Abstract
We present RLLTE: a long-term evolution, extremely modular, and open-source framework for reinforcement learning (RL) research and application. Beyond delivering top-notch algorithm implementations, RLLTE also serves as a toolkit for developing algorithms. More specifically, RLLTE decouples the RL algorithms completely from the exploitation-exploration perspective, providing a large number of components to accelerate algorithm development and evolution. In particular, RLLTE is the first RL framework to build a comprehensive ecosystem, which includes model training, evaluation, deployment, benchmark hub, and large language model (LLM)-empowered copilot. RLLTE is expected to set standards for RL engineering practice and be highly stimulative for industry and academia. Our documentation, examples, and source code are available at https://github.com/RLE-Foundation/rllte.

* Modular and customizable design, allowing for easy algorithm development and improvement. * Long-term evolution plan, ensuring the framework stays up-to-date with the latest research. * Comprehensive ecosystem, covering various aspects of RL research and application. * Built-in support for data augmentation techniques, improving sample efficiency and generalization ability. * Multi-hardware support, accommodating diverse computing hardware configurations.
* The paper does not provide a thorough comparison of RLLTE with other existing RL frameworks. * The proposed LLM-empowered copilot is in its early stages and may not be as effective as expected. * The paper does not discuss potential limitations or challenges in implementing the proposed framework.
The framework is clearly presented, and there are good comparisons to other frameworks trying to do achieve similar goals. The evaluation modules in particular are well-thought out and follow standards which are being pursued by the community.
While there are comparisons to other frameworks, it is not clear that all of the comparisons are up-to-date and this is a major issue. In particular SB3 does support parallel learning and hardware acceleration and while it doesn't natively support model deployment, it is explained in the documentation how to export models. With a user base of over 3k users, it clearly has a lot of momentum within the community, and so the authors would have to make a strong case that their system is genuinely su
* The idea of a modular RL framework is neat. * The framework has implementations for many well-known algorithms. * Using a Datahub is a great idea (as also shown by SB3 and CleanRL)
* The work does not present novel ideas * The paper does not show any experiments showing the advantage of a modular framework. Neither are any experiments included that would show why one should prefer RLLTE over something like SB3. * I don’t see how “RLLTE decouples RL algorithms from the exploitation-exploration perspective”. This claim seems wholly false. * The work states multiple times that RLLTE is open-source or even ultra-open, but no link to code is given nor is a supplementary archiv
