Migration Guides

​

Python SDK Migrations

​

Migrating to 0.5.0 (PluginV2)

Version 0.5.0 introduces a breaking change with the PluginV2 refactor. Key Changes:

• Plugins use standardized registration pattern
• More consistent configuration across plugins
• Improved type safety

Migration Steps:

1. Update plugin initialization:
   # Before (0.4.0)
   from genkit.plugins.google_genai import GoogleGenAI
   ai = Genkit(plugins=[GoogleGenAI(api_key=key)])
   
   # After (0.5.0)  
   from genkit.plugins.google_genai import google_genai
   ai = Genkit(plugins=[google_genai(api_key=key)])
   
2. Update async patterns:
   # Version 0.5.0 is fully async-first
   # Remove any sync base class usage
   async def my_flow():
       result = await ai.generate(...)
   
3. Update embed API calls:
   # Before
   embeddings = embedder.embed(texts)
   
   # After (matches JS API)
   embedding = await embedder.embed(text)  # single
   embeddings = await embedder.embed_many(texts)  # multiple
