Model Card for Asimov-7B-v1

Asimov will be a series of language models that are trained to act as useful writing assistants, named after a biochemist one of the profilic writers of our time Isaac Asimov. Asimov-7B-v1 is the 1st pilot model in the series, and is a fine-tuned version of mistralai/Mistral-7B-v0.1 that was fine-tuned on a filtered, cleaned, variant of Ultrachat. This model has was not aligned with any datasets so consider this as a model with no guard rails.

• Model type: A 7B parameter GPT-like model fine-tuned on publicly available synthetic datasets.

Bias, Risks, and Limitations

Asimov-7B-v1 has not been aligned to human preferences, so the model can produce problematic outputs (especially when prompted to do so). It is also unknown what the size and composition of the corpus was used to train the base model (mistralai/Mistral-7B-v0.1), however it is likely to have included a mix of Web data and technical sources like books and code. See the Falcon 180B model card for an example of this.

How to Get Started with the Model

Use the code below to get started with the model.

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

model_name = "prithivida/Asimov-7B-v1"
peft_config = PeftConfig.from_pretrained(model_name)

base_model = AutoModelForCausalLM.from_pretrained(
        peft_config.base_model_name_or_path,
        return_dict=True,
        device_map="auto",
        torch_dtype=torch.float16,
        low_cpu_mem_usage=True,
)

model = PeftModel.from_pretrained(
        base_model,
        model_name,
        torch_dtype=torch.float16,
        device_map="auto",
)

tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=True)
model.config.pad_token_id = tokenizer.unk_token_id

def run_inference(messages):
    chat = []
    for i, message in enumerate(messages):
      if i % 2 ==0:
          chat.append({"role": "Human", "content": f"{message}"})
      else:
          chat.append({"role": "Assistant", "content": f"{message}"})


    prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)

    inputs = tokenizer(prompt, return_tensors="pt")
    input_ids = inputs["input_ids"].cuda()

    generation_output = model.generate(
            input_ids=input_ids,

            output_scores=True,
            max_new_tokens=128
    )

    for seq in generation_output.sequences:
        output = tokenizer.decode(seq)
        print(output.split("### Assistant: ")[1].strip())
