Optimized for fast inference on Mac devices using the MLX framework. |\n\nWe recommend using it for agentic tasks, data extraction, and RAG. It is not recommended for knowledge-intensive tasks and programming.\n\n### Chat Template\n\nLFM2.5 uses a ChatML-like format. See the [Chat Template documentation](https://docs.liquid.ai/lfm/key-concepts/chat-template) for details. Example:\n\n```\n<|startoftext|><|im_start|>system\nYou are a helpful assistant trained by Liquid AI.<|im_end|>\n<|im_start|>user\nWhat is C. elegans?<|im_end|>\n<|im_start|>assistant\n```\n\nYou can use [`tokenizer.apply_chat_template()`](https://huggingface.co/docs/transformers/en/chat_templating#using-applychattemplate) to format your messages automatically.\n\n### Tool Use\n\nLFM2.5 supports function calling as follows:\n\n1. **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.\n2. **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.\n3. **Function execution**: The function call is executed, and the result is returned as a \"tool\" role.\n4. **Final answer**: LFM2 interprets the outcome of the function call to address the original user prompt in plain text.\n\nSee the [Tool Use documentation](https://docs.liquid.ai/lfm/key-concepts/tool-use) for the full guide. Example:\n\n```\n<|startoftext|><|im_start|>system\nList 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|>\n<|im_start|>user\nWhat is the current status of candidate ID 12345?<|im_end|>\n<|im_start|>assistant\n<|tool_call_start|>[get_candidate_status(candidate_id=\"12345\")]<|tool_call_end|>Checking the current status of candidate ID 12345.<|im_end|>\n<|im_start|>tool\n[{\"candidate_id\": \"12345\", \"status\": \"Interview Scheduled\", \"position\": \"Clinical Research Associate\", \"date\": \"2023-11-20\"}]<|im_end|>\n<|im_start|>assistant\nThe 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|>\n```\n\n## 🏃 Inference\n\nLFM2.5 is supported by many inference frameworks.

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. \n\nBased on the same methodology, we report the average score and standard deviation across five runs with `temperature=0.6` for thinking models. For instruct models, we report scores using greedy decoding.\n\n### Response length\n\nIn comparison with Qwen3-1.7B (thinking mode), it requires fewer output tokens while offering higher overall performance.\n\n![LFM2.5-1.2B - Average Response Length](https://cdn-uploads.huggingface.co/production/uploads/61b8e2ba285851687028d395/Gcq_HUYLVC779xOuut2EI.png)\n\n### Inference speed\n\nLFM2.5-1.2B-Thinking offers extremely fast inference speed on CPUs with a low memory profile compared to similar-sized models.\n\n![LFM2.5-1.2B - Inference Performance](https://cdn-uploads.huggingface.co/production/uploads/61b8e2ba285851687028d395/4ODY8nGws22vICfcMTxNx.png)\n\nIn addition, we are partnering with AMD, Qualcomm, Nexa AI, and FastFlowLM to bring the LFM2.5 family to NPUs. These optimized models are available through our partners, enabling highly efficient on-device inference.\n\nWe report the following numbers with 1K prefill and 100 decode tokens: \n\n| Device                                               | Inference | Framework        | Model                | Prefill (tok/s) | Decode (tok/s) | Memory |\n| ---------------------------------------------------- | --------- | ---------------- | -------------------- | --------------- | -------------- | ------ |\n| AMD Ryzen AI 395+                                    | NPU       | FastFlowLM       | LFM2.5-1.2B-Thinking | 1487            | 60             | 1600MB (full context) |\n| AMD Ryzen AI 9 HX 370                                | NPU       | FastFlowLM       | LFM2.5-1.2B-Thinking | 1487            | 57             | 1600MB (full context) |\n| AMD Ryzen AI 9 HX 370                                | CPU       | llama.cpp (Q4_0) | LFM2.5-1.2B-Thinking | 2975            | 116            | 856MB  |\n| Qualcomm Snapdragon® X Elite                         | NPU       | NexaML           | LFM2.5-1.2B-Thinking | 2591            | 63             | 0.9GB  |\n| Qualcomm Snapdragon® Gen4 (ROG Phone9 Pro)           | NPU       | NexaML           | LFM2.5-1.2B-Thinking | 4391            | 82             | 0.9GB  |\n| Qualcomm Dragonwing IQ9 (IQ-9075) (IoT)              | NPU       | NexaML           | LFM2.5-1.2B-Thinking | 2143            | 53             | 0.9 GB |\n| Qualcomm Snapdragon® Gen4 (Samsung Galaxy S25 Ultra) | CPU       | llama.cpp (Q4_0) | LFM2.5-1.2B-Thinking | 335             | 70             | 719MB  |\n\n**LFM2.5-1.2B-Thinking excels at long-context inference.** For example, on AMD Ryzen™ NPUs with FastFlowLM, decoding throughput sustains ~52 tok/s at 16K context and ~46 tok/s even at the full 32K context, indicating robust long-context scalability. For more details on longer context benchmarks on AMD Ryzen™ NPUs with FastFlowLM, please review these [here](https://fastflowlm.com/docs/benchmarks/lfm2_results/).\n\nThese capabilities unlock new deployment scenarios across various devices, including vehicles, mobile devices, laptops, IoT devices, and embedded systems.\n\n## Contact\n\nFor enterprise solutions and edge deployment, contact [sales@liquid.ai](mailto:sales@liquid.ai).\n\n## Citation\n\n```bibtex\n@article{liquidAI2026thinking,\n  author = {Liquid AI},\n  title = {LFM2.5-1.2B-Thinking: On-Device Reasoning Under 1GB},\n  journal = {Liquid AI Blog},\n  year = {2026},\n  note = {www.liquid.ai/blog/lfm2-5-1-2b-thinking-on-device-reasoning-under-1gb},\n}\n```\n\n```bibtex\n@article{liquidai2025lfm2,\n  title={LFM2 Technical Report},\n  author={Liquid AI},\n  journal={arXiv preprint arXiv:2511.23404},\n  year={2025}\n}\n```",
