What is Amazon Nova Forge?
Amazon Nova Forge is designed for companies that want to build frontier-level AI models without the heavy operational or research overhead typically required. It provides access to Nova’s progressive model checkpoints, letting teams inject their proprietary data at the exact stages where models learn most efficiently. This enables customers to expand model capability while protecting foundational skills through blended training with Nova-curated datasets. With support for continued pre-training, supervised fine-tuning, and robust reinforcement learning, Nova Forge covers the full spectrum of modern AI development. The platform also introduces a responsible AI toolkit with configurable guardrails, helping enterprises maintain safety, alignment, and compliance across deployments. Leading organizations—from Reddit to Nimbus Therapeutics—report major breakthroughs, such as replacing multiple ML pipelines with a single unified system or achieving superior results in complex scientific prediction tasks. Nova Forge’s architecture is built to run securely on AWS, leveraging the scalability of SageMaker AI for distributed training, model hosting, and lifecycle management. Its API-driven workflow lets companies use their internal tools and real-world environments to optimize models through reinforcement learning. As customers gain early access to new Nova models, they can continually refine their own specialized versions in sync with the latest advancements. Ultimately, Nova Forge transforms AI development into a controllable, efficient, and cost-effective process for teams that need frontier-grade intelligence customized to their business.

Really good to build frontier models
Date: Dec 03 2025SummaryAmazon Nova Forge is one of the most accessible and cost-effective ways to build custom frontier models tailored to your business. From continued pre-training to supervised and reinforcement fine-tuning, it offers end-to-end control of the entire model-development lifecycle—all backed by AWS security and scalability. Whether you’re optimizing content moderation, accelerating drug discovery, enhancing financial analysis, or pushing the boundaries of agentic AI, Nova Forge provides the tools and infrastructure needed to achieve state-of-the-art performance. For organizations serious about creating differentiated, domain-specific AI models, Nova Forge is an outstanding and future-proof choice.
PositiveAmazon Nova Forge is a game-changing platform for organizations that want to build their own frontier-level AI models without reinventing the entire training pipeline. It offers unmatched flexibility—letting teams start from early Nova checkpoints, blend proprietary datasets with Amazon’s curated training data, and fine-tune models through supervised training and reinforcement learning. The ability to plug into your own environment for RL, combined with built-in responsible AI guardrails, makes Nova Forge incredibly powerful for domain-specific, safety-aligned model development. Real-world use cases from Reddit, Nimbus Therapeutics, NRI, Cosine AI, Sony, and Siemens demonstrate remarkable gains in accuracy, efficiency, and cost savings.
NegativeBecause Nova Forge is designed for sophisticated model builders, it requires a certain level of ML expertise and organizational readiness. Teams without robust datasets or clear training objectives may not fully benefit from its advanced customization workflow. In addition, while SageMaker AI provides managed infrastructure, large-scale training efforts can still involve sizable compute investments, making the platform best suited for enterprises and research groups with meaningful AI budgets.
