Instructions to use LiquidAI/LFM2.5-8B-A1B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use LiquidAI/LFM2.5-8B-A1B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="LiquidAI/LFM2.5-8B-A1B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("LiquidAI/LFM2.5-8B-A1B")
model = AutoModelForCausalLM.from_pretrained("LiquidAI/LFM2.5-8B-A1B", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Any plans for a LFM3 version of this 8B-A1B model? I'm curious to see improvements to my favorite LiquidAI model.

Hey thanks! What do you think about LFM3-1.7B as a drop-in replacement for the 8B-A1B?

Hey thanks! What do you think about LFM3-1.7B as a drop-in replacement for the 8B-A1B?

Please see my post about sampling parameters.

It would be great if you could run coding benchmarks and select the sampling parameters exclusively for coding instead of combining it with general category.

For coding, it hasn't been great so far though on general tasks, it is punching above its weight class.

@mlabonne , I haven't tested the LFM3-1.7B, but I really liked the LFM3-VL-2B. The LFM3-VL-2B in Q8_0 is 90 tok/s, Q6_K is 122 tok/s, i don't know why Q5_K_M is so slow, only 26 tok/s. Q6_K is my to go quant here.

EDIT:
Well, LFM3-VL-2B is LFM3-1.7B plus vision encoder.
