Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Command A | Claude Sonnet 5 (Adaptive Reasoning, Max Effort) |
|---|---|---|
| Input ($/M tokens) | $2.5 | $2 |
| Output ($/M tokens) | $10 | $10 |
Verdict. Claude Sonnet 5 (Adaptive Reasoning, Max Effort) takes the aggregate benchmark matchup 2–0 across 2 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the mid-tier bracket for output-token pricing. At 1.0× the per-million-token cost, Claude Sonnet 5 (Adaptive Reasoning, Max Effort) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Claude Sonnet 5 (Adaptive Reasoning, Max Effort) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Command A is strongest on Intelligence Index (7.5). Claude Sonnet 5 (Adaptive Reasoning, Max Effort) leads on Coding Index (71.5), Intelligence Index (55.3).
Speed. On throughput, Claude Sonnet 5 (Adaptive Reasoning, Max Effort) generates tokens at 76 tok/s versus 60 tok/s — about 20% faster. On time-to-first-token, Command A responds in 1860ms vs 184480ms, which matters most for chat-style UIs.
Provider. Cohere and Anthropic sell to overlapping but distinct developer audiences: Cohere tends to ship frontier reasoning models with premium positioning, while Anthropic often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
Workload cost. Workload scenarios (per million requests at 30M input + 15M output tokens): Command A costs $225.00 ($2700/year); Claude Sonnet 5 (Adaptive Reasoning, Max Effort) costs $210.00 ($2520/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Command A ≈ $32.50/run, Claude Sonnet 5 (Adaptive Reasoning, Max Effort) ≈ $30.00/run. At agent/realtime scale (200M input / 100M output per million requests): Command A ≈ $1500/run, Claude Sonnet 5 (Adaptive Reasoning, Max Effort) ≈ $1400/run. Claude Sonnet 5 (Adaptive Reasoning, Max Effort) becomes more attractive at higher volume — the absolute per-token pricing difference compounds when you ship at scale.
Recommendation. Both models have legitimate use cases — the right answer depends on whether you are optimizing for benchmark ceiling, latency, or unit cost. Start with the cheaper / faster model, evaluate against your specific task, and only switch if the upgrade shows a meaningful lift.
