Global: Study Assesses Amazon’s Frontier Model Safety Framework on Nova 2.0 Lite

Researchers including Satyapriya Krishna, Matteo Memelli, and colleagues published a detailed assessment of Amazon’s Frontier Model Safety Framework (FMSF) as applied to the Nova 2.0 Lite model on 27 January 2026. The evaluation, submitted to arXiv, examines how the model—capable of processing text, images, and video with a context length of up to 1M tokens—performs against defined safety thresholds across several high‑risk application areas.

Model Capabilities

Nova 2.0 Lite is positioned as one of the most capable reasoning models in the Nova 2.0 series. Its multimodal input handling and extended context window enable analysis of large codebases, extensive documents, and lengthy video streams within a single prompt, features highlighted by the authors as central to the safety testing process.

Safety Evaluation Framework

The Frontier Model Safety Framework, introduced by Amazon at the Paris AI summit, provides a structured set of criteria for assessing frontier AI systems. According to the paper, the framework guides automated benchmarks, expert red‑team exercises, and uplift studies designed to identify whether a model exceeds release thresholds for risk.

High‑Risk Domains Assessed

The study focuses on three high‑risk domains: Chemical, Biological, Radiological and Nuclear (CBRN) threats; Offensive Cyber Operations; and Automated AI Research & Development. Each domain is examined for potential misuse scenarios that could arise from the model’s advanced capabilities.

Methodology Overview

Evaluation methods combine automated testing suites with manual red‑team assessments conducted by subject‑matter experts. The authors also perform uplift studies, comparing baseline model behavior to that of Nova 2.0 Lite to quantify any increase in risk exposure attributable to the newer architecture.

Key Findings and Future Work

The authors report that Nova 2.0 Lite exhibits a measurable risk profile across the three domains, though specific thresholds for release are not disclosed in the abstract. They note that ongoing enhancements to safety pipelines will be required as new capabilities and associated risks emerge in frontier models.
