QVAC Genesis II Pretrained Model - Failure Analysis Prompt

Key Highlights

• Pretrained on QVAC Genesis II
  This model has been pretrained on Tether’s QVAC Genesis II dataset.

  Dataset card: https://huggingface.co/datasets/qvac/GenesisII

  The checkpoint uses the Failure Analysis prompt format and was pretrained on approximately 53B tokens, using BF16 mixed precision and a 4,096-token context window, with a Qwen3-family 1.7B-parameter decoder-only transformer architecture.

• Checkpoints in Hugging Face format
  Checkpoints are provided in standard Hugging Face format for inference, continual pretraining, and fine-tuning.

Model Details

Model Description

• Developed by: QVAC by Tether
• Model type: Decoder-only Transformer (causal LM)
• Language(s) (NLP): Primarily English
• License: Apache-2.0
• Finetuned from model: None (randomly initialized)
• Intended stage: Base pretrained model (no SFT / RLHF)

Dataset Details

• Dataset: qvac/GenesisII
• Prompt format: Failure Analysis prompt

---

Uses

Direct Use

• General language modeling: next-token prediction, continuation, summarization, drafting.
• Research baseline for scaling, data ablations, or tokenizer studies.

Downstream Use (recommended)

• Continued Pre-Training (CPT) on more tokens.
• SFT for assistants, domain experts, or task-specific models.
• Preference optimization / RLHF for safer, more helpful behavior.
• Adapters/LoRA for efficient domain specialization.

Out-of-Scope Use

• High-stakes decision-making (medical/financial/legal)
• Safety-critical or autonomous control systems
• Unfiltered end-user deployment without alignment / safety layers
• Any use that violates applicable laws or platform policies.

Bias, Risks, and Limitations

• Bias & toxicity: May reflect or amplify biases present in web text.
• Hallucinations: Can produce confident but incorrect statements or citations.
• Security / privacy: May emit continuous random strings.
• Context limit: 4,096 tokens; longer inputs require chunking.

Recommendations

• Disclose limitations to downstream users.
• Research model: not intended for production use cases.

How to Get Started

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "qvac/genesis-ii-model-failure-analysis"

tok = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

prompt = "Explain Newton's laws of motion."
inputs = tok(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=256, do_sample=True, top_p=0.9, temperature=0.7)
print(tok.decode(out[0], skip_special_tokens=True))
