    Artificial Analysis

    Composite index blending reasoning, knowledge, and coding evals into one 0–100 score.

    Comparable with caveatOnly same-version scores are comparable. v4.3.2 was rebaselined (the top score fell from 66 on v4.1.1 to ~58), so v4.1.1 figures must not be compared with v4.3.2 figures — check measuredAt.

Pricing tiers

Amazon Nova 2 Pro: Standard tier $1.25/$10.00 per MTok on the cross-region global endpoint (Bedrock offer file published 2026-09-26); single-region +10% ($1.375/$11). Flex and batch $0.625/$5.00 global; Priority $2.19/$17.50. No cached-input price is published for Pro. Still preview (id amazon.nova-2-pro-preview-20251202-v1:0, secondary source).

Kimi K2.7 Code: $0.95/$4.00 per MTok — same rates as K2.6; cached input $0.19. Coding-focused build of the K2.6 recipe (1T total / 32B active).

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, and Amazon reportedly moved most Nova models to maintenance mode without naming 2 Pro among the survivors (secondary report), so do not assume GA. Nova Premier and the original Sonic reached end of life on 2026-09-14; Canvas and Reel follow on 2026-09-30.

Kimi K2.7 Code

Kimi K2.7 Code is Moonshot's coding-specialised build of K2.6 — same 1T MoE and 256K context, tuned for agentic coding workflows.

Best for

  • Agentic coding on open weights
  • Kimi ecosystem teams
  • Repo-scale refactors at K2.6 rates

Watch out

256K context matches K2.6, not K3's 1M; appears on the DeepSWE and CursorBench boards at mid-table scores.

When the cheaper one wins

Kimi K2.7 Code is cheaper on output at $4 per million tokens against $10 for Amazon Nova 2 Pro — about 2.5×. 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.

Evidence confidence: High

How strong and complete the evidence behind this comparison is — not a prediction of which model is better.

  • Pricing verified on both sides — Input and output rates are verified for both models.
  • 2/5 core specs verified on both sides — Not published for at least one side: max output, parameter count, reasoning levels.
  • 1 shared named benchmark with differing scores — Measured on: Artificial Analysis Intelligence Index.
  • Verified within the last 90 days — Newest catalog check was 2 days ago.
  • Both models carry source citations — Each side has at least two catalog sources on record.
