Prerequisites

​
Important notes

  • Together.ai usage may incur costs based on your Together.ai plan.
  • Be mindful of sensitive data and consider security measures when integrating with external services.
First you’ll need to install required libraries and enter your Together API key. 
%pip install -qU pixeltable together

import os
import getpass

if 'TOGETHER_API_KEY' not in os.environ:
    os.environ['TOGETHER_API_KEY'] = getpass.getpass('Together API Key: ')
Now let’s create a Pixeltable directory to hold the tables for our demo. 
import pixeltable as pxt

# Remove the 'together_demo' directory and its contents, if it exists
pxt.drop_dir('together_demo', force=True)
pxt.create_dir('together_demo')

​
Chat completions

Create a Table: In Pixeltable, create a table with columns to represent your input data and the columns where you want to store the results from OpenAI. 
from pixeltable.functions import together

chat_t = pxt.create_table('together_demo.chat', {'input': pxt.String})

messages = [{'role': 'user', 'content': chat_t.input}]

chat_t.add_computed_column(output=together.chat_completions(
    messages=messages,
    model='meta-llama/Llama-3.3-70B-Instruct-Turbo',
    model_kwargs={
        # Optional dict with parameters for the Together API
        'max_tokens': 300,
        'stop': ['\n'],
        'temperature': 0.7,
        'top_p': 0.9,
    }
))
chat_t.add_computed_column(response=chat_t.output.choices[0].message.content)

# Start a conversation
chat_t.insert([
    {'input': 'How many species of felids have been classified?'},
    {'input': 'Can you make me a coffee?'}
])
chat_t.select(chat_t.input, chat_t.response).head()

​
Embeddings

emb_t = pxt.create_table('together_demo.embeddings', {'input': pxt.String})
emb_t.add_computed_column(embedding=together.embeddings(
    input=emb_t.input,
    model='BAAI/bge-base-en-v1.5'
))

emb_t.insert([{'input': 'Together AI provides a variety of embeddings models.'}])

emb_t.head()

​
Image generations

image_t = pxt.create_table('together_demo.images', {'input': pxt.String})
image_t.add_computed_column(img=together.image_generations(
    image_t.input,
    model='black-forest-labs/FLUX.1-schnell',
    model_kwargs={'steps': 5}
))

image_t.insert([
    {'input': 'A friendly dinosaur playing tennis in a cornfield'}
])

image_t

image_t.head()
