It's a genuine coin-flip between Amazon Nova Micro and Sonar Pro: 1 category wins each, with the rest tied. Amazon Nova Micro is roughly 107.1× cheaper on output tokens ($0.14 vs $15.00 per 1M). Sonar Pro accepts 200K tokens vs 128K, 1.6× the room for long documents and codebases.

No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores. Both target the same set of modalities (text), so the deciding factors are price, context, and raw quality. Both are closed-weight, API-only.

Sonar Pro is the newer of the two, released 2 months after Amazon Nova Micro, which usually means a more recent knowledge cutoff and updated safety post-training. Amazon Nova Micro is usually picked for cheapest llm and fastest llm workloads, while Sonar Pro sees more deployments in research agent and rag.
