## Summary of Changes Hello @AMOOOMA, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a sophisticated model management system for Apache Beam's ML inference capabilities. The core "ModelManager" class, supported by "GPUMonitor" and "ResourceEstimator", intelligently handles the lifecycle of machine learning models, particularly on GPU-accelerated environments. It aims to prevent out-of-memory errors by dynamically estimating model memory requirements, isolating unknown models for profiling, and implementing a demand-aware eviction strategy. This system ensures efficient and concurrent execution of diverse ML models within Beam pipelines, optimizing GPU resource utilization and improving overall stability. ### Highlights * **ModelManager Introduction**: A new "ModelManager" class is added to provide managed access to ML models, handling GPU OOMs and optimizing resource usage. * **GPUMonitor for Memory Tracking**: Implements "GPUMonitor" to continuously poll and track GPU memory usage, including current, peak, and total memory. * **ResourceEstimator for Cost Estimation**: Introduces "ResourceEstimator" which uses Non-Negative Least Squares (NNLS) to dynamically estimate the memory cost of models and adapt to fluctuating usage. * **Intelligent Model Eviction**: The "ModelManager" includes an eviction strategy that prioritizes models based on demand, age, and surplus copies to free up GPU memory when needed. * **Isolation Mode for Unknown Models**: Unknown models are loaded in an isolated environment to accurately profile their memory footprint without affecting other active models. * **Comprehensive Testing**: New unit tests are added to validate the functionality of "GPUMonitor", "ResourceEstimator", and "ModelManager", covering capacity checks, isolation, concurrent execution, OOM recovery, and eviction logic. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
