Amazon Nova 2 Pro

Nova 2 Pro is Amazon's closed Bedrock flagship with a 1M-token context and multimodal input.

Best for

AWS-native workloads
Multimodal
Long-context

Watch out

Bedrock-only (closed) and still preview — pricing may change at GA. Older Nova siblings are sunsetting (Premier and original Sonic EOL 2026-09-14, Canvas/Reel 2026-09-30).

GPT-5.4 Mini

GPT-5.4 Mini is OpenAI's efficient mid-tier for high-volume, well-scoped tasks at $0.75/$4.50.

Best for

High-volume calls
Mixed workloads
Cost-sensitive production

Watch out

400K context (vs 1.05M on GPT-5.4/5.5/5.6); verify long-context needs.

When the cheaper one wins

GPT-5.4 Mini is cheaper on output at $4.50 per million tokens against $10 for Amazon Nova 2 Pro — about 2.2×. Use the cheaper tier for classification, extraction, summarisation, and any task where the expensive model’s extra score does not change the accepted output. The expensive one only pays if your hardest task actually fails on the cheap tier. These are standard-tier API rates, excluding batch and cache discounts.
