June 2025 monthly summary: Delivered essential multiturn tokenization improvements and RL readiness across two repositories, focusing on documentation, testing, and model-agnostic tokenization. This includes VeRL multiturn tokenization documentation with a fixed-base incremental solution, SGLang multi-turn tokenization refactor with template-aware masking, and a fix to the SGLang tool call parser to enable multiturn RL experiments with recent updates. The work enhances training/inference consistency, accelerates onboarding, and strengthens configuration/testing practices for Qwen2.5-3B and Qwen3-4B deployments.
