Model Card for Jay24-AI/bloom-7b1-lora-tagger

This model is a LoRA fine-tuned version of BigScience’s BLOOM-7B1 model, trained on a dataset of English quotes. The goal was to adapt BLOOM using the PEFT (Parameter-Efficient Fine-Tuning) approach with LoRA, making it lightweight to train and efficient for deployment.

Model Details

Model Description

  • Developed by: Jay24-AI
  • Funded by [optional]: N/A
  • Shared by [optional]: Jay24-AI
  • Model type: Causal Language Model with LoRA adapters
  • Language(s): English
  • License: Apache-2.0 (inherited from bigscience/bloom-7b1; LoRA adapters are MIT-compatible)
  • Finetuned from model: bigscience/bloom-7b1

Model Sources

Uses

Direct Use

The model can be used for text generation and tagging based on quote-like prompts. For example, you can input a quote, and the model will generate descriptive tags.

Downstream Use

  • Can be further fine-tuned on custom tagging or classification datasets.
  • Could be integrated into applications that require lightweight quote classification, text annotation, or prompt-based generation.

Out-of-Scope Use

  • Not suitable for factual question answering.
  • Not designed for sensitive or high-stakes decision-making (e.g., medical, legal, or financial advice).

Bias, Risks, and Limitations

  • Inherits limitations and biases from BLOOM-7B1 (trained on large-scale internet data).
  • The fine-tuned dataset (Abirate/english_quotes) is relatively small, so the model may overfit and generalize poorly outside similar data.
  • Risk of generating irrelevant or biased tags if prompted outside the intended scope.
  • Limited training (50 steps) may result in suboptimal performance.

Recommendations

Users should:

  • Validate outputs before production use.
  • Avoid relying on the model for critical applications.

How to Get Started with the Model 

import torch
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM, AutoTokenizer

peft_model_id = "Jay24-AI/bloom-7b1-lora-tagger"
config = PeftConfig.from_pretrained(peft_model_id)
model = AutoModelForCausalLM.from_pretrained(config.base_model_name_or_path, return_dict=True, load_in_8bit=True, device_map='auto')
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)

# Load the Lora model
model = PeftModel.from_pretrained(model, peft_model_id)

batch = tokenizer("“The only way to do great work is to love what you do.” ->: ", return_tensors='pt')

with torch.cuda.amp.autocast():
  output_tokens = model.generate(**batch, max_new_tokens=50)

print('\n\n', tokenizer.decode(output_tokens[0], skip_special_tokens=True))

Training Details

Training Data

  • Dataset used: Abirate/english_quotes
  • Subset: Entire training split (exact size not specified in script).
  • Structure: Each entry includes a quote and its corresponding tags.
  • Preprocessing:
    • Combined the quote and tags into a single text string: <quote> ->: <tags>
    • Tokenized using the AutoTokenizer from bigscience/bloom-7b1.
    • Applied batching via Hugging Face datasets.map with batched=True.

Training Procedure

Preprocessing

  • Converted text examples into the "quote ->: tags" format.
  • Tokenized using Bloom’s tokenizer with default settings.
  • Applied DataCollatorForLanguageModeling with mlm=False (causal LM objective).

Training Hyperparameters

  • Base model: bigscience/bloom-7b1
  • Adapter method: LoRA via PEFT
  • LoRA configuration:
    • r: 8
    • lora_alpha: 16
    • lora_dropout: 0.05
    • bias: "none"
    • task_type: "CAUSAL_LM"
  • TrainingArguments:
    • per_device_train_batch_size: 2
    • gradient_accumulation_steps: 2
    • warmup_steps: 100
    • max_steps: 50
    • learning_rate: 2e-4
    • fp16: True
    • logging_steps: 1
    • output_dir: outputs/
  • Precision regime: Mixed precision (fp16) with 8-bit quantization via bitsandbytes.
  • Caching: model.config.use_cache = False during training to suppress warnings.
  • Additional Settings:
    • Original model weights frozen; small parameters (e.g., layer normalization) cast to FP32 for stability.
    • Gradient checkpointing enabled to reduce memory usage.
    • lm_head modified to output FP32 for stability.

Speeds, Sizes, Times

  • Trainable parameters: LoRA adapters only (~0.1% of BLOOM-7B1’s ~7.1 billion parameters, exact count printed via print_trainable_parameters).
  • Approx. size: Much smaller than 7B full checkpoint since only adapters are stored.
  • Max steps: 50 (~100 updates with gradient accumulation).
  • Training runtime: Not logged in script; depends on GPU.
  • Batch size effective: 4 (2 × accumulation steps of 2).

Compute Infrastructure

  • Hardware: Single CUDA GPU (set with os.environ["CUDA_VISIBLE_DEVICES"]="0"; specific GPU model not specified, e.g., A100, T4, V100).
  • Software:
    • PyTorch
    • Hugging Face Transformers (main branch from GitHub)
    • Hugging Face PEFT (main branch from GitHub)
    • Hugging Face Datasets
    • Accelerate
    • Bitsandbytes (for 8-bit quantization)
  • Gradient checkpointing: Enabled to save memory.
  • Mixed precision: Enabled with fp16.
