    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

Cohere Command A+: Azure-hosted Global rate $0.80/$3.20 per MTok (effective 2026-07-01; Data Zone $0.88/$3.52). Cohere-direct publishes no per-token price: open weights (Apache 2.0), a free rate-limited trial API, and Model Vault/enterprise licensing. Cohere calls it the last model in the Command A family. 218B/25B active sparse MoE.

DeepSeek V4.1 Flash: Official peak rates $0.30/$1.20 per MTok; off-peak $0.15/$0.60 (50% of peak). Cache hit $0.006 peak / $0.003 off-peak. Peak hours are weekdays 01:00–04:00 and 06:00–10:00 UTC. Open weights (MIT). The legacy deepseek-v4-flash and deepseek-v4-flash-vision-exp ids temporarily route here.

Cohere Command A+

Command A+ is Cohere's open-weight (Apache 2.0) 218B/25B sparse MoE for enterprise use.

Best for

  • Open-weight deployments
  • Enterprise RAG
  • Tool use

Watch out

The $0.80/$3.20 figure is the Azure-hosted rate, not a Cohere-direct price — Cohere itself sells licenses and a free rate-limited trial, so budget by deployment path.

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 $3.20 for Cohere Command A+ — about 2.7×. 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.
