A complete head-to-head: pricing, context window, benchmarks, modality coverage, and openness, with a programmatic verdict synthesized from the underlying data.

Verdict by category
  • PriceAmazon Nova Lite

    Amazon Nova Lite is roughly 1.7× cheaper on output tokens ($0.24 vs $0.40 per 1M).

  • Context windowGPT-5 nano

    GPT-5 nano accepts 400K tokens vs 300K, 1.3× the room for long documents and codebases.

  • BenchmarksTie

    No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores.

  • ModalitiesTie

    Both handle text, vision.

  • OpennessTie

    Both are closed-weight, API-only.

It's a genuine coin-flip between GPT-5 nano and Amazon Nova Lite: 1 category wins each, with the rest tied. Amazon Nova Lite is roughly 1.7× cheaper on output tokens ($0.24 vs $0.40 per 1M). GPT-5 nano accepts 400K tokens vs 300K, 1.3× 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, vision), so the deciding factors are price, context, and raw quality. Both are closed-weight, API-only.

GPT-5 nano is the newer of the two, released 8 months after Amazon Nova Lite, which usually means a more recent knowledge cutoff and updated safety post-training. GPT-5 nano is usually picked for cheapest llm and fastest llm workloads, while Amazon Nova Lite sees more deployments in customer support and cheapest llm.
