Kimi K2 Thinking vs Amazon Nova Pro
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Moonshot AI · Nov 2025
A trillion-parameter open reasoning agent that can chain 200–300 tool calls — the open-weights agentic standout of late 2025.
Amazon · Dec 2024
AWS's house multimodal model — chosen for Bedrock-native integration and AWS billing more than for benchmark wins.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Kimi K2 Thinking is about 1.3x cheaper per blended million tokens (3:1 input:output mix). Amazon Nova Pro also takes 300K of context versus 262K for Kimi K2 Thinking. And Kimi K2 Thinking is open-weights (Modified MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
