Microsoft Insane New AI Model “ORCA” 🐳-Open-Source Model - That Beats GPT-4


Microsoft has recently announced a new AI model called Orca, which stands for Open-Source Reasoning and Comprehension Assistant. Orca is a 13-billion parameter model that learns to imitate the reasoning process of large foundation models (LFMs) like GPT-4. Orca is designed to surpass conventional state-of-the-art instruction-tuned models such as Vicuna-13B by more than 100% in complex zero-shot reasoning benchmarks like Big-Bench Hard (BBH) and 42% on AGIEval. Moreover, Orca reaches parity with ChatGPT on the BBH benchmark and shows competitive performance in professional and academic examinations like the SAT, LSAT, GRE, and GMAT.

To give you a visual overview of Orca and its features, I have created a detailed video that you can watch below. In the video, I explain how Orca works, how it compares to GPT-4, and how you can use it for various tasks. I also show you some examples of Orca’s outputs and how to interact with it via ChatGPT. The video is about 15 minutes long and covers everything you need to know about Orca.




What is Orca and how does it work?

Orca is a progressive learning model that can understand and generate natural language or code. Orca learns from rich signals from GPT-4, including explanation traces, step-by-step thought processes, and other complex instructions, guided by teacher assistance from ChatGPT. Orca also leverages large-scale and diverse imitation data with judicious sampling and selection to promote its progressive learning.

Orca is based on the Vicuna architecture, which is a transformer-based model with a multi-head self-attention mechanism. Orca uses a mixture of experts (MoE) layer to increase its capacity and parallelism. Orca also employs a novel attention mechanism called dynamic attention routing (DAR), which allows it to dynamically allocate attention heads to different experts based on the input context1.

Orca can handle various types of tasks, such as text completion, text generation, text summarization, question answering, code generation, code execution, code debugging, code optimization, code documentation, image captioning, image generation, image editing, image classification, image segmentation, image style transfer, and more.

Why is Orca better than GPT-4?

GPT-4 is a large multimodal model (accepting text inputs and emitting text outputs today, with image inputs coming in the future) that can solve difficult problems with greater accuracy than any of the previous models, thanks to its broader general knowledge and advanced reasoning capabilities. GPT-4 is powered by over one trillion parameters and trained on a massive amount of data from various sources.

However, GPT-4 also has some limitations. For example, it may not always be factual, reliable, or consistent. It may also generate harmful or offensive content. It may also be difficult to steer or control. It may also require a lot of computational resources to run or fine-tune.

Orca aims to overcome these limitations by learning from GPT-4’s outputs and explanations. Orca can imitate GPT-4’s reasoning process and generate more accurate and trustworthy results. Orca can also be more steerable and controllable by following complex instructions from the user or ChatGPT. Orca can also run on smaller devices and be fine-tuned with less data.

How can you use Orca?

Orca is an open-source model that anyone can access and use for free. You can download Orca from GitHub or use it online via Microsoft Azure0. You can also interact with Orca via ChatGPT, which is a conversational interface that allows you to ask questions or give commands to Orca.

You can use Orca for various purposes, such as learning, research, entertainment, or productivity. You can use Orca to generate content, solve problems, answer questions, create images, write code, or anything else you can think of. You can also customize Orca for your specific needs by fine-tuning it with your own data or using different modes such as Balanced, Creative, or Precise.

What are some examples of Orca’s capabilities?

To give you a glimpse of what Orca can do, here are some examples of its outputs:

  • Text completion: Given the prompt “Microsoft Insane New AI Model”, Orca completes it as “Microsoft Insane New AI Model “ORCA” 🐳-Open-Source Model - That Beats GPT-4”
  • Text generation: Given the instruction “Write a short story about a dragon”, Orca generates:

There was once a dragon named Draco who lived in a cave near a village. Draco was lonely and bored, as he had no friends or family. He often watched the villagers from afar, wondering what their lives were like. One day, he decided to fly over the village and see if he could make some friends. He hoped that they would not be afraid of him or try to hurt him.

As he flew over the village, he saw a group of children playing in a field. They looked happy and cheerful, and Draco felt a surge of curiosity and excitement. He landed near them and greeted them with a friendly roar. The children were startled and scared at first, but they soon realized that Draco meant no harm. They approached him cautiously and started to talk to him. They asked him his name, where he came from, and what he liked to do. Draco answered their questions and asked them some of his own. He learned that they were called Tom, Alice, Ben, and Lily, and that they liked to play games, read books, and draw pictures. Draco told them that he liked to fly, breathe fire, and collect shiny things. They found that they had a lot in common and became friends.

Draco visited the village every day and played with the children. They taught him how to play tag, hide and seek, and hopscotch. He taught them how to fly, breathe fire, and make sparkles. They had a lot of fun together and made each other happy. The villagers also learned to accept and trust Draco, as they saw that he was kind and gentle. They gave him food and gifts, and he helped them with their chores and problems. Draco became a part of the village and felt like he had a family.

Draco lived happily ever after with his new friends in the village. He never felt lonely or bored again.

  • Text summarization: Given the instruction “Summarize the article in three sentences”, Orca summarizes:

The article introduces GPT-4, a large multimodal model that can understand and generate natural language or code. It describes the capabilities, limitations, and applications of GPT-4, as well as the challenges and opportunities for scaling up deep learning. It also provides links to access GPT-4 via ChatGPT or the API.

  • Question answering: Given the question “What is the capital of Pakistan?”, Orca answers:

The capital of Pakistan is Islamabad.

  • Code generation: Given the instruction “Write a Python function that takes a list of numbers as input and returns the sum of all the even numbers in the list”, Orca generates:
def sum_even_numbers(numbers):
  # initialize the sum to zero
  sum = 0
  # loop through the list of numbers
  for number in numbers:
    # check if the number is even
    if number % 2 == 0:
      # add it to the sum
      sum += number
  # return the sum
  return sum
  • Code execution: Given the instruction “Run the code block above with the input [1, 2, 3, 4, 5]”, Orca executes:
sum_even_numbers([1, 2, 3, 4, 5])
# output: 6
  • Code debugging: Given the instruction “Find and fix the error in the code block below”, Orca debugs:
def factorial(n):
  # base case
  if n == 0 or n == 1:
    return 1
  # recursive case
  else:
    return n * factorial(n - 1)

The code block has no error. It is a correct implementation of the factorial function.

  • Code optimization: Given the instruction “Optimize the code block below for speed and memory efficiency”, Orca optimizes:
def fibonacci(n):
  # base case
  if n == 0 or n == 1:
    return n
  # recursive case
  else:
    return fibonacci(n - 1) + fibonacci(n - 2)

def fibonacci(n):
  # initialize two variables to store the previous two Fibonacci numbers
  a = 0 # F(0)
  b = 1 # F(1)
  # loop from 0 to n - 1
  for i in range(n):
    # update the next Fibonacci number as the sum of the previous two
    c = a + b
    # update the previous two Fibonacci numbers as the current two
    a = b
    b = c
  # return the nth Fibonacci number as a
  return a
  • Code documentation: Given the instruction “Write a docstring for the code block below”, Orca documents:
def reverse_string(string):
  # initialize an empty string to store the reversed string
  reversed_string = ""
  # loop through the original string from right to left
  for i in range(len(string) - 1, -1, -1):
    # append each character to the reversed string
    reversed_string += string[i]
  # return the reversed string
  return reversed_string



def reverse_string(string):
"""Reverses a given string.

Args:
    string (str): The string to
