Nova 2 Sonic is a model record from **Amazon** in the Nova family. [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) The recorded model identifier or checkpoint is `v1:0`. Use that exact identifier when checking documentation or a provider listing. [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) ### How can you access Nova 2 Sonic? The catalog documents **API** access for Nova 2 Sonic. [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) As of the catalog check, this version was listed as available. [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription. ### What are Nova 2 Sonic's context and output limits? The documented **context window is 1,000,000 tokens**. [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) The documented **maximum output is 65,536 tokens**. [Source](https://docs.aws.amazon.com/nova/latest/nova2-userguide/what-is-nova-2.html) Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity. ### What dates are documented for Nova 2 Sonic? **Release date: December 2, 2025.** [Source](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-amazon-nova-2-sonic.html) This is a release milestone, not a knowledge or training cutoff. The source labels this “Model launch date.” Neither a knowledge cutoff nor a training-data cutoff is established here. A release date, repository upload or filename cannot supply those missing dates. ### What can Nova 2 Sonic receive and generate? Documented inputs: **text and audio**. [Source](https://docs.aws.amazon.com/nova/latest/nova2-userguide/what-is-nova-2.html) Documented outputs: **text and audio**. [Source](https://docs.aws.amazon.com/nova/latest/nova2-userguide/what-is-nova-2.html) Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation. **Catalog qualifications:** AWS Nova 2 model. Regional availability varies. Sonic is included because it supports conversational text and speech, rather than only transcription or speech synthesis. **Evidence still missing here:** complete input/output pricing and knowledge and training-data cutoffs. Missing documentation is not evidence that a feature is unavailable. Headless Thrones has not independently benchmarked this model for this reference. Evaluate it on representative work before choosing it; these facts do not rank its accuracy, reliability, speed or suitability against another model. Keep the exact version in view ## Other Nova models from Amazon. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [Nova 2 Lite](https://headlessthrones.com/models/amazon-nova-2-lite) API · 1,000,000 context tokens ### [Nova Lite](https://headlessthrones.com/models/amazon-nova-lite) API · 300,000 context tokens ### [Nova Micro](https://headlessthrones.com/models/amazon-nova-micro) API · 128,000 context tokens ### [Nova Premier](https://headlessthrones.com/models/amazon-nova-premier) API · 1,000,000 context tokens ### [Nova Pro](https://headlessthrones.com/models/amazon-nova-pro) API · 300,000 context tokens
