# Model Card for b1ade-1b


Instruction fine tuned 1B parameter model; pass in:

1. `context: <...>`
2. `question: <...>`

  and expect an `answer: <...>`

See implemetation example below (also see https://huggingface.co/spaces/w601sxs/b1ade-1b):

```
import torch
import transformers
import os, time
import tempfile
from transformers import AutoTokenizer, AutoModelForCausalLM


BASE_MODEL = "w601sxs/b1ade-1b-bf16"

tokenizer = AutoTokenizer.from_pretrained(BASE_MODEL)
    

model = AutoModelForCausalLM.from_pretrained(BASE_MODEL, 
                                             torch_dtype=torch.bfloat16,
                                             device_map="auto",
                                             offload_folder="offload")


model.eval()

        return False

        out_text = tokenizer.batch_decode(outputs.detach().cpu().numpy(), skip_special_tokens=True)[0].split("answer:")[-1]
    
    return print(out_text.split(text)[-1])



predict("context: <The center contact of the bulb typically connects to the medium-power filament, and the ring connects to the low-power filament. Thus, if a 3-way bulb is screwed into a standard light socket that has only a center contact, only the medium-power filament operates. In the case of the 50 W / 100 W / 150 W bulb, putting this bulb in a regular lamp socket will result in it behaving like a normal 100W bulb.>\n question: <Question: Do 3 way light bulbs work in any lamp?>\n")
