June 2026: Delivered unified Efficient Inference Cache (EIC) management and HiCache integration for bytedance-iaas/sglang, driving memory efficiency and improved request handling. Implemented API routes to enable/disable EIC cache, introduced an EIC cache controller and chunk cache to optimize memory usage, and integrated EIC cache with the scheduler to streamline inference workloads. Enhanced HiCache with device-host write/load capabilities to boost EIC performance. Addressed cache-path reliability with targeted fixes. These changes align with ongoing ep_main updates and fixes identified in commits c8c09e432314b2f68e4d48baa6298b1bfa875fbe and 472976dfd2d1d9b1c7fb9afa6a0456e2bdafac7f, reflecting collaboration and code quality improvements across the month.

December 2025 (2025-12) summary for kvcache-ai/sglang. Focused on reliability hardening through a targeted bug fix in logprob token handling. Implemented clamping for logprob token IDs to adhere to the model vocabulary size, preventing out-of-range errors during token processing and inference. This reduces runtime exceptions and improves stability across edge inputs, supporting safer production deployments.
