Amazon Nova Premier
How TheRouter serves this differently from the vendor
AWS serves Nova Premier through Bedrock bedrock-runtime with Converse, InvokeModel, response streaming, guardrails, prompt caching (1K min / 4 checkpoints / 5-min TTL), and client-side tool calling. Structured Outputs are not supported. Global cross-region inference is not supported β only Geo inference (us.amazon.nova-premier-v1:0) and in-region (amazon.nova-premier-v1:0). Lifecycle is Legacy with EOL September 14, 2026.
TheRouter exposes Nova Premier as OpenAI-compatible /v1/chat/completions under amazon/nova-premier. Operational routing, pricing, context, modality, and supported-parameter fields are taken from the live TheRouter catalog. Snippets on this page are unverified until an operator-funded SNIPPET_VERIFY_APPROVED run completes; completeness is capped accordingly.
API guide
Chat completion
Call Nova Premier through TheRouter's OpenAI-compatible surface. TheRouter handles the Bedrock InvokeModel / Converse translation β your client stays OpenAI-shaped. Note the Legacy lifecycle: plan a migration to amazon/nova-2-lite before September 14, 2026.

}'Tool use (function calling)
Nova Premier supports client-side tool calling through Bedrock. Pass tools and tool_choice via the standard OpenAI-compatible fields.

"function": {
"name": "get_weather",
"parameters": {"type": "object", "properties": {"city": {"type": "string"}}}
}
}]
}'Vision input
Nova Premier is natively multimodal: pass images alongside text in the content array. Video and document inputs are also supported via Bedrock's native InvokeModel path.
