grammar : coalesce find + insert into a single insert and adjust move/copy mechanics (#26885)
1) Combine two consecutive lookups (find + insert) into a single insert-attempt/lookup routine so that we don't per
form two O(log(n)) lookup operations in a row anymore -- we only need to do it once and then see if the insert succeeded.
2) Instead of copying every potential stack (expensive) and then moving it (cheap) to new_stacks when it's a final output state, we switch the order so that we move every potential stack (cheap), and then only copy it (expensive) to new stacks when it's a final output state. There are a LOT of intermediate states that get generated, and unless they become final output states, then all of these expensive intermediate copies are wasted.

Before: lookup -> lookup/insert + copy -> optional move to output
New: lookup/insert + move -> optional copy to output

Quick start

A few options to get llama.cpp installed on your machine:

Once installed:

# Download and run a model directly from Hugging Face
llama cli -hf ggml-org/Qwen3.5-0.8B-GGUF

# Launch OpenAI-compatible API server
llama serve -hf ggml-org/Qwen3.5-0.8B-GGUF
VLM session with `llama cli` VLM session with llama cli Built-in web UI against `llama serve` running Qwen 3.6 Built-in web UI against llama serve

Description

The main goal of llama.cpp is to enable LLM (and VLM) inference with minimal setup and state-of-the-art performance on a wide range of hardware - locally and in the cloud.

  • Plain C/C++ implementation without any dependencies
  • Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks
  • AVX, AVX2, AVX512 and AMX support for x86 architectures
  • RVV, ZVFH, ZFH, ZICBOP and ZIHINTPAUSE support for RISC-V architectures
  • 1.5-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, and 8-bit integer quantization for faster inference and reduced memory use
  • Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP and Moore Threads GPUs via MUSA)
  • Vulkan and SYCL backend support
  • CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity

The llama.cpp project is build on top of the ggml library.
