Usage

Tip

Claude 3.7 Sonnet is recommended for best results.

Here's a simple example of how to use Encite:

export ANTHROPIC_API_KEY=your-api-key

from encite import find_entities
from langchain_anthropic import ChatAnthropic

# Initialize the Claude model
model = ChatAnthropic(model="claude-3-7-sonnet-latest")

# Example text
text = "John Smith works at Apple Inc. in California."

# Extract entities
entities = find_entities(model, text, entity_types=["person", "company"])

# Print results
print(entities)

Expected output:

[
    Entity(entity_type="person", name="John Smith", start_char_index=0, end_char_index=10),
    Entity(entity_type="company", name="Apple Inc", start_char_index=20, end_char_index=29)
]
