GLM4.7-Distill-LFM2.5-1.2B

Model Overview

GLM4.7-Distill-LFM2.5-1.2B is a 1.2B-parameter instruction-following language model obtained via offline distillation from GLM-4.7 into the Liquid AI LFM2 architecture.

The model is designed to be:

• concise and non-verbose
• strong at instruction following
• efficient for local and edge deployments
• suitable for assistant, agentic, and system-integration use cases

This model does not include chain-of-thought reasoning and is optimized for final-answer quality rather than verbose explanations.

Key Characteristics

• Base architecture: Liquid AI LFM2
• Model size: 1.2B parameters
• Training method: Offline supervised distillation (SFT with LoRA)
• Teacher model: GLM-4.7 (used only for data generation)
• Inference dependency on teacher: None
• Reasoning traces: Not included
• Target behavior: Clear, grounded, instruction-aligned responses

Training Details

Distillation Approach

This model was trained using offline distillation, where instruction-response pairs generated by GLM-4.7 were combined with high-quality public instruction datasets.

The teacher model was not used during training or inference, and no teacher weights or logits are included.

Training focused on:

• instruction adherence
• response clarity
• reduced verbosity
• stable decision boundaries

Datasets Used (Approx. 13K Samples)

The following datasets were sampled and combined:

• Open-Orca / FLAN
• Databricks Dolly 15K
• OpenAssistant OASST1
• BAAI Infinity-Instruct
• CodeAlpaca
• TIGER-Lab MathInstruct

These were augmented with GLM-4.7–generated instruction responses, with explicit avoidance of chain-of-thought reasoning.

---

Intended Use

This model is well suited for:

• general-purpose assistants
• planning and task decomposition
• summarization and explanation
• lightweight coding assistance
• agentic workflows
• system integration and automation
• on-device or edge inference scenarios

---

Limitations

Like other compact distilled models, this model may:

• hallucinate when given insufficient or false premises
• struggle with adversarial logical inference (NLI-style tasks)
• lack temporal awareness of recent events
• provide confident answers where explicit uncertainty is required

For critical reasoning, verification layers or external tools are recommended.

---

Ethical & Responsible Use

• This model was trained on a mixture of public datasets and synthetic data.
• It does not contain personal data by design.
• Outputs should not be treated as authoritative in medical, legal, or safety-critical contexts.

streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)

prompt = "Implement QuickSort algorithm with complexity analysis"

input_ids = tokenizer.apply_chat_template(
    [{"role": "user", "content": prompt}],
    add_generation_prompt=True,
    return_tensors="pt",
    tokenize=True,
).to(model.device)
