Verifiers Tool Library Overview
Verifiers is a modular library of tools specifically designed for building reinforcement learning (RL) environments and training large language model (LLM) agents. It consists of a set of well-designed components designed to provide developers with a stable and reliable development foundation.
core functionality
- Environment Building Blocks: Provides a variety of standardized environmental templates
- Training tools: Includes GRPOTrainer
- Evaluation systems: Integration of a flexible scoring mechanism
- Utilities: Provides CLI commands to streamline workflow
Technical characteristics
Verifiers employs a transformers Trainer architecture to realize asynchronous GRPO training and supports vLLM inference backend. It works with the prime-rl project to enable large-scale FSDP training. This toolbase specifically addresses the common problem of "codebase forking" in RL infrastructures, providing a unified workbase for researchers and developers.
