Genkit Python SDK v0.5.2

GenKit 0.5.2 release notes

The big structural change in this release is a full pass on package layout, public API surface, and types (#4879), plus a simpler Dev UI integration path (#4812).

On the fixes side: we closed a batch of issues from a bug bash (#4987); FastAPI and Flask handlers should return errors in a shape clients can actually parse (#4954); reflection and streaming handle primitive values correctly now (#4958); Dev UI’s action list is cached and the Google GenAI plugin uses the right default embedding model for embeddings (#4956).

Multipart tool responses can carry an optional metadata field now (#4865).

Breaking changes

If you upgrade from 0.5.1, the main thing to watch is #4879: several imports and types moved. Expect missing modules and renamed symbols until you align with the new layout.

Migrating

Install the new version:

pip install -U "genkit==0.5.2"

Bump the same version in pyproject.toml or requirements.txt if you pin it.

Then chase import errors. The supported modules to import from are genkit, genkit.model, genkit.embedder, and genkit.evaluator. Implementation code lives under genkit._ai and genkit._core; treat those as internal unless you know you need them.

Rough mapping: use from genkit import … for the main API (see __all__ in genkit/__init__.py). Use genkit.model for model types (that replaces the old genkit.model_types and most of what people pulled from genkit.types). Use genkit.embedder and genkit.evaluator for those protocols. Plugin work may still go through genkit.plugin_api where we document it.

Packages that no longer exist:

• genkit.types → split across genkit, genkit.model, genkit.embedder (check each __init__.py for the symbol).
• genkit.model_types → genkit.model
• genkit.ai → from genkit import Genkit and the rest of the public genkit exports
• genkit.blocks, genkit.core, genkit.aio → use genkit and genkit.model in app code; don’t wire apps to genkit._ai. Only reach into genkit._core.* if you’re doing something advanced—the old internals are under genkit._core and genkit._ai now.

Tips

1. Do the upgrade in a branch. After bumping the dependency, run your test suite once—let it fail—and also run your type checker (mypy, pyright, or whatever you use) over the same tree. Fix imports before you chase logic bugs; most failures will be ModuleNotFoundError or missing attributes until imports line up.

2. When you’re not sure where a type moved, open the installed package (or this repo’s py/packages/genkit/src/genkit/) and skim genkit/__init__.py, genkit/model/__init__.py, and genkit/embedder/__init__.py.
