Amazon SageMaker AI Now Lets You Fine-Tune 25+ Open-Source Models Without Managing Infrastructure
Amazon SageMaker AI serverless model customization just got a serious upgrade—full fine-tuning is now available for 25+ open-source models including Llama, Gemma, and Qwen. Unlike parameter-efficient methods like LoRA, you can now tweak all model weights for deeper domain-specific learning, perfect when you need your AI to master specialized reasoning or complex output formats. The best part? SageMaker handles all the infrastructure headaches, so you just pay for what you use. Available in US East, US West, Asia Pacific, and Europe regions.
