# Liquid Foundation Models

> Liquid Foundation Models (LFMs) are a new class of multimodal architectures built for fast inference and on-device deployment. Browse all available models and formats here.

<div className="capabilities">
  All of our models share the following capabilities:

  * 32k token context length for extended conversations and document processing
  * Designed for fast inference with [Transformers](/deployment/gpu-inference/transformers), [llama.cpp](/deployment/on-device/llama-cpp), [vLLM](/deployment/gpu-inference/vllm), [MLX](/deployment/on-device/mlx), [Ollama](/deployment/on-device/ollama), and [LEAP](/deployment/on-device/sdk/quick-start)
  * Trainable via SFT, DPO, and GRPO with [TRL](/lfm/fine-tuning/trl) and [Unsloth](/lfm/fine-tuning/unsloth)

## Model Formats

All LFM2 models are available in multiple formats for flexible deployment:

* **GGUF** — Best for local CPU/GPU inference on any platform. Use with [llama.cpp](/deployment/on-device/llama-cpp), [LM Studio](/deployment/on-device/lm-studio), or [Ollama](/deployment/on-device/ollama). Append `-GGUF` to any model name.
* **MLX** — Best for Mac users with Apple Silicon. Leverages unified memory for fast inference via [MLX](/deployment/on-device/mlx). Browse at [mlx-community](https://huggingface.co/mlx-community/collections?search=LFM).
* **ONNX** — Best for production deployments and edge devices. Cross-platform with ONNX Runtime across CPUs, GPUs, and accelerators. Append `-ONNX` to any model name.

### Quantization

Quantization reduces model size and speeds up inference with minimal quality loss. Available options by format:

* **GGUF** — Supports `Q4_0`, `Q4_K_M`, `Q5_K_M`, `Q6_K`, `Q8_0`, `BF16`, and `F16`. `Q4_K_M` offers the best balance of size and quality.
* **MLX** — Available in `3bit`, `4bit`, `5bit`, `6bit`, `8bit`, and `BF16`. `8bit` is recommended.
* **ONNX** — Supports `FP32`, `FP16`, `Q4`, and `Q8` (MoE models also support `Q4F16`). `Q4` is recommended for most deployments.
