OpenAI Python SDK v2.27.0 adds Sora video API improvements and character support
OpenAI released version 2.27.0 of its Python SDK on March 13, 2026, adding significant improvements to the Sora video generation API. The update introduces character API support, video extension and editing capabilities, and higher resolution export options.
OpenAI has released v2.27.0 of its Python SDK, the latest update to the official library for integrating OpenAI APIs into Python applications.
Key Changes
The release centers on expanding Sora video generation capabilities. The primary feature addition is Sora API improvements, which include:
- Character API: Introduces character-based controls for video generation
- Video extensions and edits: Enables developers to extend existing videos and apply targeted edits
- Higher resolution exports: Supports video output at elevated resolutions
These features appear designed to give developers more granular control over video generation workflows, moving beyond simple prompt-to-video creation toward more iterative and controlled editing capabilities.
Technical Updates
Beyond the Sora enhancements, v2.27.0 includes:
- API schema updates: General API definition updates reflected across the SDK
- Bug fixes: Repair of the merged videos resource, addressing a previously broken endpoint
- Infrastructure improvements: WebSocket protocol alignment and proper capitalization standardization
- Codegen updates: Internal tooling changes for SDK code generation
The bug fix for the merged videos resource suggests this functionality had issues in v2.26.0 that are now resolved.
What This Means
The Sora API improvements indicate OpenAI is prioritizing video generation as a development platform, not just an internal capability. The addition of character controls and editing features suggests the company is moving toward production-ready video generation workflows that support professional use cases requiring iterative refinement rather than one-shot generation.
Developers using the Python SDK should update to access these new Sora capabilities. The merged videos resource fix is a necessary update for anyone relying on that functionality.
For context, the OpenAI Python SDK serves as the primary interface for developers building applications with OpenAI's APIs, making each release significant for the developer ecosystem. This version demonstrates continued investment in expanding Sora's feature set beyond basic video generation.
