Model Card

Model Summary

This model is a LoRA fine-tuned variant of huggingface/your-base-model, trained using the Unsloth library for parameter-efficient fine-tuning (PEFT). It supports efficient training and inference with significantly reduced VRAM usage while maintaining high performance.

• Base model: huggingface/your-base-model
• Fine-tuning method: LoRA (rank = 8, alpha = 16)
• Framework: Hugging Face Transformers + Unsloth
• Intended use: Instruction-following and text generation tasks

---

Training Details

• Optimizer: AdamW

• LoRA Config:

  • Rank: 8
  • Alpha: 16
  • Dropout: 0.0

• Target modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj

• Gradient checkpointing: Enabled (unsloth mode, reduces VRAM by ~30%)

---

Datasets

• Primary dataset: HuggingFaceH4/Multilingual-Thinking
• Data type: instruction–response pairs

Intended Use

This model is suitable for:

• Text generation
• Instruction-following tasks
• Educational, research, or prototyping purposes

⚠️ Not intended for unsafe or malicious content generation.

---

Limitations

• Performance depends on the quality and size of the fine-tuning dataset.
• May produce hallucinations on knowledge-intensive queries.
• English-focused (if dataset was English).

How to Use

[NOTE] Currently finetunes can only be loaded via Unsloth in the meantime - we're working on vLLM and GGUF exporting!

if False:
    from unsloth import FastLanguageModel
    model, tokenizer = FastLanguageModel.from_pretrained(
        model_name = "dexyasir/gpt-oss-20b-Multilingual-Thinking-finetuned", # YOUR MODEL YOU USED FOR TRAINING
        max_seq_length = 1024,
        dtype = None,
        load_in_4bit = True,
    )

messages = [
    {"role": "system", "content": "reasoning language: French\n\nYou are a helpful assistant that can solve mathematical problems."},
    {"role": "user", "content": "Solve x^5 + 3x^4 - 10 = 3."},
]
inputs = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt = True,
    return_tensors = "pt",
    return_dict = True,
    reasoning_effort = "high",
).to(model.device)
from transformers import TextStreamer
_ = model.generate(**inputs, max_new_tokens = 64, streamer = TextStreamer(tokenizer))
