July 2025 (2025-07) - Focused on robustness and reliability of the sequence generation path in yhyang201/sglang. Delivered a targeted bug fix for End-of-Sequence (EOS) handling when the EOS token ID is zero, ensuring zero is treated as a valid token ID by keeping eos_ids non-None during sequence generation. This reduces generation errors and improves downstream stability for models relying on sg-lang behavior with EOS represented as 0. The work enhances production reliability and contributes to a more stable modeling pipeline.
