Benchmark receipts

  • 2026-08-14: Artificial AnalysisComposite index blending reasoning, knowledge, and coding evals into one 0–100 score. Comparability: directly comparable — AA occasionally rebaselines the index scale between snapshots — a score captured on one date is only comparable to same-snapshot scores (check measuredAt).
  • 2026-04-24: DeepSeek family HF model card (vendor, Think Max, exact match)Real GitHub issue resolution: does the model's patch pass the hidden tests. Comparability: comparable with caveat — Post-audit vendor claims and pre-audit scores sit on different task trust levels; scaffolding (agent harness, compute budget) also dominates results. Never aggregate across scaffolds.

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).

DeepSeek V4 Flash

DeepSeek V4 Flash is the efficient open-weight (MIT) sibling of V4 Pro with a 1M-token context.

Best for

  • Open-weight deployments
  • Cost-sensitive inference
  • High-volume serving

Watch out

Peak/off-peak billing means the hour you run matters; off-peak is half price.

When the cheaper one wins

DeepSeek V4 Flash is cheaper on output at $1.32 per million tokens against $10 for Amazon Nova 2 Pro — about 7.6×. 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.
  • 3/5 core specs verified on both sides — Not published for at least one side: max output, parameter count.
  • 1 shared named benchmark with differing scores — Measured on: Artificial Analysis Intelligence Index.
  • Verified within the last 90 days — Newest catalog check was 7 days ago.
  • Both models carry source citations — Each side has at least two catalog sources on record.
