description	Generate Cypher queries from natural language using Code-Graph-RAG's CypherGenerator.

Cypher Generator

The CypherGenerator translates natural language questions into Cypher queries for the knowledge graph.

Usage

import asyncio
from cgr import CypherGenerator

async def main():
    gen = CypherGenerator()
    cypher = await gen.generate("Find all classes that inherit from BaseModel")
    print(cypher)

asyncio.run(main())

Configuration

The Cypher generator uses the configured Cypher provider. Set it via environment variables:

CYPHER_PROVIDER=google
CYPHER_MODEL=gemini-3.5-flash-lite
CYPHER_API_KEY=your-google-api-key

Or with Anthropic:

CYPHER_PROVIDER=anthropic
CYPHER_MODEL=claude-haiku-4-5
CYPHER_API_KEY=sk-ant-your-anthropic-key

Or programmatically:

from cgr import settings

settings.set_cypher("google", "gemini-3.5-flash-lite", api_key="your-google-api-key")

Or with Anthropic:

from cgr import settings

settings.set_cypher("anthropic", "claude-haiku-4-5", api_key="sk-ant-your-key")
