llama.cpp v0.6.0 ships GLM-5.3-Flash (320B) and Qwen4Exp MTP speculative decoding, a new llama_batch_ext API, and up to ~3x faster few-row mat-mul on Apple GPUs

ggml-org released llama.cpp v0.6.0 on Oct 5 (v0.5.0 was Sep 23). It brings GLM-5.3-Flash (GLM5-Next, a 320B text+vision hybrid MoE) into a stable tag, adds MTP speculative decoding for Qwen4Exp (~1.5x decode on DGX Spark), introduces the llama_batch_ext / llama_process() API for mixed token and embedding batches, adds few-row MMA mat-mul kernels on Metal (up to ~3x for speculative and batched decoding), and bumps ggml to v0.26.0. Session file formats are bumped too.

Key Takeaways

  • New models: GLM-5.3-Flash (GLM5-Next, 320B KDA/DSA hybrid text+vision MoE), Clef decision model, Ling 3.0 VL, LFM2.5-Encoder
  • Speed: Qwen4Exp MTP speculative decoding ~1.5x decode on DGX Spark; Metal few-row MMA mat-mul up to ~3x
  • API: llama_batch_ext + llama_process() for mixed token/embedding batches; server and examples migrated
  • Compat: LLAMA_SESSION_VERSION 11 and LLAMA_STATE_SEQ_VERSION 4, so old session/state files must be regenerated
  • Server: /v1/models reports modalities, /v1/embeddings takes typed vision/audio/video input, new /v1/systemone endpoint

llama.cpp ships Decision Models: /v1/systemone scores options in one forward pass (Julia-1, Laya, Kev-4B, lev, OpenJev)

On 2026-10-02 ggml-org announced llama.cpp server support for Decision Models via /v1/systemone (PR #29818, merged 2026-10-02T09:56Z). Send a state plus typed questions; get option probabilities in one forward pass. Day-0 models: Julia-1, Laya, Kev-4B, lev, OpenJev (vision). Cloudflare Clef is planned next.

Key Takeaways

  • Official post 2026-10-02 + merged PR #29818 (2026-10-02T09:56Z, +2139/−15)
  • Endpoint POST /v1/systemone with choice/score/noul; probabilities + confidence; output_tokens=0
  • Day-0 GGUFs: Julia-1 / Laya / Kev-4B / lev / OpenJev; median ~3–43 ms/question on RTX PRO 6000 (blog table)
  • Distinct from Ollama SystemOne & Cloudflare Clef hosting; Clef listed as next in llama.cpp
  • Start: llama serve -hf ggml-org/Kev-4B-GGUF then curl /v1/systemone
