LLAMA.CPP SHIPS FOUR BUILDS IN 24 HOURS AS VLLM AND SGLANG RACE ON SEQUENCE PARALLELISM
By RepoJournal · Filed · About Local LLMs
The local LLM stack is moving fast: llama.cpp pushed builds b10219-b10223 with reasoning persistence and security updates, while vLLM landed sequence parallelism for DeepSeek V4 and sglang unified its radix cache for multi-turn agentic work.
Llama.cpp released four builds across the briefing window [1] [2] [3] [4], anchored by CLI persistence of reasoning content in chat history [3], which fixes a critical gap: the old code collected reasoning from the stream but only stored assistant messages, so prior thoughts couldn't be re-injected on later turns. In parallel, BoringSSL got bumped to 0.20260730.0 [2], and CI errors were fixed [1]. Over at vLLM, the bigger architectural shift landed: sequence parallelism for DeepSeek V4 using collective ops from Kimi K3, unifying multi-path encoder cuda graphs [5] [6], and a ROCm MLA mask fix [7] to prevent causality leaks in speculative verify blocks. SGLang addressed two config infrastructure debt items [9] [11] and shipped session-reference-aware radix cache [8], which keeps agentic workloads from evicting prefixes still in use by active sessions. Kimi K3 support landed in SGLang with reasoning, tool-calls, and native OpenAI serving [10]. All three repos are consolidating patterns: llama.cpp on reasoning preservation, vLLM on parallelism unification, sglang on config consistency and agentic cache semantics.
