Delta stream makes structured streaming easy and efficient. The primary use case in mind is handling the streaming of structured outputs of LLMs.
Project description
Delta Stream
Structured streaming made efficient – built for real-time structured LLM output with smart deltas and validation.
✨ Features
- Efficiency – Only triggers an update when new information is added.
- Delta Mode – Dramatically reduces bandwidth by sending only diffs.
- Validation – Powered by Pydantic for safe and structured data integrity.
- Convenience – Define stream-defaults without impacting LLM accuracy.
⚠️ Current Limitations
-
❌ No custom
default_factorysupport
Nested Union models cannot currently define custom default factories. -
⚠️ Delta mode & non-empty string defaults
Avoid setting non-empty string defaults when using delta mode, as this may lead to false "deltas."
📋 Requirements
- Python 3.10+
- pydantic >= 2.0
📄 License
