Amazon SageMaker AI serverless model customization has expanded to support full fine-tuning across over 25 open-source models, including GPT-OSS, Gemma, Llama, Nemotron, and Qwen families. This update allows practitioners to update all model parameters rather than relying solely on parameter-efficient methods like LoRA. The capability enables deeper adaptation for complex tasks requiring specialized reasoning, strict output formatting, or internalization of large proprietary datasets.

• Full fine-tuning is now available in SageMaker AI serverless, moving beyond just LoRA and other PEFT methods.
• Support covers 25+ open-source models from major families like Llama, Gemma, Qwen, Nemotron, and GPT-OSS.
• Enables deep domain adaptation for complex reasoning patterns and specialized output structures.
• Ideal for internalizing knowledge from large proprietary datasets where surface-level adjustments are insufficient.

Amazon EMR on EC2 now supports interactive Apache Spark sessions via Spark Connect, enabling developers to run persistent Spark contexts from local IDEs like Jupyter and VS Code. This client-server architecture decouples the application client from the Spark driver, allowing seamless blending of local Python code with remote Spark operations. Users can manage and debug these sessions directly through the EMR console or within Amazon SageMaker Unified Studio notebooks.

• Decouples local IDEs from Spark drivers via Spark Connect client-server architecture
• Enables persistent interactive sessions spanning multiple cells and scripts
• Supports debugging active and completed sessions in the EMR console
• Integrates with Amazon SageMaker Unified Studio for managed notebook workflows
• Allows data engineers to use preferred local tooling while running remote Spark tasks
