Liquid LFM2.5-8B-A1B GGUF — Quantized by BatiAI

BatiFlow

Quantizations of Liquid AI LFM2.5-8B-A1B (8.3B total / 1.5B active MoE, reasoning + tool calling) for on-device AI on Mac. Built and verified by BatiAI for BatiFlow.

Why LFM2.5-8B-A1B?

8.3B total, only 1.5B active — MoE (32 experts, 4 active) gives 8B-class quality at ~1.5B-class speed
Hybrid architecture — 24 layers: 18 double-gated LIV convolution + 6 GQA attention. Built for edge, not GPUs
Reasoning model — explicit chain-of-thought before the final answer
Native tool calling — Pythonic or JSON function calls (<|tool_call_start|> / <|tool_call_end|>)
128K context, 38T-token training budget, 128K vocab (better non-Latin tokenization incl. Korean)
Blazing on-device — Liquid reports 253 tok/s on M5 Max, 146 tok/s on Ryzen AI Max+ 395, all under 6GB
Released May 28, 2026

Available Quantizations

Quant	Size	Recommended For
Q2_K_S	~2.8 GB	8GB Mac, ultra-compact (imatrix)
IQ3_XXS	~3.2 GB	imatrix, smallest K-class footprint
Q3_K_M	~3.9 GB	8GB+ Mac, balanced
IQ4_XS	~4.3 GB	imatrix, best size/quality
Q4_K_M	~4.9 GB	16GB Mac (recommended)
Q6_K	~6.5 GB	near-original quality

Mac note on Q3_K_M: in every model we've benchmarked on Apple Silicon, Q3_K_M generated slower than Q4_K_M despite the smaller file — Granite 4.1 (+27%), Gemma 4 26B (+12%), Qwen3.8‑27B (+18%), Qwen3.6‑27B (+8%), on both M4 Max and M4 mini. Metal's Q3_K path is limited by dequantization compute rather than bandwidth. We have not measured this particular model's Q3/Q4 pair yet, so treat it as a strong prior, not a measurement: if Q4_K_M fits, take it. On CUDA the two are effectively tied, so this applies to Macs only.

Lower quants (IQ3_XXS, Q2_K_S) and imatrix variants are not provided in the official Liquid GGUF repo — BatiAI adds them for 8GB Macs and tighter footprints.

RAM Requirements

This model is tiny in active params — even the largest quant fits comfortably on 16GB. With only 1.5B active params, throughput stays high regardless of quant.
