Rig 0.14.0 - 📡 Streams upgrade, new OpenAI responses API and more

[mateobelanger]

Rig 0.14.0 is out now!

This release brings major upgrades to the developer experience and wider GenAI provider support — with a strong focus on flexibility, integration, and streaming control.

⚠️ Breaking changes

• Migrated all crates to Rust 2024 edition
• Refactored internals to support stream cancellation and trait-based document ingestion

Please see the bottom of this post for potential migration paths.

🔥 New features

• Add InsertDocuments trait for unified document ingestion
• Support for stream cancellation via AbortHandle
• Support for loading PDFs/files directly as Vec
• Add max_tokens method to ExtractorBuilder
• Turn Extractor into its equivalent Agent type
• Environment variable support for OLLAMA_API_BASE_URL (for ollama integration)
• Add support for Voyage AI
• Add support for OpenAI's new responses API (and make it the default for .completion_model())
• Add multi-turn streaming example
• Support custom client configurations via with_custom_client

📚 Other improvements

• Improved documentation for multi-turn streaming
• Declared shared dependencies in workspace for cleaner builds
• Dependency updates + clippy fixes across all targets
• Minor error clarity improvements
• A myriad of bug fixes

Migration path

• If you are currently using the OpenAI Completions API and still need to specifically use it, there is an escape hatch: the new ResponsesCompletionModel has a function called completions_api() that will take you straight to where you need to. If you need an agent builder out of that, there is now additionally an into_agent_builder() on the completions API CompletionModel.
• The insert_documents functions on various vector stores are now granted by InsertDocuments. Please note not all integrations use this yet (as some integrations never had an insert_documents function) and we're working on this!
