Amazon Bedrock Adds Reinforcement Fine‑Tuning for Models

🔧 Amazon Bedrock now supports reinforcement fine-tuning, enabling developers to improve model accuracy without deep ML expertise or large labeled datasets. The service automates the reinforcement fine-tuning workflow and trains models by learning from feedback on multiple candidate responses, improving model judgment about what makes a good reply. AWS reports an average 66% accuracy gain over base models, allowing teams to deploy smaller, faster, and more cost-effective variants while maintaining quality. At launch the feature supports Amazon Nova 2 Lite, and it can be accessed via the Bedrock console or APIs.

Amazon Nova Forge: Build Frontier Models with Nova

🚀 Amazon Web Services announced general availability of Nova Forge, a SageMaker AI service that enables organizations to build custom frontier models from Nova checkpoints across pre-, mid-, and post-training phases. Developers can blend proprietary data with Amazon-curated datasets, run Reinforcement Fine Tuning (RFT) with in-environment reward functions, and apply custom safety guardrails via a built-in responsible AI toolkit. Nova Forge includes early access to Nova 2 Pro and Nova 2 Omni and is available today in US East (N. Virginia).

Amazon Nova 2 Omni: Multimodal Reasoning Model Preview

🚀 Amazon announced Nova 2 Omni, an all‑in‑one multimodal model in preview that accepts text, images, video, and speech inputs while producing text and image outputs. It offers a 1M token context window, supports 200+ languages for text and 10 for speech, and provides image generation/editing and multi‑speaker speech transcription with native reasoning. Early access is available to Nova Forge and authorized customers.

Amazon Web Grounding for Nova Models Now Generally Available

🌐 Web Grounding is now generally available as a built-in tool for Nova models, usable today with Nova Premier via the Amazon Bedrock tool use API. It retrieves and incorporates publicly available information with citations to support responses, enabling a turnkey RAG solution that reduces hallucinations and improves accuracy. Cross-region inference makes the tool available in US East (N. Virginia), US East (Ohio), and US West (Oregon). Support for additional Nova models will follow.

Amazon Nova adds customizable content moderation settings

🔒 Amazon announced that Amazon Nova models now support customizable content moderation settings for approved business use cases that require processing or generating sensitive content. Organizations can adjust controls across four domains—safety, sensitive content, fairness, and security—while Amazon enforces essential, non-configurable safeguards to protect children and preserve privacy. Customization is available for Amazon Nova Lite and Amazon Nova Pro in the US East (N. Virginia) region; customers should contact their AWS Account Manager to confirm eligibility.

Simplified Amazon Bedrock Model Access and Governance Controls

🔐 Amazon Bedrock now automatically enables serverless foundation models in each AWS Region, removing the prior per-model enablement step and retiring the Model Access page and PutFoundationModelEntitlement IAM permission. Access is managed through standard AWS controls—IAM and Service Control Policies (SCPs)—so account- and organization-level governance remains intact. Existing model restrictions enforced by IAM or SCPs continue to apply, and previously enabled models are unaffected. Administrators should transition to scoped IAM/SCP policies and patterns such as wildcards and NotResource denies to maintain least-privilege control.
