    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.

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.

DeepSeek V4.1 Flash

DeepSeek V4.1 Flash is DeepSeek's new default — an open-weight (MIT) multimodal MoE that DeepSeek says beats V4-Pro on performance, cost and speed.

Best for

  • Open-weight price-performance
  • High-volume hosted agents
  • Self-hosting with MIT weights

Watch out

Vendor benchmark claims are far ahead of its independent Artificial Analysis score (39.5 on v4.3.2); peak/off-peak billing means the hour you run matters.

When the cheaper one wins

DeepSeek V4.1 Flash is cheaper on output at $1.20 per million tokens against $10 for Amazon Nova 2 Pro — about 8.3×. 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.
