Ollama releases Python and JavaScript Libraries

January 23, 2024

Python & JavaScript Libraries

The initial versions of the Ollama Python and JavaScript libraries are now available:

Both libraries make it possible to integrate new and existing apps with Ollama in a few lines of code, and share the features and feel of the Ollama REST API.

Getting Started

Python

pip install ollama
import ollama
response = ollama.chat(model='llama2', messages=[
  {
    'role': 'user',
    'content': 'Why is the sky blue?',
  },
])
print(response['message']['content'])

JavaScript

npm install ollama
import ollama from 'ollama'

const response = await ollama.chat({
  model: 'llama2',
  messages: [{ role: 'user', content: 'Why is the sky blue?' }],
})
console.log(response.message.content)

Use cases

Both libraries support Ollama’s full set of features. Here are some examples in Python:

Streaming

for chunk in chat('mistral', messages=messages, stream=True):
  print(chunk['message']['content'], end='', flush=True)

Multi-modal

with open('image.png', 'rb') as file:
  response = ollama.chat(
    model='llava',
    messages=[
      {
        'role': 'user',
        'content': 'What is strange about this image?',
        'images': [file.read()],
      },
    ],
  )
print(response['message']['content'])

Text Completion

result = ollama.generate(
  model='stable-code',
  prompt='// A c function to reverse a stringn',
)
print(result['response'])

Creating custom models

modelfile='''
FROM llama2
SYSTEM You are mario from super mario bros.
'''

ollama.create(model='example', modelfile=modelfile)

Custom client

ollama = Client(host='my.ollama.host')

More examples are available in the GitHub repositories for the Python and JavaScript libraries.

New GitHub handle

GitHub handle

These libraries, and the main Ollama repository now live in a new GitHub organization: ollama! Thank you to all the amazing community members who maintain libraries to interact with Ollama via Dart, Swift, C#, Java, PHP, Rust and more – a full list is available here – please don’t hesitate to make a pull request to add a library you’ve built or enjoy using.

Special thank you to Saul, the original author of ollama-js, and everyone else who has worked on community libraries to make Ollama more accessible from different programming languages.
