# 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.
|
||||||
|
|
||||||
|
- **Best-in-class performance**: A 1.2B model rivaling much larger models, bringing high-quality AI to your pocket.
|
||||||
|
- **Fast edge inference**: 239 tok/s decode on AMD CPU, 82 tok/s on mobile NPU. Runs under 1GB of memory with day-one support for llama.cpp, MLX, and vLLM.
|
||||||
|
- **Scaled training**: Extended pre-training from 10T to 28T tokens and large-scale multi-stage reinforcement learning.
|
||||||
|
|
||||||
|

|
||||||

| Model | Description |
|
||||||
|
|-------|-------------|
|
||||||
|
| [**LFM2.5-1.2B-Instruct**](https://huggingface.co/LiquidAI/LFM2.5-1.2B-Instruct) | Original model checkpoint in native format. Best for fine-tuning or inference with Transformers and vLLM. |

|
||||||
|
|
||||||
|
We recommend using it for agentic tasks, data extraction, and RAG. It is not recommended for knowledge-intensive tasks and programming.
|
||||||
|
|
||||||
|
### Chat Template
|
||||||
|
|
||||||
|
LFM2.5 uses a ChatML-like format. See the [Chat Template documentation](https://docs.liquid.ai/lfm/key-concepts/chat-template) for details. Example:
|
||||||
|
|
||||||
|
```
|
||||||
|
<|startoftext|><|im_start|>system
|
||||||
|
You are a helpful assistant trained by Liquid AI.<|im_end|>
|
||||||
|
<|im_start|>user
|
||||||
|
What is C. elegans?<|im_end|>
|
||||||
|
<|im_start|>assistant
|
||||||
|
```
|
||||||
|
|
||||||
|
You can use [`tokenizer.apply_chat_template()`](https://huggingface.co/docs/transformers/en/chat_templating#using-applychattemplate) to format your messages automatically.
|
||||||
|
|
||||||
|
### Tool Use
|
||||||
|
|
||||||
|
LFM2.5 supports function calling as follows:
|
||||||
|
|
||||||
|
1. **Function definition**: We recommend providing the list of tools as a JSON object in the system prompt. You can also use the [`tokenizer.apply_chat_template()`](https://huggingface.co/docs/transformers/en/chat_extras#passing-tools) function with tools.
|
||||||
|
2. **Function call**: By default, LFM2.5 writes Pythonic function calls (a Python list between `<|tool_call_start|>` and `<|tool_call_end|>` special tokens), as the assistant answer. You can override this behavior by asking the model to output JSON function calls in the system prompt.
|
||||||
|
3. **Function execution**: The function call is executed, and the result is returned as a "tool" role.
|
||||||
|
4. **Final answer**: LFM2 interprets the outcome of the function call to address the original user prompt in plain text.
|
||||||
|
|
||||||
|
See the [Tool Use documentation](https://docs.liquid.ai/lfm/key-concepts/tool-use) for the full guide. Example:
|
||||||
|
|
||||||
|
```
|
||||||
|
<|startoftext|><|im_start|>system
|
||||||
|
List of tools: [{"name": "get_candidate_status", "description": "Retrieves the current status of a candidate in the recruitment process", "parameters": {"type": "object", "properties": {"candidate_id": {"type": "string", "description": "Unique identifier for the candidate"}}, "required": ["candidate_id"]}}]<|im_end|>
|
||||||
|
<|im_start|>user
|
||||||
|
What is the current status of candidate ID 12345?<|im_end|>
|
||||||
|
<|im_start|>assistant
|
||||||
|
<|tool_call_start|>[get_candidate_status(candidate_id="12345")]<|tool_call_end|>Checking the current status of candidate ID 12345.<|im_end|>
|
||||||
|
<|im_start|>tool
|
||||||
|
[{"candidate_id": "12345", "status": "Interview Scheduled", "position": "Clinical Research Associate", "date": "2023-11-20"}]<|im_end|>
|
||||||
|
<|im_start|>assistant
|
||||||
|
The candidate with ID 12345 is currently in the "Interview Scheduled" stage for the position of Clinical Research Associate, with an interview date set for 2023-11-20.<|im_end|>
|
||||||
|
```
|
||||||
|
|
||||||
|

Here's a quick start example with Transformers:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
|
||||||
|
|
||||||
|
model_id = "LiquidAI/LFM2.5-1.2B-Instruct"
|
||||||
|
model = AutoModelForCausalLM.from_pretrained(
|
||||||
|
model_id,
|
||||||
|
device_map="auto",
|
||||||
|
dtype="bfloat16",
|
||||||
|
# attn_implementation="flash_attention_2" <- uncomment on compatible GPU
|
||||||
|
)
|
||||||
|
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||||
|
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)
|
||||||
|
|
||||||
|
prompt = "What is C. elegans?"
|
||||||
|
|
||||||
|
input_ids = tokenizer.apply_chat_template(
|
||||||
|
[{"role": "user", "content": prompt}],
|
||||||
|
add_generation_prompt=True,
|
||||||
|
return_tensors="pt",
|
||||||
|
tokenize=True,
|
||||||
|
).to(model.device)
|
||||||
|
|
||||||
|
output = model.generate(
|
||||||
|
input_ids,
|
||||||
|
do_sample=True,
|
||||||
|
temperature=0.1,
|
||||||
|
top_k=50,
|
||||||
|
top_p=0.1,
|
||||||
|
repetition_penalty=1.05,
|
||||||
|
max_new_tokens=512,
|
||||||
|
streamer=streamer,
|
||||||

)
|
||||||
|
```
|
||||||
|
|
||||||
|

GPQA, MMLU-Pro, IFBench, and AIME25 follow [ArtificialAnalysis's methodology](https://artificialanalysis.ai/methodology/intelligence-benchmarking). For IFEval and Multi-IF, we report the average score across strict and loose prompt and instruction accuracies. For BFCLv3, we report the final weighted average score with a custom Liquid handler to support our tool use template.

### Inference speed
|
||||||
|
|
||||||
|
LFM2.5-1.2B-Instruct offers extremely fast inference speed on CPUs with a low memory profile compared to similar-sized models.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
In addition, we are partnering with AMD, Qualcomm, and Nexa AI to bring the LFM2.5 family to NPUs. These optimized models are available through our partners, enabling highly efficient on-device inference.
|
||||||
|
The following numbers have been calculated using 1K prefill and 100 decode tokens:
|
||||||
|
|
||||||
|
| Device | Inference | Framework | Model | Prefill (tok/s) | Decode (tok/s) | Memory (GB) |

|
||||||
|
| Qualcomm Snapdragon® Gen4 (ROG Phone9 Pro) | NPU | NexaML | LFM2.5-1.2B-Instruct | 4391 | 82 | 0.9GB |
|
||||||
