This instruction model was built via parameter-efficient QLoRA finetuning of llama-2-70b on the first 25k rows of ehartford/dolphin (an open-source implementation of Microsoft's Orca). Finetuning was executed on a single H100 (80 GB PCIe) for roughly 17 hours on the Lambda Labs platform.

Note: This model was ranked 6th on πŸ€—'s Open LLM Leaderboard in Aug 2023

Example 3:


You are a helpful assistant. Tell me a recipe for vegan banana bread.\n


Sure! Here's a delicious and easy vegan banana bread recipe:


  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1/2 cup vegan butter (such as Earth Balance)
  • 1/2 cup vegan milk (such as almond milk)
  • 1/2 cup unsweetened applesauce
  • 1/2 cup mashed ripe bananas (about 2 medium bananas)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon ground cloves
  • 1/2 cup chopped walnuts (optional)


  1. Preheat the oven to 350Β°F (175Β°C). Grease a 9x5-inch loaf pan with vegan butter or cooking spray.
  2. In a large bowl, mix together the flour, sugar, vegan butter, vegan milk, applesauce, bananas, baking soda, salt, cinnamon, nutmeg, and cloves. Stir until well combined.
  3. Fold in the chopped walnuts, if using.
  4. Pour the batter into the prepared loaf pan.
  5. Bake for 50-60 minutes, or until a toothpick inserted into the center of the bread comes out clean.
  6. Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
  7. Slice and enjoy!

Note: You can also add chocolate chips, dried fruit, or other mix-ins to the batter for extra flavor and texture. Enjoy your vegan banana bread!

Model description

The architecture is a modification of a standard decoder-only transformer and was trained as a causal language model (clm).

The llama-2-70b models have been modified from a standard transformer in the following ways:

Hyperparameter Value
n_parameters 70B
tokens 2.0T
vocab size 32000
sequence length 4096
grouped-query attention βœ”οΈ

Pre-training data

For more details on the pretraining process, see Llama-2-70b-hf.

The data was tokenized using the Llama-2-70b-hf tokenizer.

Limitations and biases

The following language is modified from EleutherAI's GPT-NeoX-20B

This model can produce factually incorrect output, and should not be relied on to produce factually accurate information. This model was trained on various public datasets. While great efforts have been taken to clean the pretraining data, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Basic usage

from peft import PeftModel, PeftConfig
from transformers import (

format_template = "You are a helpful assistant. {query}\n"
# First, format the prompt
query = "Tell me a recipe for vegan banana bread."
prompt = format_template.format(query=query)

# Inference can be done using model.generate
print("\n\n*** Generate:")

input_ids = tokenizer(prompt, return_tensors="pt").input_ids.cuda()
with torch.autocast("cuda", dtype=torch.bfloat16):
    output = model.generate(
