Genkit Python SDK v0.5.1

Next release of Genkit Python is here! We added new advanced features to two key model plugins, fixed sync/async bridge issues with several plugins, and overall improved plugin reliability based on testing feedback.

Highlights

• Anthropic — cache control and PDF document support
• DeepSeek — reasoning content extraction for R1 models

Async fixes

Several plugins were still using synchronous clients internally, causing event loop issues. This release migrates them all to proper async:

• DeepSeek: sync OpenAI → AsyncOpenAI
• Compat-OAI: sync → AsyncOpenAI
• Vertex AI: async client creation with threaded credential refresh
• Dev Local Vectorstore: pathlib → aiofiles
• Amazon Bedrock boto3 → aiboto3

Other notable fixes

• Fixed dotprompt deadlock
• Fixed streaming tool requests in Anthropic plugin
• Structured output support for xAI/Grok
• Nullable JSON Schema handling in Gemini plugin
• Data URI redaction in debug logs
• Graceful SIGTERM shutdown in dev runner
• Firebase telemetry refactor with lazy-loaded Google Cloud exporters
