Modal 1.0 Released: More Stable Python SDK with Explicit Configuration

Modal has launched version 1.0 of its Python SDK client, a milestone the company says brings a new level of maturity and stability to its serverless cloud compute platform, with far fewer breaking changes expected going forward. The release removes "magic" behaviors such as automatic mounting of local packages, splits core functionality across separate decorators like the new @modal.concurrent, and consolidates local file handling under the modal.Image class. Modal also plans SDKs for other languages and is exploring how the platform should serve AI-driven agent workflows.
