Amazon Nova Premier

amazonamazon/nova-premier

How TheRouter serves this differently from the vendor

As the vendor operates it

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.

On TheRouter

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.

Streaming

Stream tokens for long-running inference. Nova Premier supports response streaming through Bedrock bedrock-runtime.

  }'

Tool use (function calling)

Nova Premier supports client-side tool calling through Bedrock. Pass tools and tool_choice via the standard OpenAI-compatible fields.

curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-premier",
    "messages": [{"role": "user", "content": "What is the current weather in Tokyo?"}],
    "tools": [{
      "type": "function",
      "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.

        {"type": "image_url", "image_url": {"url": "https://therouter.ai/assets/vision-sample.png"}}
      ]
    }]
  }'
