LFM2.5-2.6B-GGUF

LFM2.5-2.6B GGUF

Community-made GGUF conversions and quantizations of LFM2.5-2.6B, intended for local inference with GGUF-compatible software.

The original model was converted from its Hugging Face / SafeTensors distribution to GGUF using tools provided by llama.cpp.

This is an unofficial community conversion.

The LFM2.5-2.6B model, architecture, and original weights were developed and released by Liquid AI. This repository provides converted and quantized GGUF files derived from the original model.

Original Model

Available GGUF Files

This repository provides the original BF16 GGUF conversion alongside several quantized variants:

Actual memory consumption may be higher than the GGUF file size and depends on factors such as context length, KV cache configuration, inference backend, GPU offloading, and runtime settings.

Conversion Pipeline

The files in this repository were produced using a workflow based on llama.cpp:

LFM2.5-2.6B
      │
      │ SafeTensors
      ▼
convert_hf_to_gguf.py
      │
      ▼
   BF16 GGUF
      │
      │ llama-quantize
      ▼
┌────────┬────────┬───────┬──────┐
│Q4_K_M  │Q5_K_M  │ Q6_K  │ Q8_0 │
└────────┴────────┴───────┴──────┘

No additional training or fine-tuning is performed as part of this conversion process.

Quantization changes the numerical representation of the model weights to reduce storage and memory requirements and may affect model quality.

Usage

These GGUF files are intended for applications and inference engines with compatible GGUF support, particularly llama.cpp and software built around it.

Example with llama.cpp:

llama-cli \
  -m LFM2.5-2.6B-Q5_K_M.gguf \
  -p "Explain how GGUF quantization works."

Runtime parameters should be adjusted according to your hardware, available memory, desired context length, and inference backend.

Compatibility

GGUF compatibility depends on the version of llama.cpp and its support for the underlying LFM architecture.

Because both llama.cpp and GGUF continue to evolve, older inference engines may not correctly load files produced by newer versions.

If you encounter GGUF compatibility problems, first test with a recent version of llama.cpp or your preferred GGUF-compatible runtime.

Reproducibility

The conversion process follows the standard Hugging Face / SafeTensors → GGUF workflow provided by llama.cpp.

The general process consists of:

1. obtaining the original LiquidAI/LFM2.5-2.6B SafeTensors model;
2. converting the model to GGUF using convert_hf_to_gguf.py;
3. retaining the resulting BF16 GGUF;
4. quantizing the BF16 GGUF using llama-quantize;
5. producing the Q4_K_M, Q5_K_M, Q6_K, and Q8_0 variants.

Conversion and quantization behavior may vary between llama.cpp revisions as model architecture support and GGUF tooling evolve.

llama.cpp

GGUF conversion and quantization are performed using tools from the open-source llama.cpp project.

This workflow relies on tooling including:

• convert_hf_to_gguf.py
• llama-quantize
• GGUF infrastructure provided by the project
