LFM2.5-1.2B-Instruct
LFM2.5 is a new family of hybrid models designed for on-device deployment. It builds on the LFM2 architecture with extended pre-training and reinforcement learning.

🏃 How to run LFM2.5
Example usage with llama.cpp:
llama-cli -hf LiquidAI/LFM2.5-1.2B-Instruct-GGUF --conversation \
--temp 0.1 --top-k 50 --repeat-penalty 1.05
QAD Q4_0 GGUF
The Quantization-Aware Distillation (QAD) checkpoint is available as
LFM2.5-1.2B-Instruct-QAD-Q4_0.gguf.
This is distinct from the post-training-quantized LFM2.5-1.2B-Instruct-Q4_0.gguf;
both use the GGUF Q4_0 format.
Example usage with llama.cpp:
llama-cli -hf LiquidAI/LFM2.5-1.2B-Instruct-GGUF \
--hf-file LFM2.5-1.2B-Instruct-QAD-Q4_0.gguf \
-p "What is C. elegans?"
QAD source weights (safetensors)
The original FP32 QAD source checkpoint is available in
qad/, with its model config,
tokenizer, generation defaults, and the same chat template as the released QAD GGUF.
It can be loaded in Transformers by passing subfolder="qad":
from transformers import AutoModelForCausalLM, AutoTokenizer
repo_id = "LiquidAI/LFM2.5-1.2B-Instruct-GGUF"
tokenizer = AutoTokenizer.from_pretrained(repo_id, subfolder="qad")
model = AutoModelForCausalLM.from_pretrained(
repo_id, subfolder="qad", dtype="auto", device_map="auto"
)
inputs = tokenizer.apply_chat_template(
[{"role": "user", "content": "What is 2 + 2?"}],
tokenize=True, add_generation_prompt=True, return_dict=True, return_tensors="pt",
).to(model.device)
outputs = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(outputs[0, inputs["input_ids"].shape[-1]:], skip_special_tokens=True))
These weights are intended for fine-tuning and experimentation. Published QAD results apply to the Q4_0 GGUF; direct FP32/BF16 inference and other quantization formats may behave differently. See the source checkpoint documentation for validation details and the license.
