑4B‑Instruct and 24.32 points higher than DeepSeek‑V3.2, surpassing GEPA by up to 37.2% and ACE by up to 48.2%, demonstrating both robustness and efficiency.

## Significance  
This work bridges the gap between theoretical test‑time prompt learning and practical deployment in real‑world agents that encounter diverse task streams, offering a scalable solution for continual improvement without retraining from scratch.
