Another way to program a machine

When programming a machine to achieve a specific goal, we need to communicate our intent to it. Typically, this involves designing a detailed procedure and writing precise instructions in a programming language like Python.

However, some tasks are challenging to describe with step-by-step procedures because we often perform them intuitively without fully understanding the process. For example:

• Determining the sentiment of a given sentence.
• Identifying dishes mentioned in a food review.

omh introduces an alternative way to express our intentions to machines. Instead of relying on imperative procedures, it uses human language instructions and examples. Under the hood, it leverages language models and few-shot learning techniques to interpret and execute these instructions.

Getting Started

pip install omh

Hello World

from openai import OpenAI

openai_client = OpenAI(api_key='**********************')

from omh import def_fn


@def_fn.openai(client=openai_client, opts=my_gpt_opts)
@def_fn.with_instruction('Print Hello World')
@def_fn.with_example(output="Hello World")
@def_fn.with_default_args('Print Hello World')
def hello_world():
    # any code you wrote here will be ignored.
    pass


out = hello_world()
print(out.value)
# hello world

Quick Tutorial

Define a function

Use decorators from from omh import def_fn to define a few-shot learning based function, currently any function definition should include at least the following decorators in their decorators chains:

• an implementation selector such as def_fn.openai() should be always on the top of the decorators chains, and you can provide custom inference parameters, for example: def_fn.openai(opts=GptApiOptions(temperature=1.0))
  the OpenAI client object and any custom.
• use def_fn.with_instruction(instruction: str) to provide instructions.
• use def_fn.with_example(input, output) to provide examples.

def_fn.openai

from omh import def_fn
from omh.impl.openai import GptApiOptions
from openai import OpenAI

openai_client = OpenAI(api_key='**********************')

my_gpt_opts = GptApiOptions(temperature=0)


@def_fn.openai(client=openai_client, opts=my_gpt_opts)
@def_fn.with_instruction('Print Hello World')
@def_fn.with_example(output="Hello World")
@def_fn.with_default_args('Print Hello World')
def hello_world():
    pass


out = hello_world()
out

# Output: Hello World

@def_fn.with_instruction("Given a username, say welcome to the user.")
@def_fn.with_example(input='John', output="Welcome, John!")
@def_fn.with_default_args('New User')

def_fn.with_default_args

from omh import def_fn
from omh.impl.openai import GptApiOptions
from openai import OpenAI

openai_client = OpenAI(api_key='**********************')

my_gpt_opts = GptApiOptions(temperature=0)


@def_fn.openai(client=openai_client, opts=my_gpt_opts)
@def_fn.with_instruction("Given a username, say welcome to the user.")
@def_fn.with_example(input='John', output="Welcome, John!")
@def_fn.with_default_args('New User')
def greet_new_user():
    # any code you wrote here will be ignored.
    pass


out = greet_new_user()
print(out.value)
# Welcome, New User!

out = greet_new_user('Bob')
print(out.value)
# Welcome, Bob!

def_fn.require_args

You can use require_args to set the required keyword arguments for your function, and the function will throw exception when any of those values missing from kwargs.

from omh import def_fn
from omh.impl.openai import GptApiOptions
from openai import OpenAI

openai_client = OpenAI(api_key='**********************')

my_gpt_opts = GptApiOptions(temperature=0)


@def_fn.openai(client=openai_client, opts=my_gpt_opts)
@def_fn.with_instruction("Given a username, say welcome to the user.")
@def_fn.with_example(input={'username': 'John'}, output="Welcome, John!")
@def_fn.require_args('username')
def greet_new_user():
    # any code you wrote here will be ignored.
    pass


out = greet_new_user(username='Bob')
print(out.value)
# Welcome, Bob!

greet_new_user(user='Alice')
# This line will throw error as keyword argument `username` is required

Using the output

out = greet_new_user(username='Bob')
print(out.value)

Batch Mode

Most language model backend nowadays offer batch mode with significant saving in cost if you can afford a delayed response,

You can call omh function in batch mode to take advantage of this, as omh functions' batch mode` offers an easy interface to submit batch job, check status, and, fetching remote response.

from omh import def_fn
from omh.impl.openai import GptApiOptions
from openai import OpenAI

openai_client = OpenAI(api_key='**********************')

my_gpt_opts = GptApiOptions(temperature=0)


@def_fn.openai(client=openai_client, opts=my_gpt_opts)
@def_fn.with_instruction(
    "Extract all wikipedia entities mentioned in the text and format them in JSON as following [{name: '', url: ''}].")
@def_fn.with_example(
    input="An analog computer or analogue computer is a type of computer that uses the continuous variation"
          "aspect of physical phenomena such as electrical, mechanical, or hydraulic quantities (analog signals) "
          "to model the problem being solved.",
    output=[
        {
            "name": "computer",
