llama7b-finetuned-openie-lora

This repository is a legacy Portuguese generative Open Information Extraction (OpenIE) artifact. Despite the suffix -lora, it does not contain a small LoRA adapter: it publishes a complete causal language model in two PyTorch weight shards totaling about 13.48 GB. Download and memory requirements are therefore those of a full 7B-class model.

The published configuration identifies NousResearch/Llama-2-7b-hf and LlamaForCausalLM, while the thesis footnote for the later LLaMA-3-8B-FT (PortOIE-Llama3) points to this URL. Those identities conflict. The public files do not establish that this Llama-2-configured artifact is the Llama 3 model evaluated in the thesis. It is documented here conservatively as a legacy experimental checkpoint; no Llama 3 metric is assigned to it.

Model details

Prompt provenance

The associated local fine-tuned Llama runner uses this exact system instruction:

Dada uma frase S você consegue fazer extrações no formato ARG0 , V, ARG1. Realize a extração para a frase abaixo:

and a user payload beginning with S:. Its historical f-string rendered the Python field name as well (S: sentence.phrase='…'), which is an implementation quirk, not a recommended public interface. Use the normalized form S: {sentence} below.

The thesis records a different Alpaca training instruction:

Dada uma sentença S, você faz extrações no formato ARG0, V, ARG1. Realize a extração para a sentença abaixo:

Because the Llama-2/Llama-3 repository identity and exact checkpoint template are not reconciled, users should test both provenance records before relying on this legacy artifact. The first form is the maintained library's current Llama inference prompt.

Direct Transformers use

This legacy repository is not registered by portuguese-openie. It can be inspected or run directly with Transformers, subject to license clarification:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "bratao/llama7b-finetuned-openie-lora"
revision = "2d5d362dd0ad5ca01b943691e1f494aef1c88c97"
tokenizer = AutoTokenizer.from_pretrained(model_id, revision=revision)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    revision=revision,
    dtype="auto",
    device_map="auto",
    low_cpu_mem_usage=True,
)

sentence = "A UFBA está localizada em Salvador."
instruction = (
    "Dada uma frase S você consegue fazer extrações no formato ARG0 , V, ARG1. "
    "Realize a extração para a frase abaixo:"
)
prompt = f"{instruction}\nS: {sentence}\n"
inputs = tokenizer(prompt, return_tensors="pt", truncation=True).to(model.device)
with torch.inference_mode():
    output = model.generate(
        **inputs,
        max_new_tokens=256,
        do_sample=False,
        pad_token_id=tokenizer.eos_token_id,
    )
generated = output[0, inputs["input_ids"].shape[-1]:]
print(tokenizer.decode(generated, skip_special_tokens=True))

Illustrative target format (not a recorded output for the audited revision):

Extração 0:
ARG0="A UFBA"
V="está localizada em"
ARG1="Salvador"

Evaluation and status

No quantitative metric can be safely attached to these exact public bytes. A local 2023 evaluation artifact associated by date and name with the legacy Llama 2 line reports perfect-match precision/recall/F1 of 0.1500/0.1103/0.1271 and lexical precision/recall/F1 of 0.2800/0.2059/0.2373, but there is no checkpoint checksum in that result. Treat the values as historical leads, not verified repository metrics.

Separately, the thesis reports PortOIE-Llama3 perfect-match F1 0.1290 and lexical F1 0.2446, but its footnote points here while this repository's configuration is Llama 2. Those values belong to the thesis's Llama 3 system description, not this repo.

Training-data provenance

For the Llama 3 fine-tuning experiment, the thesis reports a shuffled mixture of OIEC-PT Silver, Pragmático, Gamalho, and synthetic WikiPUD-Portuguese examples, trained with Axolotl on an NVIDIA H100. Because this artifact's model-family identity conflicts with that record, the mixture cannot be asserted as the training data of these exact bytes. No public dataset identifier is declared; YAML omits datasets.

Requirements and hardware

• Recent Python, PyTorch, Transformers, and Accelerate.
• Download is about 13.48 GB. Unquantized execution generally needs at least 16 GB of free VRAM plus runtime overhead, or CPU/RAM offload. This is an estimate, not a guaranteed minimum.
• The repository contains legacy PyTorch .bin shards, so loading can use more host memory than modern memory-mapped safetensors.

Limitations

• Model identity, exact prompt template, training completion, and evaluation linkage require reconciliation.
• Output may be malformed, incomplete, duplicated, or hallucinated. Verify every supposedly extractive field against the source sentence.
• There is no public domain, bias, safety, or long-context evaluation for these bytes.
• Do not treat generated extractions as verified facts or use them alone for high-impact decisions.

License

No license is declared in the public repository as of 2026-08-30. The repository name and public availability do not grant redistribution rights. Consult the author and the terms of the configured Llama 2 base before downloading, modifying, or redistributing the full weights. This card does not infer a license.
