Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek V4 Pro (Reasoning, Max Effort) | Trinity Large Thinking |
|---|---|---|
| Input ($/M tokens) | $0.43 | $0.23 |
| Output ($/M tokens) | $0.87 | $0.88 |
Verdict. DeepSeek V4 Pro (Reasoning, Max Effort) wins the overall benchmark matchup 2–0 across 2 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, DeepSeek V4 Pro (Reasoning, Max Effort) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). DeepSeek V4 Pro (Reasoning, Max Effort) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek V4 Pro (Reasoning, Max Effort) is strongest on Coding Index (59.4), Intelligence Index (45.3). Trinity Large Thinking leads on Coding Index (25.8), Intelligence Index (18.7).
Speed. On throughput, Trinity Large Thinking generates tokens at 203 tok/s versus 78 tok/s — about 62% faster. On time-to-first-token, Trinity Large Thinking responds in 1230ms vs 1780ms, which matters most for chat-style UIs.
Provider. DeepSeek and Arcee AI sell to overlapping but distinct developer audiences: DeepSeek tends to ship frontier reasoning models with premium positioning, while Arcee AI 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): DeepSeek V4 Pro (Reasoning, Max Effort) costs $25.95 ($311/year); Trinity Large Thinking costs $20.10 ($241/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek V4 Pro (Reasoning, Max Effort) ≈ $3.89/run, Trinity Large Thinking ≈ $2.91/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek V4 Pro (Reasoning, Max Effort) ≈ $173/run, Trinity Large Thinking ≈ $134/run. Trinity Large Thinking 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.
