Pixeltable’s Anthropic integration enables you to access Anthropic’s Claude LLM via the Anthropic API.

​
Prerequisites

​
Important Notes

  • Anthropic usage may incur costs based on your Anthropic 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 an Anthropic API key. 
%pip install -qU pixeltable anthropic

import os
import getpass

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

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

Connected to Pixeltable database at: postgresql+psycopg://postgres:@/pixeltable?host=/Users/asiegel/.pixeltable/pgdata
Created directory `anthropic_demo`.

<pixeltable.catalog.dir.Dir at 0x33944b3a0>

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 Anthropic. 
from pixeltable.functions import anthropic

# Create a table in Pixeltable and add a computed column that calls Anthropic

t = pxt.create_table('anthropic_demo.chat', {'input': pxt.String})

msgs = [{'role': 'user', 'content': t.input}]
t.add_computed_column(output=anthropic.messages(
    messages=msgs,
    model='claude-3-haiku-20240307',
    max_tokens=300,
    model_kwargs={
        # Optional dict with parameters for the Anthropic API
        'system': 'Respond to the prompt with detailed historical information.',
        'top_k': 40,
        'top_p': 0.9,
        'temperature': 0.7
    }
))

Created table `chat`.
Added 0 column values with 0 errors.

# Parse the response into a new column
t.add_computed_column(response=t.output.content[0].text)

Added 0 column values with 0 errors.

# Start a conversation
t.insert([{'input': 'What was the outcome of the 1904 US Presidential election?'}])
t.select(t.input, t.response).show()

Computing cells: 100%|████████████████████████████████████████████| 3/3 [00:01<00:00,  1.54 cells/s]

input response
What was the outcome of the 1904 US Presidential election? The outcome of the 1904 US presidential election was: - The Republican candidate, Theodore Roosevelt, won the election. Roosevelt had become president in 1901 after the assassination of President William McKinley, and this was his first election as the Republican nominee. - Roosevelt defeated the Democratic candidate, Alton B. Parker, by a wide margin, winning 56.4% of the popular vote and 336 electoral votes compared to Parker's 37.6% of the popular vote and 140 electoral votes. - Roosev ...... cies and his aggressive foreign policy, known as "Big Stick" diplomacy. - The election was also notable for the fact that it was the first time a sitting president (Roosevelt) was elected in his own right after originally assuming the presidency due to the death of his predecessor. So in summary, Theodore Roosevelt won a decisive victory over Alton B. Parker, cementing his status as a powerful and popular president during the Progressive Era of American politics in the early 20th century.
