Nova Forge is now generally available on AWS, enabling developers to build custom frontier models using Amazon Nova. The service supports model development across pre-training, mid-training, and post-training phases on SageMaker AI. Key features include blending proprietary data with Nova-curated datasets, Reinforcement Fine Tuning with custom reward functions, built-in responsible AI toolkit for safety guardrails, and early access to Nova 2 Pro and Nova 2 Omni models. The service aims to help organizations create models that understand their proprietary knowledge while maintaining general capabilities and minimizing catastrophic forgetting.
